Detailed Explanation of Map Groups
Driver Wish Map
- Purpose: Pedal → torque request
- Units: Nm
- Axes: Pedal %, RPM
- Remap: Increase mid-pedal torque slope
- Safe Limit: +10–15%
- Effect: Faster throttle response
- Risk: Driveline stress
Torque Limiter Maps
- Purpose: Max torque
- Units: Nm
- Axes: RPM / Gear
- Remap: Raise slightly above driver wish
- Safe Limit: +15%
- Effect: Allows higher boost
- Risk: Clutch slip
Boost Target Map
- Purpose: Turbo pressure command
- Units: mbar absolute
- Axes: RPM / Load
- Remap: Increase high-load cells
- Safe Limit: +150–200 mbar
- Effect: More airflow & power
- Risk: Turbo overspeed
Wastegate Duty Map
- Purpose: Turbo actuator control
- Units: %
- Axes: RPM / Load
- Remap: Adjust for stable boost
- Safe Limit: +10%
- Effect: Consistent turbo control
- Risk: Boost oscillation
Lambda Target Map
- Purpose: AFR command
- Units: Lambda
- Axes: RPM / Load
- Remap: Slight enrichment under load
- Safe Limit: 0.78–0.82 λ
- Effect: Knock safety
- Risk: Fuel consumption
Ignition Timing Map
- Purpose: Spark advance
- Units: Degrees BTDC
- Axes: RPM / Load
- Remap: Advance mid-load
- Safe Limit: +2–3°
- Effect: Torque gain
- Risk: Knock
Knock Sensitivity Maps
- Purpose: Knock correction
- Units: Gain factor
- Axes: RPM / Load
- Remap: Slight reduction
- Safe Limit: −5%
- Effect: Less timing pull
- Risk: Engine knock
Fuel Enrichment Maps
- Purpose: Extra fuel under boost
- Units: Multiplier
- Axes: RPM / Load
- Remap: Increase high-load fueling
- Safe Limit: +5–8%
- Effect: EGT control
- Risk: Excess fuel
Axes Explanation in Magneti Marelli ECU
Common axes:
- Engine speed (RPM)
- Load or cylinder air mass
- Pedal position
- Calculated torque
Correct axis interpretation is crucial, as Magneti Marelli often stores axes in non-linear, manufacturer-specific formats.
Remap Strategy Order (Schiller Method)
- Driver Wish
- Torque Limiters
- Boost Target
- Wastegate Duty
- Lambda Target
- Ignition Timing
- Knock Sensitivity
- Fuel Enrichment
This ensures torque model integrity and safe turbo operation.
Safe Petrol Tuning Limits – Alfa Romeo Giulia
- Boost: +0.15–0.2 bar
- Torque: +15%
- Ignition: +2–3°
- Lambda: 0.78–0.82
Effects of Map Changes
- More Boost: ↑ power, ↑ EGT, ↑ turbo stress
- More Ignition: ↑ torque, ↑ knock risk
- Richer Lambda: ↓ combustion temp, ↑ fuel use
- Higher Torque: ↑ acceleration, ↑ drivetrain load
