APR 3.6L FSI VR6 ECU Upgrade

Automobile Magazine Review of APR Software

APR is pleased to present the ultimate ECU Upgrade for the 3.6L FSI VR6 with Bosch MED9 Engine Management.

After long nights and many hours of testing, developing and more testing, we’re pleased to offer you an ECU recalibration that is second to none. APR’s extensive research and development provides you with a powerful ECU upgrade with no loss of drivability or reliability. Expect faster acceleration, improved throttle response and more power across the entire power band.

APR’s 3.6L FSI VR6 ECU Upgrade is an expertly recalibrated engine control strategy that primarily remaps the engine’s air fuel ratio and ignition timing, within the factory Bosch MED9 ECU, to provide smooth and reliable power as if intended by the OEM.  APR’s ECU Upgrade is developed to work within the OEM and Tier 1 Supplier specifications for engine component stress tolerances and performance specifications. Available in octane-specific variations, APR’s calibrations allow you to take advantage of fuel quality available in your area.

APR Stage I ECU Upgrade

The APR Stage I ECU Upgrade gives you higher peak numbers of 301 HP/283 FT-LBS on 93 (R+M)/2 octane. As much as 12 HP and 23 FT-LBS of torque are available through the power band. APR’s ECU Upgrade is the best power per dollar modification for the new 3.6L FSI VR6 and gives it just the extra edge these cars lack from the factory without pushing the limits. With factory-like smoothness and drivability, APR’s ECU upgrade will fill the void in an otherwise excellent car.

rabbitAcceleration Enhancements:
Beyond power and torque enhancements, APR’s Calibration Engineers were able to increase the acceleration rate of the 3.6L FSI VR6 through other calibrations changes. Throttle and ignition delays are removed resulting in a more responsive pedal without altering overall throttle sensitivity.

ecoIncreased 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 your driving style and fuel quality, you may see better miles per gallon!

vmaxSpeed Limiter Removed:
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 your fun!

Left Foot BrakingLeft Foot Braking:
APR's Left Foot Braking feature allows more control over the vehicle’s throttle. The factory equipped 3.6L FSI VR6’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 3.6L FSI VR6 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 ECU ExplorerAPR 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 many variables at once with data rates as high as 100 samples per second. Synchronous data logging is available for fine-tuning.

APR ECU ComposerAPR 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 on the this engien with APR's Quick Flashing. APR’s Calibration Engineers can reflash the ECU only a minute later rather than waiting 10 to 20 minutes between each flash.

APR ECU AssemblyAPR ECU Assembly:
APR’s Electrical Engineers have the ability to alter the code structure of the ECU to add features not available from the factory.
