What each modification does

Stage 1 for BMW M3 M3 Competition (510 hp): Software-only remap for a car with standard hardware. 510 hp to 610 hp and 650 Nm to 800 Nm.
Stage 2 BASE for BMW M3 M3 Competition (510 hp): Remap matched to hardware upgrades. Which parts are needed differs per engine. 510 hp to 683 hp and 650 Nm to 853 Nm.
Stage 3 BASE for BMW M3 M3 Competition (510 hp): Remap for a larger or hybrid turbo with supporting hardware.
E85 or other special fuels modification for BMW M3 M3 Competition (510 hp): The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.
Flex fuel mod for E85 or other fuel types for BMW M3 M3 Competition (510 hp): The engine adapts to the fuel that is in the tank, from petrol to E85 and any blend in between. This is not a fixed E85 calibration.
Gearbox TCU tuning for BMW M3 M3 Competition (510 hp): Faster shift times, modified shift points, raised torque limiters, raised rpm limits and higher clutch pressure where needed.
Pops and bangs for BMW M3 M3 Competition (510 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 BMW M3 M3 Competition (510 hp): Ignition is cut at the limiter instead of fuel being reduced early, so full power is available to the redline.
Sport displays calibration for BMW M3 M3 Competition (510 hp): The power and torque displays are recalibrated to the tuned values.
VMAX speedlimit on/off higher/lower for BMW M3 M3 Competition (510 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for BMW M3 M3 Competition (510 hp): Selected fault codes are switched off so they are no longer stored or shown.
Start/Stop System Off for BMW M3 M3 Competition (510 hp): Start-stop is switched off by default.
Cold start off - Catalyst heating off for BMW M3 M3 Competition (510 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for BMW M3 M3 Competition (510 hp): Exhaust valves can be opened or closed independent of the driving mode. For cars with valves in the original exhaust.
Catalyst off for BMW M3 M3 Competition (510 hp): Catalyst monitoring by the lambda (O2) sensor is switched off so a sport catalyst or decat does not raise fault codes.
DPF/OPF/GPF off for BMW M3 M3 Competition (510 hp): The particulate filter function (diesel DPF, petrol OPF/GPF) is switched off in software. The filter has to be removed physically first.
EVAP off for BMW M3 M3 Competition (510 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
AGS off for BMW M3 M3 Competition (510 hp): The active grille shutters are switched off in software.
Torque monitoring off for BMW M3 M3 Competition (510 hp): Torque monitoring is relaxed so a higher torque does not trigger limp mode.
Readiness ok for BMW M3 M3 Competition (510 hp): Readiness monitors are set so the car reports ready at an emission inspection.
IMMO_OFF for BMW M3 M3 Competition (510 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Cloning (ECU/TCU) for BMW M3 M3 Competition (510 hp): The complete content of one unit is copied to another unit of the same type.
Checksum Correction for BMW M3 M3 Competition (510 hp): The checksums of the file are recalculated so the control unit accepts the modified software.
