APR Stage 1 ECU Tune
APR is pleased to present the ultimate engine control unit (ECU) upgrade for the 4.2 FSI V8. 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 EMCS functionality puts the control of the engine’s operation at your fingertips and allows for additional features and options to be installed to the OEM ECU.
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 across the entire power band. APR’s ECU Upgrade optimizes ignition timing, cam timing, lambda and more to produce higher output!
APR’s ECU Upgrades provides an excellent leap in horsepower and torque while retaining OEM knock control sensitivity and other built in safety features. This results in an exciting and powerful upgrade, optimized for various fuel grades found around the world
The APR Stage I ECU Upgrade gives you higher peak numbers of 458 HP/330 FT-LBS on 93 (R+M)/2 octane and up to 466 HP/335 FT-LBS on 100 (R+M)/2 octane race fuel. As much as 18 HP and 16 FT-LBS of torque are available through the power band!
Gains over Stock
Stage 1 – 93 Octane gas – 458HP / 330 Ft-lbs of Torque = 10 HP Gain over stock / 16 Tq over stock
Stage 1 – 100 Octane gas – 466HP / 335 Ft-lbs of Torque = 18 HP Gain over stock / 16 Tq over stock
Acceleration Enhancements
Beyond horsepower 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, throttle lag commonly noticed at slow speeds and while reapplying throttle has been reduced.
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
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.
