E85 · 98 · Any Blend
Flex Fuel
E85 Tuning
Fill up with E85, 98 or a mix of both — a sensor reads the ethanol content and the calibration adjusts timing, boost and fuelling on the fly. It's the most effective upgrade we fit to turbo cars.
More power
Ethanol resists knock, so the tune can run more timing and boost safely.
Any blend
No switching maps — the car adapts to whatever is in the tank.
Runs cooler
Ethanol's cooling effect lowers intake and combustion temperatures.
Freedom to fill
No E85 nearby? Fill with 98 and drive normally.
The Process
How flex fuel works
- 01
Fuel system check
We check your pump and injectors so the setup is matched to your car and power goal.
- 02
Hardware fitted
An ethanol content sensor is installed, plus any fuel system upgrades your power goal needs.
- 03
Calibrated on the dyno
We tune across the ethanol range on our Mainline dyno so every blend is safe and strong.
What's Involved
What a flex fuel setup includes
Ethanol content sensor

Fuel system upgrades
Low and high-pressure pump and injector upgrades where needed.
Custom calibration
Timing, boost, fuelling and cold-start blended across E0 to E85.
Datalog review
Logs checked on the dyno and road to confirm fuel trims and knock control.
