About the BMW X7 xDrive40i G07
The BMW X7 xDrive40i is the six-cylinder petrol model of the G07 X7. It uses the B58B30M1, the updated version of the B58 inline-six, fitted from 12/2018 production.
Because the B58B30M1 belongs to BMW’s revised B58TU generation, it should be identified separately from first-generation B58 engines. Exact ECU hardware and software should be confirmed from the vehicle before a calibration file is prepared, together with the transmission software level.
For an X7 request, please send the build date, current DME software, fuel grade, transmission details and a list of any modifications. If the vehicle has been tuned before, tell us which software was used and supply the original file if you have it.
