COBB Volkswagen Stage 1 + Flex Fuel Power Package WITH DSG / S Tronic Flashing (MK7/MK7.5) GTI, Jetta (A7) GLI, AUDI A3 (8V)

Our COBB Tuning Flex Fuel Upgrade Kit for VW/Audi measures the ethanol content level of the fuel being pumped into your engine and then sends that data to the ECU to be used in a Flex Fuel calibration.

The Accessport is the world's best selling, most flexible, and easiest to use ECU upgrade solution for your Volkswagen or Audi. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It's the last engine management solution you'll ever need. Not Compatible with GPF equipped vehicles or vehicles equipped with a MAF sensor.
