APR is pleased to present the ultimate ECU Upgrade for the Audi S6 and S7 4.0 TFSI V8!
After months of 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 4.0 TFSI V8 ECU Upgrade is an expertly recalibrated engine control strategy that primarily remaps the engine’s operating parameters, within the factory 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’s patented EMCS functionality puts the control of your engine’s operation at your fingertips and allows for additional features and options to be installed to your OEM ECU.
APR Stage I ECU Upgrade
The APR Stage I ECU Upgrade gives you higher peak numbers of 560 HP/580 FT-LBS on 93 (R+M)/2 octane and up to 569 HP/605 FT-LBS on 100 (R+M)/2 octane race fuel. As much as 124 HP and 163 FT-LBS of torque are available through the power band! APR’s ECU Upgrade is the best power per dollar modification for the new 4.0 TFSI V8 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.
