Delicious Tuning Flex Fuel Kit - 2008-2021 STI

Delicious Tuning - Flex Fuel Kit is a complete seamless Flex Fuel solution for your engine management tuning software, whether it be Cobb, EcuTeK or whatever system you choose. Our FlexFuel system determines the content ratio between gasoline and ethanol content in the fuel. It then sends a signal to the ECU which dynamically computes the correct air/fuel ratios, ignition timing values, boost levels, cam angles, traction control and more based on the ethanol content. This kit features an fuel pressure monitoring (optional) and as well as ethanol content through the Delicious Tuning Bluetooth App. Confused about E85 ethanol and Flexfuel? Visit our FAQ. 

IAT Input (option) - All emissions related devices are still 100% operational with our IAT Input Flex Fuel Kit(s) and the intake air temp is still being used as it was intended by the vehicles OEM engine management system. Our IAT Input Flex Fuel Kit(s) supports IAT (Intake Air Temperature) compensation and still measure/send the appropriate temperature signals to the ECU via our module for proper calculation over a broad range of temperatures. Compensation for cold start works as intended as we have implemented custom code in our IAT Input Flex Fuel Kit(s) that is transmitted to the ECU for proper startup on a range of ethanol blends.

FFDS - Flex Fuel Diagnostic System 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. 

DESS - Dynamic Engine Safety System (DESS), you can rest assured that in the event of a fuel pressure loss, your engine will be protected. Our safety system (the only one on the market) will rapidly detune the engine to avoid damage brought on by a sudden fuel pressure loss of the low side fuel pressure pump. This system protects your engine form failure due to a lean condition, thus protecting the engine from possible damage brought on by pre-ignition.
