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

The Mk2 can use 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 Presure 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.

- Delicious Tuning FlexFuel Ethanol Content Analyzer with Integrated BlueTooth
- Delicious Tuning Smart Phone Applications (Android or iPhone Compatible)
- Delicious Tuning Hand Assembled and Pressure Tested Fuel Lines
- Delicious Tuning Mounting Bracket and Hardware

Love them!
Size: 7 Slim, Color: Washed Blue
I did but expect these jeans to fit so well and look so nice on my daughter. Hands down the best jeans I’ve purchased for her, much better fit and quality than the other stores! The length is perfect, but it’s a little snug in the waist. Still a great fit with some stretchiness! Great value!

Great pair of Jean and great price!
Size: 14, Color: Washed Blue, Size: 14, Color: Washed Blue
I can’t believe these were only $13. They feel and look like quality jeans, very basic/simple boot cut. My daughter says they’re stretchy and comfortable. I ordered her a size 14 (12’s fit her waist but are always too short) She’s 11 years old, 5’ tall, about 80lbs. The waist adjusters were great for the perfect fit.

Amazing jeans! My daughter loves them!
Size: 7 Slim, Color: Washed Blue, Size: 7 Slim, Color: Washed Blue
My daughter is really slim but tall. She is 7 about 50 pounds. She loves them and I’m so happy because all the other jeans that I buy I have to return cuz they are all too big on her. The jeans are stretchy and feel much more expensive for the price! Great quality! I will be ordering more for sure!
