Delicious Tuning STI FLEX FUEL KIT MK2 FOR COBB 04-05 STI / 06 WRX
PN: DT_DIT_COBB_MK2, T_COBB_MK2
Delicious Tuning - FlexFuel BlueTooth Mk2 Kit takes all the guess work out of determining what the ethanol/gasoline (petrol) ratio is in your vehicle. 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.

Frequently Asked Questions:
What is the difference between E85 and FlexFuel? I thought they were the same thing…
- E85 is certain concentration of fuel, being between 68-85% ethanol and the remaining portion gasoline legally. So when you fill up you do not know exactly what you are getting.
- FlexFuel informs the ECU (engine control unit) through unique sensors and electronics added to the vehicle to measure the actual content of Ethanol. Knowing the content allows the ECU to determine proper start up enrichment, fueling, timing, boost and cam control.
Isn’t this the same thing as switching between different tunes provided by a professional tuner?
- No, it is not the same. With just E85 and 91 octane tunes, you may receive a very good tune based on that exact ethanol content it was tuned for. What happens when you need to fill up with 91 octane on a road trip? What is you were tuned for E85 but the pump you filled from changed to E68 for the winter blend? What is your ethanol content and what tune do you use?
So Delicious Tuning FlexFuel allows me to fill up with any quantity of petrol and/or ethanol?
- Yes, with FlexFuel all the guessing is gone, just fill up and go.
How hard is it to install the Delicious Tuning FlexFuel BlueTooth Kit?
- The Delicious Tuning FlexFuel kit is as easy opening the hood to your engine, disconnecting two fuel lines with the provided tool, disconnecting one sensor, installing our own mounting bracket and plugging the new connections into your vehicle. The total install time should take no longer than 20-30 minutes.
Do I need to cut/splice/solder, or tamper with any of the OEM wires or hoses in the vehicle?
- No. Our specific kit is designed to plug into you factory harness and factory fuel lines, along with proper mounting brackets that make for an OEM look, feel and finish. No need to run wires through the firewall, no need to lift the vehicle. Just pop your hood, plug in and go.
Can my vehicle be returned to stock by simply removing the system?
- Yes, your vehicle can be returned to completely stock by removing our installation package. No wires are spliced no hoses cut, remove our mounting bracket, just unplug our system and plug your OEM system back in.
Do I need anything else besides the Delicious Tuning FlexFuel Kit to run E85?
- Yes, you will need the EcuTeK Pro ECU Kit and FlexFuel Tune from an EcuTeK Pro Tuner (such as ourselves) and a vehicle that is supported by EcuTeK FlexFuel RaceROM features.

Do I need two tunes with FlexFuel, one for E85 and one for gasoline (petrol)?
- No, you only need one tune for our FlexFuel package. Our tunes are designed to determine the proper engine parameters based on the ethanol content of the fuel. Reflash your vehicle with our tune, pump in whatever fuel you choose and go.
Why do I need to retune my OEM engine management?
- Delicious Tuning implements additional custom designed tables into the stock engine management system to properly adjust for optimal air/fuel ratios, ignition timing values, boost levels, cam angles, traction control and much more based on the actual ethanol content.
What is the benefit of Ethanol?
- Higher equivalent octane rating of 105
- Cleaner burning fuel, for cleaner emissions
- Cools the engine quickly, great for hot climates
What are the drawbacks of Ethanol?
- Fuel economy will drop about 30-35% with a blend of pure E85
- You will need the ability to retune the OEM engine management system in the vehicle.
- Cold climate starting will be harder due to poor atomization properties of ethanol.
Can I run my own mix of on an E85 tune (not FlexFuel), such as E50?
- A tuned designed around an E85 mix but run on an equivalent E50 mix can cause the ignition timing values to be aggressively high which can cause pre-detonation or ignition knock.
- In some vehicles where the ECU is limited by the range air/fuel adaption will run rich and cause the car to stumble and run poorly throughout the power band and drivability.
How would I have an E50 (or similar) ratio mix in my tank after filling up?
- If you were switching from gasoline (91 octane) to E85 and you were not empty there is a good possibility the ethanol content mix would equate to an E50 (or similar) mix.
How do I view the ethanol content with the Delicious Tuning FlexFuel BlueTooth Kit?
- Download our Android (or IPhone) application and connect to the Delicious Tuning FFBT unit to view your ethanol content.
