While at cruising speeds (30mph-40mph) when running E85 (76% on the gauge) the engine has a hesitation that occurs every 10-15 seconds. The hesitation happens while simply maintaining speed, not accelerating, nor coasting.
Mods are;
- Takeda Intake
- PRL Cat'd downpipe
+ Oxygen sensor disabled
- Innovate Ethanol Sensor
- Flex Fuel Tune.
Any thoughts or advice?

Re: Flex Fuel - E85 Hesitation
You must post the calibration as well as a datalog showing the issue.
