APR TT-RS ECU Software UpgradeAPRTTRS
The Audi 2.5 TFSI ECU Upgrade is an expertly recalibrated engine control strategy that remaps boost, timing, air fuel ratios and other engine management paramaters 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. APR's ECU Upgrades are available in octane specific versions to allow you to take full advantage of the fuel quality available in your area. APR's Motorsport Left Foot Braking feature is now available allowing customers more control over their vehicle's throttle. Under normal operation, throttle input is disabled while pressing the accelerator and brake at the same time, however this may be undesirable for those looking to get the most out of their vehicles performance on the track. Enabling the left foot braking feature, the driver will have complete control over the vehicle's throttle and braking system, which may give the edge he or she needs at the track. Stage I & Stage II ECU Upgrade Not only does our Stage I ECU Upgrade give you higher peak numbers of 414 horsepower and 430 ft-lbs of torque, but also gains of up to 73 horsepower and 79 lb-ft are available at lower RPMs! APR's ECU Upgrade is the best power per dollar modification for the new 2.5 TFSI 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. APR Stage I customers are entitled to a free Stage II ECU Upgrade to take full advantage of the APR RSC Turboback Exhaust System. The free flowing APR RSC Exhaust System allows APR's Engineers to safely increase the 2.5 TFSI's output to 430 HP and 464 FT-LBS of torque representing a 99 HP and 113 FT-LBS of torque increase over stock! The APR Stage II ECU Upgrade requires a high flow downpipe and is recommended for use with a full turboback exhaust system.
