Audi (B8) A4 APR Software Update!

Posted on February 27, 2015 – 9:00 am

With over half a decade of development poured into this platform, APR’s Engineers are pleased to deliver several free upgrades to our existing customers. APR Stage I, Stage II and their K04 Turbocharger ECU upgrades are now revised with APR’s new calibration strategies designed to produce a fantastic driving experience with more power and torque on tap!

APR’s calibration experts spent months working with the various ECU, hardware and octane configurations to deliver a driving experience second to none. Major improvements were made to the way the throttle behaves, leaving the driver to feel more connected to the vehicle than ever before. With control and response maximized, APR’s engineers set out to increase power while keeping factory comforts in mind during part throttle driving. Engine load, valve lift, cam phasing and boost levels were all optimized to ensure the engine was breathing as freely as possible for maximum output. Ignition, lambda and other aspects of the direct injection fueling system were tweaked to raise and refine power further. The end result is a fantastic leap in performance and response that wakes up the engine sooner in the RPM band and carries horsepower and torque further towards redline.

APR Rolling Out New Products!

Posted on February 25, 2015 – 10:00 am

APR is changing up their game in a big way and we are starting to see the fruits of their labor as  fresh new product is coming down the pipeline.  As always, our commitment to offering and STOCKING your APR performance upgrades means we will be one of the first distributors to receive them so you can walk out the door with parts in hand or simply arrange a time for install.  “Go APR” at Achtuning!

APR Presents the 1.8T/2.0T EA888 Gen 3 Boost Tap – v2!

The APR Boost Tap for the 1.8T and 2.0T EA888 Gen 3 engines is a simple, yet elegant solution for referencing boost pressure and vacuum as is commonly necessary for boost gauges. The boost tap plugs into an unused port on the factory intake manifold and doesn’t interfere with the factory T-MAP sensor.

 

 

Traditionally boost is tapped by spacing out the factory T-MAP sensor on top of the intake manifold. However, APR’s engineers discovered using this location lead to inconsistencies in intake air temperature readings and potentially a loss of power. Upon this discovery, APR’s engineering team went back to the drawing board and came up with a new and unique solution.

 

Kit Includes:

  • 1 Billet boost tap
  • 2 Viton o-ring seals
  • 1 Stainless steel barbed connection point
  • 1 Brass “No-buzz” mechanical boost gauge restrictor pill
  • 1 Tap cap
  • 5 Stepless OEM style ear clamps
  • 96 Inches of 200 PSI hose
  • 1 T-fitting
  • 5 Black cable ties
  • 1 Bag of anti-sieze
  • 1 Tapping tool

 

Utilizing the included punch tool on a warm engine, a boost and vacuum reference port is easily spread opened on the factory intake manifold. The billet aluminum boost tap then connects to the port and uses dual Viton o-ring seals for leak free operation. The reference hoses connect to the rear of the tap via a barbed stainless steel connection point and conveniently routes through the engine bay.

In addition to the boost tap, APR provides several extra components to help suit each individual’s needs. For those requiring more than one reference source, a T-fitting allows for more tapping points. In the case where a mechanical boost gauge is used, the brass restrictor pill limits flow and cures gauge buzz. Just less than 100 inches of 200 PSI hose is included with OEM style ear clamps and black cable ties to allow for neatly routing hose through the engine bay.

APR Presents the 1.8/2.0T EA888 Gen 3 Cast Downpipe Exhaust System!

 

Upgrading the restrictive factory downpipe with the APR Cast Downpipe Exhaust System is a great way to increase performance and add a sophisticated growl to the exhaust note. Ideal performance is achieved through expelling exhaust gasses at maximum velocity through APR’s proprietary, low-turbulence, investment cast downpipe. Designed and assembled in-house, the system utilizes only premium materials and world-class manufacturing techniques to deliver unmatched quality and reliability.


 

Quick facts:

  • Designed and assembled in-house.
  • T304L stainless steel construction.
  • Argon back-purged TIG welding.
  • Investment cast downpipe.
  • 77mm inlet with integrated flange.
  • Low profile, sealed/corrugated flex section.
  • 76mm outlet with integrated bracket.
  • 8mm billet bracket.
  • 76mm brushed and de-burred piping.
  • Non-swedged/slip-fit/flanged piping.
  • Investment cast o2 bung.
  • 300 cell, 100mm x 100mm GESI catalyst.
  • OEM-style slip-on clamps.
  • Reducer for OEM catback compatibility.
  • APR Stage II ECU Upgrade price waived.
  • Limited lifetime warranty.

The factory downpipe system consists of smaller, 63mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions all in a unique package only APR can deliver.

