E85 or other special fuels modification for Cupra Leon 1.5 e-TSI (150 hp)

05/2024

What E85 or other special fuels modification does

The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.

What we change in the calibration

Fuel quantityEthanol carries less energy per litre than petrol, so the injected quantity is raised over the whole map.

Ignition timingTiming is set for the higher octane rating of E85.

Cold start and warm-upStart and warm-up enrichment are adapted, because ethanol vaporises less easily in a cold engine.

Mixture controlLambda targets and fuel trim limits are set for the new fuel.

Good to know

For this engine: E85 conversion at stock power, no power gain.
The file is made for one fuel. The car does not switch between petrol and E85 by itself.
The injectors and the fuel pump must be able to deliver the extra fuel.
