What each modification does

Stage 1 for Mercedes-Benz C 300e (320 hp): Software-only remap for a car with standard hardware. 320 hp to 353 hp and 700 Nm to 753 Nm.
Stage 2 BASE for Mercedes-Benz C 300e (320 hp): Remap matched to hardware upgrades. Which parts are needed differs per engine. If needed we fine-tune the file up to 3 times free of charge, based on the datalogs you send us.
E85 or other special fuels modification for Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 hp): Faster shift times, modified shift points, raised torque limiters, raised rpm limits and higher clutch pressure where needed.
Pops and bangs for Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for Mercedes-Benz C 300e (320 hp): Selected fault codes are switched off so they are no longer stored or shown.
Start/Stop System Off for Mercedes-Benz C 300e (320 hp): Start-stop is switched off by default.
Cold start off - Catalyst heating off for Mercedes-Benz C 300e (320 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Catalyst off for Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 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 Mercedes-Benz C 300e (320 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
SAI off for Mercedes-Benz C 300e (320 hp): The secondary air injection system is switched off in software.
Torque monitoring off for Mercedes-Benz C 300e (320 hp): Torque monitoring is relaxed so a higher torque does not trigger limp mode.
Readiness ok for Mercedes-Benz C 300e (320 hp): Readiness monitors are set so the car reports ready at an emission inspection.
IMMO_OFF for Mercedes-Benz C 300e (320 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Cloning (ECU/TCU) for Mercedes-Benz C 300e (320 hp): The complete content of one unit is copied to another unit of the same type.
Checksum Correction for Mercedes-Benz C 300e (320 hp): The checksums of the file are recalculated so the control unit accepts the modified software.