Detailed component photos and information

The APR Cast Downpipe Exhaust System is a complex system designed to deliver maximum performance. Each component was designed and developed with the absolute best in performance, strength, reliability and quality in mind.

Cast Downpipe Inlet and Outlet

The exhaust system features a strong, investment cast, T304L inlet and outlet designed to maximize flow and minimize turbulence. By casting the inlet, APR’s engineers were able to create a smooth and high-flow exhaust path that maximized flow through swept blends and shapes that are otherwise not possible through conventional fabrication techniques. The inlet perfectly matches the factory turbocharger’s 77mm outlet and gradually necks down over a long distance to further enhance performance. The mounting flange and bracket are integrated into the casting, and TIG welding at the flex section ensures a clean inner surface eliminating turbulence, vortices and eddies to the highest degree.

With a nominal wall thickness of 2.55mm the downpipe is strong and produces a refined exhaust note compared to thin wall tubing systems. The cast sections undergo a tumbling process to smooth and de-burr any imperfections inside the pipe, while simultaneously enhancing the exterior finish. Lastly, all necessary surfaces are CNC machined for an accurate fit.

Flex Section

APR’s engineers specified a T304L stainless steel, OEM-style flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The low profile design and minimal use of bradding material eliminates clearance issues common with other designs that can billow, rub, rattle and fray over time.

Bracket

Designed to stand the test of time, the bracket is CNC machined from 8mm-thick billet T304L stainless steel and the hanger feet are threaded into place, eliminating the need for welds. Weight is removed from the bracket, wherever possible, while not hindering its structural integrity. The bracket attaches to the cast downpipe’s integrated mounting bracket, and CNC machined spacers enable compatibility across multiple vehicles.

Piping

The APR Downpipe Exhaust System features premium grade T304L stainless steel for its excellent appearance, strength and corrosion resistance properties. The pipe is rolled to the 76mm European standard diameter with a 1.5mm wall thickness and a seemingly non-existent weld seam.

Pipe is cut to length in-house via APR’s CNC-controlled bandsaw to an accuracy of .25mm, ensuring a precise fit. Each pipe is de-burred, and the exterior finish is brushed to give the exhaust piping a clean and attractive appearance worthy of the APR name. APR’s fabrication team uses argon back-purging during the welding process, leaving a clean and smooth interior surface, and TIG welding for strength and appearance. Lastly, no swedging or slip-fitting is necessary due to APR’s OEM-style clamp design, leaving smooth and less turbulent connection points.

Clamps

APR’s engineers specified a T304L stainless steel, OEM-style exhaust clamp designed to eliminate the need for flanges, swedging, or slip fittings. By using this low profile design, the exhaust system can be positioned higher in the exhaust tunnel and away from the ground with better clearances compared to flanged setups. Each clamp allows for less turbulence and greater accuracy at the connection points as the pipes simply butt up to one another rather than the ambiguity and voids associated with swedged slip fittings. Furthermore, the clamp doesn’t rely on deforming the pipe to provide a tight seal, making install and removal more convenient.

O2 Sensor Bung

APR’s Engineers paid special attention to the details when designing the APR Cast Downpipe Exhaust System all the way down to the oxygen sensor bung. APR’s O2 bungs are investment cast from T304L stainless steel and are curved to perfectly fit on 76mm piping, without protruding into the pipe, as this would further impede airflow beyond the sensor itself. The bungs are TIG welded to the piping and back-purging is used to ensure the interior surface is smooth and clean.

Catalyst

APR’s engineers specified a high-quality and high-flow GESI metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalyst’s specifications.

Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.

Reducer

A simple and removable, T304L stainless steel reducer, featuring a smooth transition, is included, making the APR Cast Downpipe Exhaust System directly compatible with the OEM catback exhaust system.

Oxygen Sensor Harness

A high quality oxygen sensor extension harness is included as the catalyst and sensor bung is relocated further away from the turbocharger.

The factory downpipe system consists of smaller, 63mm piping with varying bends and multiple restrictive high-cell-count catalysts, all of which contribute to a less than ideal flow path and hindered performance. APR’s engineers took a multi-step approach to maximizing flow, reducing under hood temperature, and eliminating unnecessary restrictions all in a unique package only APR can deliver.

Detailed component photos and information

The APR Cast Downpipe Exhaust System is a complex system designed to deliver maximum performance. Each component was designed and developed with the absolute best in performance, strength, reliability and quality in mind.

