What each modification does

Stage 1 for BMW Z4 2.5i (192 hp): Software-only remap for a car with standard hardware. 192 hp to 207 hp and 245 Nm to 257 Nm.
Stage 2 BASE for BMW Z4 2.5i (192 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 BMW Z4 2.5i (192 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 Z4 2.5i (192 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.
Pops and bangs for BMW Z4 2.5i (192 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.
VMAX speedlimit on/off higher/lower for BMW Z4 2.5i (192 hp): The electronic speed limiter is removed, raised or lowered.
DTC off for BMW Z4 2.5i (192 hp): Selected fault codes are switched off so they are no longer stored or shown.
Catalyst off for BMW Z4 2.5i (192 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 BMW Z4 2.5i (192 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
SAI off for BMW Z4 2.5i (192 hp): The secondary air injection system is switched off in software.
IMMO_OFF for BMW Z4 2.5i (192 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Virginize (ECU/TCU) for BMW Z4 2.5i (192 hp): The unit is reset to an unpaired state so it can be coded to another car. A different service from IMMO_OFF.
Cloning (ECU/TCU) for BMW Z4 2.5i (192 hp): The complete content of one unit is copied to another unit of the same type.
Checksum Correction for BMW Z4 2.5i (192 hp): The checksums of the file are recalculated so the control unit accepts the modified software.
