E85 adaptation (no Stage 1)

Just the fuel switch: the ECU is adapted to run Superéthanol E85 (up to 85% bio-ethanol) with no Stage 1 chip on top. You get a small power bump from ethanol's higher octane (~104 RON) and a much cheaper fill-up. Flex Fuel file: the car still runs on regular petrol whenever you want.

Fuel cost — E85 vs petrol −47%

Petrol · 100 km

~~23.3 L~~ · €50.59

E85 · 100 km

29.2 L · €26.7

You save ≈ €23.89 every 100 km — about €3 583 a year (over 15 000 km)

E85 uses ≈ +25% more litres, but the pump price (€0.914/L vs €2.168/L, France average on October 13, 2026) more than makes up for it.

E85 + Stage 1 remap

Chip tuning re-optimised for Superéthanol E85: the ignition and boost maps are calibrated to make full use of ethanol's higher octane (~104 RON). Bigger power and torque gains than either Stage 1 on petrol or E85 adaptation alone, plus the same cheap fill-up.

+50 hp and €3 583/year saved — both
