Delicious Tuning



Flex Fuel Signal Input
Intercooler Type

Delicious Tuning - Mk2 Flex Fuel Kit is a complete seamless solution for your Cobb Accessport V3, that any Cobb Protuner can tune. It features all the same functionality as Cobb's standard flex fuel kit, but with a few extra features and functionality.

The Mk2 can use either TGV or O2 sensor inputs (built to order), to get the ethanol content or fuel pressure signals to the ECU. Please select which input you desire from the drop down menu.

With the Bluetooth feature, you can now monitor your fuel pressure, fuel temp for starting, as well as ethanol content. These parameters can also be displayed via the Accessport display.

Flex Fuel Diagnostic System (FFDS) that can detect electrical opens, electrical shorts, sensor failures or even too much water within the fuel.   The fault detection can diagnose an open in the electrical system, short, bad ethanol sensor, too much water in the fuel system, and fuel pressure loss. 

Fuel Pressure System (FPS) will display and dynamically control injector opening time to finely adjust fueling and open in the event of fuel pressure loss.

The included Stumble Fix Kit eliminates the infamous 2800 to 3200 RPM stumble that occurs on 08-16 STi's by eliminating fuel pressure regulator buffeting, through using a more stable vacuum source and specific tuning strategies.
