What each modification does

Stage 1 for BMW X4 28i (258 hp): Software-only remap for a car with standard hardware. 258 hp to 279 hp and 310 Nm to 414 Nm.
Stage 2 BASE for BMW X4 28i (258 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. 258 hp to 288 hp and 310 Nm to 414 Nm.
E85 or other special fuels modification for BMW X4 28i (258 hp): The calibration is set up for one special fuel, for example E85. This is not a flex-fuel setup.
Pops and bangs for BMW X4 28i (258 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 X4 28i (258 hp): The electronic speed limiter is removed, raised or lowered.
Kickdown off for BMW X4 28i (258 hp): The automatic downshift at full throttle in manual mode is switched off.
DTC off for BMW X4 28i (258 hp): Selected fault codes are switched off so they are no longer stored or shown.
Cold start off - Catalyst heating off for BMW X4 28i (258 hp): The catalyst-heating phase after a cold start (raised idle, retarded ignition) is removed.
Exhaust flap control/off for BMW X4 28i (258 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 X4 28i (258 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 X4 28i (258 hp): Monitoring of the fuel vapour (EVAP) system is switched off.
AGS off for BMW X4 28i (258 hp): The active grille shutters are switched off in software.
Torque monitoring off for BMW X4 28i (258 hp): Torque monitoring is relaxed so a higher torque does not trigger limp mode.
Readiness ok for BMW X4 28i (258 hp): Readiness monitors are set so the car reports ready at an emission inspection.
Boost Sensor Calibration for BMW X4 28i (258 hp): Calibration for an uprated boost pressure (MAP) sensor.
IMMO_OFF for BMW X4 28i (258 hp): The immobiliser check is removed from the ECU, so the engine starts without the immobiliser.
Cloning (ECU/TCU) for BMW X4 28i (258 hp): The complete content of one unit is copied to another unit of the same type.