Cast Downpipe Inlet and Outlet

The exhaust system features a strong, investment cast, T304L inlet and outlet designed to maximized flow and minimize turbulence. By casting the inlet, APR’s engineers were able to create a smooth and high-flow exhaust path that maximizes flow through swept blends and shapes that are otherwise not possible through conventional fabrication techniques. The inlet perfectly matches the factory turbocharger’s 77mm outlet and gradually necks down over a long distance to further enhance performance. The mounting flange and bracket are integrated into the casting, and TIG welding at the flex section ensures a clean inner surface eliminating turbulence, vortices and eddies to the highest degree.

With a nominal wall thickness of 2.55mm the downpipe is strong and produces a refined exhaust note compared to thin wall tubing systems. The cast sections undergo a tumbling process to smooth and de-burr any imperfections inside the pipe, while simultaneously enhancing the exterior finish. Lastly, all necessary surfaces are CNC machined for an accurate fit.

Flex Section

APR’s engineers specified a T304L stainless steel, OEM-style flex section that is fully sealed with a corrugated inner lining to improve flow and reliability. The low profile design and minimal use of bradding material eliminates clearance issues common with other designs that can billow, rub, rattle and fray over time.

Bracket

Designed to stand the test of time, the bracket is CNC machined from 8mm-thick billet T304L stainless steel and the hanger feet are threaded into place, eliminating the need for welds. Weight is removed from the bracket, wherever possible, while not hindering its structural integrity. The bracket attaches to the cast downpipe’s integrated mounting bracket, and CNC machined spacers enable compatibility across multiple vehicles.

Piping

The APR Downpipe Exhaust System features premium grade T304L stainless steel for its excellent appearance, strength and corrosion resistance properties. The pipe is rolled to the 76mm European standard diameter with a 1.5mm wall thickness and a seemingly non-existent weld seam.

Pipe is cut to length in-house via APR’s CNC-controlled bandsaw to an accuracy of .25mm, ensuring a precise fit. Each pipe is de-burred, and the exterior finish is brushed to give the exhaust piping a clean and attractive appearance worthy of the APR name. APR’s fabrication team uses argon back-purging during the welding process, leaving a clean and smooth interior surface, and TIG welding for strength and appearance. Lastly, no swedging or slip-fitting is necessary due to APR’s OEM-style clamp design, leaving smooth and less turbulent connection points.

Clamps

APR’s engineers specified a T304L stainless steel, OEM-style exhaust clamp designed to eliminate the need for flanges, swedging, or slip fittings. By using this low profile design, the exhaust system can be positioned higher in the exhaust tunnel and away from the ground with better clearances compared to flanged setups. Each clamp allows for less turbulence and greater accuracy at the connection points as the pipes simply butt up to one another rather than the ambiguity and voids associated with swedged slip fittings. Furthermore, the clamp doesn’t rely on deforming the pipe to provide a tight seal, making install and removal more convenient.

O2 Sensor Bungs

APR’s Engineers paid special attention to the details when designing the APR Cast Downpipe Exhaust System all the way down to the oxygen sensor bungs. APR’s O2 bungs are investment cast from T304L stainless steel and are curved to perfectly fit on 76mm piping, without protruding into the pipe, as this would further impede airflow beyond the sensor itself. The bungs are TIG welded to the piping and back-purging is used to ensure the interior surface is smooth and clean. Lastly, a billet T304L stainless steel bung plug is included to cap off extra ports not needed on some models.

Catalyst

APR’s engineers specified a high-quality and high-flow GESI metal 300-cell catalyst ideal for forced induction application. During dyno testing, the 100mm x 100mm design showed no measurable loss in power, thanks to the catalyst’s specifications.

Internally the catalytic converter features a proprietary blend of precious metals and loading technology that helps to reduce emissions and smell common on cat-less setups. With performance in mind, the catalyst is placed far away from the turbo outlet to reduce turbulence in the downpipe and to help reduce under-hood temperature. The low-profile catalyst features a fully captured substrate brick, which is furnace braised to the outer mantle and physically captured by the diffuser cones preventing rattling, rotation, and damage to the substrate. Subsequently, a byproduct of running the catalyst is a reduction in noise, making the system as a whole more pleasing to the ear.

Reducer

A simple and removable, T304L stainless steel reducer, featuring a smooth transition, is included, making the APR Cast Downpipe Exhaust System directly compatible with the OEM catback exhaust system.

The APR Difference:

The Engineering and Designing Phase

In the past APR worked with other manufacturers to develop a limited range of private-label exhaust systems outside the scope of APR’s internal development and manufacturing capabilities. Understanding the limits of such a program, combined with APR’s desire to deliver higher-quality products in a timely manner with better customer support, APR invested in internalizing the program. With the release of this exhaust system and the others like it, APR is pleased to present our first systems fully designed and engineered in-house from the ground up!

