Why switch to E85?

1
💰
Immediate savings

E85 costs roughly half as much as petrol at the pump. At 8L/100km, the yearly saving is over €1,000.

2
⚡
Power gain

RON 108 means more ignition advance is possible. Up to +20% on well-built, properly calibrated turbo engines.

3
🌱
Environmental impact

A plant-derived biofuel. A markedly better carbon footprint than fossil petrol, with no performance sacrifice.

Map Recommended change Zone Criticality Note
Start Of Injection (SOI) +8° to +15° Cold start CRITICAL The single most important point. Prevents 90% of cold stalls.
Injection qty cold start +XX% to +XX% Temp < 40°C CRITICAL Startup enrichment to compensate for E85's low volatility.
Warm-up enrichment +XX% to +XX% Warm-up IMPORTANT A gradual transition between cold start and warm running.
Injection qty full load +XX% to +XX% Full load CRITICAL Mandatory — E85 needs around 30% more fuel.

The workflow Complete

The first two steps are visible. The next five — the most technical — are reserved for the course.

1
SOI + cold start maps

Start with Start Of Injection and Injection Quantity Cold start — the most critical maps, the ones that decide whether the car starts properly from cold.

2
Injection quantity + lambda

Raising full-load injection quantity and adjusting the lambda target. The foundation of engine safety.

3
Warm-up enrichment 🔒 Course

Adapting the warm-up phase for a smooth transition. Prevents hesitation and rough running. Exact values and application ranges included.

4
Ignition advance 🔒 Course

Knowing exactly when and how much to advance ignition on E85 without risking knock. Validation by datalog.

5
Torque and ECU limiters 🔒 Course

Raising the torque limiters and air mass limit to use the available gain without tripping unwanted protections.

6
Flash → datalog → validation 🔒 Course

The full flashing, logging and data analysis protocol. Plus a post-conversion validation checklist.

7
Final adjustments 🔒 Course

Fine-tuning trims, correcting transition zones and optimising ignition from the logs. Iterating until it is fully stable.
