E85 or other special fuels modification for Audi RS4 RS4 4.2 V8 (420 hp): The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.
Pops and bangs for Audi RS4 RS4 4.2 V8 (420 hp): Fuel still injected on overrun ignites in the exhaust and gives the crackle sound. Intensity can be set: soft (burbles), normal, hard or flames.
Hardcut limiter for Audi RS4 RS4 4.2 V8 (420 hp): Ignition is cut at the limiter instead of fuel being reduced early, so full power is available to the redline.
VMAX speedlimit on/off higher/lower for Audi RS4 RS4 4.2 V8 (420 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Audi RS4 RS4 4.2 V8 (420 hp): Selected fault codes are switched off so they are no longer stored or shown.
Start/Stop System Off for Audi RS4 RS4 4.2 V8 (420 hp): Start-stop is switched off by default.
Cold start off - Catalyst heating off for Audi RS4 RS4 4.2 V8 (420 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for Audi RS4 RS4 4.2 V8 (420 hp): Exhaust valves can be opened or closed independent of the driving mode. For cars with valves in the original exhaust.
Catalyst off for Audi RS4 RS4 4.2 V8 (420 hp): Catalyst monitoring by the lambda (O2) sensor is switched off so a sport catalyst or decat does not raise fault codes.
EVAP off for Audi RS4 RS4 4.2 V8 (420 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
SAI off for Audi RS4 RS4 4.2 V8 (420 hp): The secondary air injection system is switched off in software.
Boost Sensor Calibration for Audi RS4 RS4 4.2 V8 (420 hp): Calibration for an uprated boost pressure (MAP) sensor.
RPM Limit Mod for Audi RS4 RS4 4.2 V8 (420 hp): The engine speed limit is raised or lowered.
IMMO_OFF for Audi RS4 RS4 4.2 V8 (420 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Cloning (ECU/TCU) for Audi RS4 RS4 4.2 V8 (420 hp): The complete content of one unit is copied to another unit of the same type.
Anti lag for Audi RS4 RS4 4.2 V8 (420 hp): Boost is kept up when you lift off the throttle, so the turbo responds sooner when you accelerate again.