Design and development begins with the use of APR’s professional grade in-house coordinate measuring machines. APR’s engineers have full access to a Romer Absolute arm with integrated laser scanner, FaroArm and Creaform 3D laser scanner for collection of special constraints surrounding the factory exhaust system. The engineers scan the vehicles and create detailed 3D maps of their design environment while designing each system in PTC Creo 3.0 CAD software.

Using APR’s in-house stereolithography 3D printer, rapid prototypes are created for fitment on the vehicle. The design is easily and quickly verified, and if necessary, changes can be made. Once adequate clearances and fitment is confirmed, especially in areas that move under load, physical quick-cast prototypes are created and fitted for final verification through real-world use.

APR’s world-class manufacturing partners from around the globe are responsible for manufacturing each component that falls outside of APR’s internal capabilities. Working closely with each manufacturer, APR’s engineers supply CAD models, materials specs, and other design specifications and work hand-in-hand with the manufacturer to develop the components. The end result is a collection of components, wholly unique to the APR name, awaiting final finishing, assembly and quality control at APR’s 78,000 square foot facility in Opelika, Alabama in the USA.

The Fabrication, Finishing and Assembly Phase

Manufacturing takes place both internally and externally to APR while finishing and assembly is completed in-house. APR’s fabrication team cuts, brushes and de-burrs premium grade T304L stainless steel piping for use in each midpipe. Then each cast component is sent through the ceramic vibrating tumblers to smooth and de-burr surface imperfections. Each component is then cleaned by hand and prepared for assembly.

APR’s fabrication experts TIG weld each component, creating reliable, high quality and attractive welds. Each component is back-purged with argon during the process ensuring the weld is strong and consistent, as well as clean throughout. With this process complete, the APR Cast Downpipe Exhaust System is born!

Final Quality Control

APR has placed a large emphasis on improving quality control across various product lines, and the exhaust program is not excluded. To ensure the systems are delivered as advertised, APR’s engineers have taken a multi-step approach that encompasses many techniques that go beyond the industry standard.

Metallurgy Testing

APR’s engineers request full metallurgy reports with each batch of components to ensure the components are made with the T304L stainless steel grades specified on the original design prints. This information is then cross-referenced against randomly selected and independently tested samples before the components are released for assembly.

Dimensional Inspection

Great designs only matter if the manufacturer delivers the components as expected. To help ensure the designs are as specified, APR’s engineers randomly select components and conduct full dimensional inspections using in-house 3D laser scanning equipment. Tolerances are digitally checked against the original specifications and passed or failed based on the results.

Fixtures

Operating in an environment designed for accuracy and repeatability, APR’s fabrication experts leave little room for error during the final assembly phase. Jigs and fixtures, created in-house, live on custom-specified fabrication tables featuring repeatable indexing holes and extremely flat surfaces. This working environment ensures the highest level of quality control during the assembly process and safeguards against dimensional variations potentially created during the manufacturing process. The end result is a system that fits every time as it’s true to the original design specifications.
Visual Quality

When hand-building the products in-house, an extra level of control takes place. Components are visually checked for imperfections, and items that fall out of quality standards are rejected. The products are then packaged with care before being distributed across the world.

APR’s confidence in the system’s quality allows for a limited lifetime warranty.

APR Shifter Cable Bracket

Posted on October 29, 2014 – 9:00 am

 

Achtuning is pleased to present APR’s latest, the APR Shifter Cable Bracket!  Through countless years of processional racing, APR Motorsport identified the factory shifter cable bracket system as a source of sloppy shifts, missed gears, bracket and bushing failure and even transmission failure. The factory shifter cable bracket is made from plastic with rubber bushings. Over time the bushings wear out, and during long races, heat can cause the bracket to flex and break. To alleviate all issues related with the factory design and not just some, APR’s Mechanical Engineers created the ultimate and final upgrade:The APR Solid Shifter Cable Bracket.

Key Points:

  • Addresses both issues with the OEM design
  • Cast 304 stainless steel eliminates flexible plastic OEM design
  • CNC-machined solid mounts eliminate rubber OEM bushings
  • Removes play, slop and the rubbery feeling of the OEM part
  • Will not flex, wear out and / or break under prolonged use
  • Lifetime warranty

 

The APR Solid Shifter Cable Bracket is made from cast 304 stainless steel and eliminates the rubber bushings with solid, CNC-machined mounting points. The bracket and bushings will not wear out over time or fatigue under heat and prolonged use, minimizing the potential for transmission damage. With the play and rubbery slop of the OEM component removed, it’s easier to find gears. Expect the feedback from each shift to remain true and confident with a more direct and solid feeling.

