New Product Alert: IE releases TrueFlex Software for 2015-2017 Golf R & S3!

September, 16th 2021

IE is proud to release it’s TrueFlex tuning solution for early model VW MK7 Golf R and Audi 8V S3 2.0T MQB engines. TrueFlex is a performance based flex-fuel ECU tune that adjusts for ethanol and pump gas mixtures in real-time. This allows the end user to fill up with 91/93 octane all the way up to E85 and the TrueFlex calibration will automatically adjust for any percentage. This results in impressive power gains, easy fill-ups, and added safety for your vehicle.

WHY RUN ETHANOL ON YOUR R OR S3?

E85 fuel unlocks massive performance potential as it contains tons of oxygen, burns cooler, and has a high resistance to knock. This provides more horsepower and torque than running conventional gasoline and is more readily available (in most states) and less expensive than race gas. TrueFlex is a performance flex-fuel calibration that maximizes power instantly and in real-time delivering up to 435HP and 457ft-lbs on full E85!

RELIABLE ETHANOL

TrueFlex's ability to accurately meter and adjust for ethanol content allows the tune to instantly alter the ECU maps to keep the engine in the optimal range as the fuel hits the injectors. This offers amazing protection from pumps that may have lower than advertised ethanol content or if no ethanol is available. Fill up with the fuel available to you, and let TrueFlex do the rest!

LEADING FEATURES

Reflashing the ECU for fuel content is a thing of the past.
HPFP upgrade is the only fuel system modification required
TrueFlex adjusts boost and timing when the fuel mixture changes. The stock engine computer does contain code to adjust fueling based on the ethanol content; we enabled this feature and utilized it to control fueling, but we also developed custom code to control boost and ignition timing, allowing the tune to be optimized at every mixture of ethanol and ambient conditions.

IE TrueFlex wiring harness with ethanol sensor

IE DSG Tune Note: IE MQB DSG Tunes are written to work with TrueFlex torque output
