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 −46%

Petrol · 100 km

~~5.8 L~~ · €12.16

E85 · 100 km

7.2 L · €6.51

You save ≈ €5.65 every 100 km — about €848 a year (over 15 000 km)

E85 uses ≈ +23% more litres, but the pump price (€0.905/L vs €2.085/L, France average on November 4, 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.

+20 hp and €848/year saved — both
