Map Modifications

Map modifications are the very core of the tuning process. Depending on the type of the tune and the fuel the engine uses, there are a number of possibilities.

These are the maps that are are most commonly changed in a tuning file

Diesel tuning file map modifications:

For diesel engines we modify the following maps in the ECU

• Throttle response
• Smoke limiters
• Temperature limiters
• Lambda
• Torque limiters
• Start of injection
• Injection duration
• Newton meter conversion
• Turbo pressure
• Turbo system duty cycle
• Turbo limiters
• Rail pressure
• Rail pressure limiters
• Gearbox limiters
• Gearbox shift time (optional)
• EGR function delete (optional)
• DPF function delete (optional)
• Speed limiter (optional)

Petrol tuning file map modifications:

For petrol/gasoline engines we modify the following maps in the ECU

• Throttle response
• Temperature limiters
• Lambda request
• Lambda component protection
• Torque limiters
• Ignition timing
• Camshaft timing
• Requested air load
• Wastegate duty cycle
• Wastegate duty cycle linearisation
• Wastegate duty cycle limit
• Max air load
• Rail pressure
• Rail pressure limiters
• Gearbox limiters
• Gearbox shift time (optional)
• Knock threshold
• Lambda/O2 sensor delete (optional)
• Speed limiter
• MAF scaling (Stage 3)
• Injector sizing (Stage 3)
• Max air load
• Rail pressure
• Rail pressure limiters
• Gearbox limiters
• Gearbox shift time (optional)
• Knock threshold
• Lambda/O2 sensor delete (optional)
• Speed limiter (optional)
• MAF scaling (Stage 3)
• Injector sizing (Stage 3)
