The APR Short Shifter

Posted on November 24, 2015 – 9:44 am

APR is pleased to present the ultimate fully adjustable Short Shifter System for the 6 speed manual transmission!

The APR Short Shifter System is a comprehensive upgrade to the factory gear shifter assembly and is designed to reduces shifter movement, in all directions, while simultaneously improving shift quality. The system provides fine tuning of front-to-back and side-to-side movements to shorten shifts, counterweight adjustments for enhanced shift quality, and upgrades the weak points of the factory setup to provide years of worry free use. The upgrade is simple, easy to install, easy to adjust, and leaves the driver spending less time shifting and more time accelerating to victory.  To APR’s engineers, it’s the ultimate solution, but to the driver, it just works!

Quick Facts
Fully adjustable front-to-back movement
A slotted adjustment track on the shifter lever allows for precise adjustment of the shifter’s forward and backwards travel distance.

Fully adjustable side-to-side movement
A slotted adjustment track on the relay lever allows for precise adjustment of the shifter’s side to side travel distance.

Adjustable counterweights
Three stackable counterweights allow the driver to change the overall feel of the system to his or her own preference liking.

Stainless steel spline insert
The unique interlocking stainless steel insert prevents the input spline from wearing out over time. On cast and billet aluminum systems, wear of this part is common, which leads to sloppy shifts, component failure and potentially damage to the transmission.

Billet relay lever
The CNC-machined, thick billet aluminum relay lever is responsible for side-to-side movement and adjustment. This piece replaces the thin, flexible, stamped metal or plastic factory pieces.

Billet shift lever
The CNC-machined, thick billet aluminum shifter lever is responsible for front-to-back movement and adjustment. This component houses the counterbalance weights and replaces the factory cast, spline-wear-prone, piece.

Easy to adjust
Adjustment is as simple as loosening and tightening the pegs or adding more weights. No disassembly required!

Easy to install
The system mimics the factory shape making install simple and relatively easy.

All necessary hardware
The system includes new friction material, clips, locking nuts and stainless steel bolts and pegs. It’s a complete upgrade and complements the APR Shifter Cable Bracket.

Application Guide
The APR Adjustable Short Shifter system is sold as a complete system, or both pieces can be purchased separately. The system is designed to work with transverse 6 speed manual transmissions, commonly designated as the MQ350, O2M or O2Q. These transmission are found on nearly all MK5, MK6 and MK7 platform Golf/GTI/R/Jetta/GLI, MK2/MK3 A3/S3/TT, Octavia, Leon, Cupra, Scirocco and similar vehicles equipped with the the 1.8T, 2.0T, 2.0 TDI and 3.2L VR6 engines.

WaveTrac Differentials In Stock at Achtuning!

Posted on November 17, 2015 – 11:36 am

Enhanced No-Load Bias Ratio via its Wave Design Center Pack

One of the known shortcomings of a typical torque biasing differential is its loss of drive (behaving much like an open diff) under zero or near-zero torque conditions (for example, when there is ‘no-load’ applied through the drive-train, either at vehicle stationary and/or transition from engine driving vehicle to engine braking and back).

The Wavetrac® differential uses a patent pending design to improve grip in low traction conditions. Precisely engineered, converging / diverging wave profiles are placed on one side gear and its mating preload hub. As the two side gears rotate relative to each other, each wave surface climbs the other, causing them to move apart. This imparts an increased normal force through the side gears, increasing the bias ratio as a function of load. This increase occurs automatically only when conditions find it necessary, and it ‘reverts’ back to its nominal bias ratio quickly and seamlessly, maintaining optimal drive-ability and performance at all times. It’s like having two differentials in one: you get the benefit of a higher bias ratio when needed without detriment to the car’s handling.

Interchangeable Friction Plates Provide Controlled Bias

Here’s something else you won’t find in any other design:

The Wavetrac® diff’s behavior can be altered in the field to suit your needs. It comes standard with carbon-fiber bias plates for the best all around performance. Interchangeable plates using materials with different friction coefficients to fine-tune the bias ratio are sold separately.

These friction plates provide a mechanism to tune the response of the differential as a function of applied torque load. The applied torque load manifests itself as an axial load from the differential pinions into the housing. This axial force is then considered a normal force into the friction plate, and as a function of the effective coefficient of friction, will provide a resistive torque to the rotational motion of the differential pinions. The resistive torque will add to the resistance of relative rotation of all components within the differential. The resistive force, however, is non-uniform since it is a function of the axial load from the differential pinions. The unbalance of the resistive torque will manifest as non-uniform energy absorption within the differential causing a bias ratio.

Superior Design, Materials, and Construction

Designed from a clean sheet, the new Wavetrac® Differential brings current gear technology to the market. Internally, its gear tooth forms are optimized for strength and improved oil film retention over competitive designs. Our gear package is smaller, reducing overall mass, yet is more durable. Attention was also paid to the side gear/axle interface, putting as much material thickness as possible in this critical area – most important when power levels get high.

Each Wavetrac® Differential is crafted from the highest quality materials available. The internal gears are made from high strength 9310 alloy steel. The diff bodies are machined from case hardened steel billet. To complete the package, every Wavetrac® differential is built exclusively using high quality, high strength fasteners from ARP®, the world leader in fastener technology.