Audi (B8.5) A4 / A5 / Q5 & (C7) A6 2.0 TFSI VL (Flex/Non Flex) ECU Upgrade!

Posted on October 3, 2014 – 11:34 am



APR has released their Audi (B8.5) A4 / A5 / Q5 & (C7) A6 2.0 TFSI VL (Flex/Non Flex) ECU upgrade!!  APR’s ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.  APR’s patented EMCS functionality puts the control of your engine’s operation at your fingertips and allows for additional features and options to be installed to your OEM ECU.





The Bosch MED17 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

APR’s Calibration Engineers spent months calibrating the engine management system, including many hours of chassis dyno development.  With a thorough understanding of the ECU’s torque structure, APR’s Calibration Engineers properly increased engine load to produce more power and torque from idle to redline. APR’s ECU Upgrade increases turbocharger boost pressure and optimizes cam timing, valve lift, ignition timing, lambda and more to produce higher output.  Ethanol ‘flex fuel’ compatible engine variants can take advantage of automatic E85 map blending to add power simply by filling the tank.  Using APR’s proprietary high-speed data logging suite, the calibration team closely monitored the effects of these changes to ensure a powerful ECU upgrade without derogating the engine’s drivability or reliability.

APR’s ECU Upgrade will provide an excellent leap in power and torque while retaining OEM knock control sensitivity and other built in safety features.  The result is safely achieved power, optimized for various fuel grades found around the world.  We call it Performance Without Compromise!

APR ECU Upgrade



The APR Stage I ECU Upgrade is designed to work without requiring other changes to the vehicle’s hardware.  With the ECU Upgrade alone, APR’s Calibration Experts measured higher peak figures of 284 horsepower and with 334 ft-lbs of torque 93 AKI octane fuel.  Large gains were seen throughout the power band, including an additional 57 horsepower and 85 ft-lbs of torque.  By adding E85 to the tank on the Ethanol compatible variants, automatic Ethanol map blending adds even more power, resulting in 85 horsepower and 135 ft-lbs of torque.  The increase in power directly translates to an exceptionally quicker and more enjoyable vehicle.

By simply adding an APR downpipe exhaust system, APR’s Stage II software, a free upgrade to existing APR Stage I customers, takes performance even further. on 93 AKI fuel peak figures of 302 horsepower and 334 ft-lbs of torque were achieved.  Again, by adding E85 on flex fuel compatible variant, 318 horsepower and 405 ft-lbs of torque was achieved!

APR’s ECU upgrade is the best power per dollar modification for the new 2.0 TFSI engine and takes the vehicle’s performance to similar levels typically reserved for higher output, sporty models without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent vehicle.

Acceleration Enhancements:


Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the vehicle through other calibrations changes. Ignition delay is reduced resulting in a more responsive pedal without altering overall throttle sensitivity. Furthermore, drivability was greatly improved by reducing the throttle lag commonly noticed at slow speeds and while reapplying throttle after decelerating.

Increased Fuel Economy:


APR’s Calibration Engineers paid close attention to several parameters directly related to fuel economy, especially while cruising at highway speeds. Depending on driving style and fuel quality, better miles per gallon may be achieved!

Speed Limiter:


APR’s ECU upgrade increases the vehicle’s top speed limiter for blistering sprints around the track or across the Autobahn without the speed limiter shutting down the fun!

Left Foot Braking / Brake Boosting:


APR’s Left Foot Braking feature allows more control over the vehicle’s throttle.  The factory equipped vehicle’s throttle input is disabled while pressing the accelerator and brake at the same time.  Left Foot Braking, a common motorsport driving technique, allows the driver complete control over the vehicle’s throttle and braking system, which may give the vehicle the edge it needs at the track.  As is with all features APR adds to the ECU, this feature may be removed upon request.

The APR downpipe exhaust system is a perfect upgrade for any RS4 owner looking to get the most out of their 4.2L FSI V8.  The system features a completely unrestrictive design capable of supporting power output far beyond that of a fully built APR Stage 3+ TVS1740 supercharged engine.



Built as a direct OEM replacement, the downpipes are simple to install and provide more than adequate clearance from surrounding hardware. By removing four large and restrictive OEM catalytic converters, the downpipes provide a clear path for exhaust gasses exiting the headers. Connection to the factory catback exhaust is made simple by utilization of the factory hardware.



Constructed from T304 stainless steel, and fully tig welded, the system is designed to last through the harshest of conditions and is backed by a full lifetime warranty. Expect high quality components that enhance the sound and performance of the 4.2L FSI V8 and will stand the test of time.
