Audi SQ5 Owners! It’s your turn!!

Posted on July 10, 2014 – 9:00 am

Achtuning is pleased to present the ultimate engine control unit (ECU) upgrade for the Audi SQ5 3.0 TFSI V6.  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.

The Continental SIMOS 8.5 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 in-house 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 red-line.  APR’s ECU Upgrade increases supercharger boost pressure and optimizes cam timing, ignition timing, lambda and more to produce higher output. 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 Stage I 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 403 horsepower and 371 ft-lbs of torque with 93 AKI octane fuel. Large gains were seen throughout the power band, including an additional 50 horsepower and 43 ft-lbs of torque.  Even higher figures were achieved using 100 AKI octane race fuel.  The increase in power directly translates to an exceptionally quicker vehicle.

For those demanding more torque and power, the APR Supercharger Pulley Upgrade is the answer.  Spinning the supercharger faster increases air flow allowing for higher boost levels and more power.  The gain in torque is felt immediately, but the results are present across the entire power-band. Expect 419 horsepower 93 AKI octane fuel and 445 horsepower on 100 AKI octane race fuel!  Software is included as a free upgrade for APR Stage I customers with the purchase of an APR Supercharger Pulley Upgrade.

APR’s ECU upgrade is the best power per dollar modification for the new 3.0 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 Development Difference

APR DirectPort Programming:

APR’s patented DirectPort Programming is now available for the Simos 8.5 ECU!  With a simple connection to the Internet we have direct access to APR’s latest ECU upgrades for loading directly over the vehicle’s OBD-II port.  This completely eliminates the need to remove and open the ECU for currently available files and can be uninstalled at any time!

APR ECU Explorer:

APR’s proprietary ECU Explorer gives APR’s Calibration Engineers unparalleled access to the vehicle’s entire engine management system.  Typical commercially available data logging tools, used by most tuners, only allow logging up to 12 engine-operating variables at extremely low data rates.  These tools are also limited to a small, specific list of variables.  APR’s ECU Explorer is capable of logging every variable found within the ECU.  It’s capable of logging well over 100 variables at once with data rates as high as 100 samples per second.  Synchronous data logging is available for fine-tuning.

APR ECU Composer:

APR’s proprietary ECU Composer is used for altering the engine management system.  With full access to every table, map and variable within the ECU, APR’s Calibration Engineers are not limited to a handful of maps as is common for most tuning companies.  ECU Composer takes calibration to a new level with APR’s Quick Flashing.  APR’s Calibration Engineers can reflash the ECU in seconds rather than waiting lengthy periods of time between each flash.

APR ECU Assembly:

APR’s Electrical Engineers have the ability to alter the code structure of the ECU.  Through code levels changes, APR’s Engineers are able to add features to the ECU.  Other changes allow higher torque limits than those achievable through only modifying calibration data or using piggyback devices as is the case for many tuners.  This allows APR’s engineers to often not require transmission software to meet or exceed advertised gains.  On the highly modified end, this allows APR to make turbo upgrades operate as if intended by the OEM.

APR ECU Upgrades and TDI Info

Posted on August 9, 2012 – 1:01 pm

So far we’ve had several successful APR ECU upgrades on 2.0 TDI (140hp) Audis and VWs and we want to give everyone some detailed information with regard to availability of an ECU upgrade for your TDI. When you come to see us, we will plug into your OBD-II port and load APR’s Direct Port Programming online flashing suite. The computer will scan your car to see if software is available. If it is, you can flash and go on your way. If it isn’t, we’ll do what’s called a “Code Extract” to send your ECU information to APR for software creation.

Currently we are extracting and flashing ECU’s with the 1796 processor. However, vehicles with the 1797 ECU found in select new vehicles are still in development. We can take a good guess which processor revision is which based on your ECU Box code, however, the only way to be sure is to open the ECU and check.

Audi/VW/Seat/Skoda have MANY ECU part numbers and revisions for each vehicle in their fleet, so typically during the launch of a new software code, there’s some lag time before all of the codes are available. Codes will not become available unless APR actually sees them, which means taking a trip to come see us to do that scan/code extraction will speed up the process.

If you have a Ross Tech VCDS cable, you can do some homework to find what you have. Just follow this guide:

At this point, the following ECU box codes & revisions are available to flash right now:

2.0TDI CJAA 03L906019CL S7966
2.0TDI CJAA 03L906019CM S7967
2.0TDI CJAA 03L906019DA S9144
2.0TDI CJAA 03L906019DA S8217
2.0TDI CJAA 03L906019DB S9047
2.0TDI CJAA 03L906019DB S7970
2.0TDI CJAA 03L906022PB S8216
2.0TDI CBEA 03L906022SQ S7968

If you’re not on that list, you may need to be code extracted. However, we will not need to extract your ECU if you’re on the lists below.

Here are the other ECU codes we currently have and are waiting for APR Engineering to release:

2.0TDI CBEA 03L906022SQ S7276
2.0TDI CBEA 03L997016N S8680
2.0TDI CBEA 03L997016P S8681

Lastly, here are other codes we are waiting for APR’s Engineering team to test before they can be bumped up to the next level for a release:

2.0TDI CJAA 03L906019EE S1181
2.0TDI CJAA 03L906019EE S3521
2.0TDI CJAA 03L906019EF S1182
2.0TDI CJAA 03L906019EH S3523
2.0TDI CBEA 03L906019EJ S1466
2.0TDI CJAA 03L906019HG S2261
2.0TDI CJAA 03L906019HH S2260
2.0TDI CJAA 03L906019HH S3524

Hope this clears up any questions or confusion out there with regard to “select” TDI software availability from APR. If you have additional questions or concerns, please do not hesitate to contact us!