APR Presents: IS38 Turbocharger ECU upgrade for VW GTI & Audi A3

Posted on November 2, 2015 – 11:37 am

APR is pleased to present the OEM Golf R/S3 IS38 Turbocharger ECU upgrade for VW GTI and Audi A3 (MQB) platform vehicles!

APR’s IS38 Turbocharger ECU Upgrade is designed for use with the factory Golf R / S3 turbo on VW GTI & Audi A3 (MQB) platform vehicles and produces an asphalt shedding 386 HP on 93 octane fuel, and over 400 HP using APR’s upcoming Ethanol Flex Fueling upgrades! It’s even compatible with the factory downpipe exhaust system at lower output levels. Expect lightning fast response coupled with smooth daily driving and a much broader power band that pulls all the way to redline!

Using multiple vehicles across the world and in house, APR’s team of Calibration and Electrical Engineers spent the better part of a year mastering the factory Simos 18 engine management system to work seamlessly with the upgraded IS38 turbocharger unit. All critical aspects of the vehicle’s platform were taken into consideration and monitored through APR’s proprietary engine management logging tools to levels often not seen elsewhere in this industry. Through proper mapping, the ECU fully understands the hardware changes and operates correctly. As such torque delivery is smooth and flat, avoiding compressor surge, limitations in the factory fueling system, and limiting stress on the factory transmission. Cam phasing and valve lift operations are optimized, aiding in turbocharger spool, while allowing the engine to breathe more efficiently at higher engine speeds. Under various operational modes, lambda, ignition advance, requested torque, boost pressure levels and more were painstakingly optimized to produce maximum power without resorting to risky calibration shortcuts.

To APR’s Engineers, this is the ultimate pursuit of performance without compromise. To the driver, it just works! IS38 turbochargers are in stock at Achtuning. The VW (Mk7) GTI and Audi (8V) A3 categories of our online store will be updated shortly to include this turbo upgrade.


With OEM Downpipe
Wheel | Crank | Gain over Stock – 91 AKI / 95 RON
Wheel | Crank | Gain over Stock – 93 AKI / 98 RON
Wheel | Crank | Gain over Stock – 100 AKI / 108 RON
Wheel | Crank | Gain over Stock – Ethanol

With APR Downpipe
Wheel | Crank | Gain over Stock – 91 AKI / 95 RON
Wheel | Crank | Gain over Stock – 93 AKI / 98 RON
Wheel | Crank | Gain over Stock – Ethanol

* APR recommends and tunes with Sunoco GT 260 for 100 AKI mode and Sunoco GT 260 Plus for 104 AKI mode. Never use lower octane than specified by the mode.

* Ethanol software REQUIRES APR’s upcoming Ethanol Flex Fueling upgrades.

* Max increases are based on APR’s actual measured stock values and not those reported by VAG. | RON = ROW Fuel Grades | AKI = NAR North American (RON+MON)/2 Fuel Grades.

* Reported wheel figures measured using APR’s in-house Dynapack Dynamometer with a US Spec MK7 GTI with factory IS38 turbocharger, APR Cast Downpipe, APR Intake System and APR Intercooler, using SAEJ1349 correction and an average of multiple runs. Crank figures are estimated based on the measured wheel figures. Results may vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, other variables and other modifications.

* Race Fuel Information: Higher octane fuel typically allows APR’s engineers to create more power and torque by achieving greater ignition advance. However, on this application, APR’s engineers were able to achieve MBT, or minimum spark timing for best torque, on 93 AKI fuel with the APR downpipe. MBT is essentially the point where greater ignition advance no longer results in more power and torque. By using APR’s upcoming Ethanol Flex Fueling upgrades and Ethanol fuel, greater peak power was achieved due to the fuel’s highly oxygenated nature.

Requirements and Recommendations

APR’s IS38 Turbocharger ECU Upgrade is sold as software only. The factory turbocharger necessary for this upgrade is in stock at Achtuning.

  • Turbocharger – An unmodified, OEM IHI IS38 Turbocharger is required. APR recommends using the latest factory revision (06K145722H as of Oct 20th, 2015) with APR’s Turbo Muffler Delete and recommends replacing factory one time use nuts, bolts, gaskets, and crush washers.
  • Intake – The APR Carbon Fiber Intake System is highly recommended. This setup is necessary to achieve the advertised power figures.
  • Exhaust – Upgrading the factory downpipe is required for the higher output downpipe software. APR highly recommends using the APR Cast Downpipe System as this system is necessary to achieve the advertised power figures. The factory catback exhaust does not need to be modified.
  • Intercooler – Upgrading the factory intercooler is highly recommended. APR recommends using the upcoming APR Intercooler system. This setup is necessary to achieve the advertised power figures consistently.
  • Ethanol Support: – APR’s upcoming Ethanol Flex Fueling upgrades are required to run Ethanol calibrations. No fueling upgrades are required for conventional gasoline.
  • Spark Plugs – Upgrading the spark plugs with Denso Iridium IKH24, gapped to 0.024″ ±0.002″ or 0.6mm ±0.05mm with a change interval of 10-15,000 mi or 16-24,000 km is required for engine longevity and safety.
  • Transmission – APR recommends the APR IS38 TCU Upgrade for maximum performance on DSG / S Tronic models. A clutch upgrade may be necessary on manual transmission vehicles.
  • Oil, Coolant and Lubrication – APR recommends using Motul oils, coolants and lubricants with APR’s Oil Catch Can System.
