Hi,

I have BMW 2 F22 M235iX Coupe from USA. This car have speed limit 210km / h
The car is currently in Europe and the customer wants to change the speed limit at 250km / h
When I encoding the ECU by E-sys I can't change the vmax.

From the ETK the ECU is MEVD172G, can autohex reset working hours in this model ?
Will I be able to code the ECU with another VMAX if I reset the working hours and is it enough or does something else have to be changed ?

regards,
Mati

Reset the hours and coding the vmax should be good enough.

First I backup with advance option.
Second I read ECU and it show vin, isn and working hours.
Then I changed working hours to 0 and write.
Read again and it was 0.

After connecting ECU to car and I read working hours with ISTA D and it show old value 83000min (ista show minues, autohex show hours)
It is possible that working hours are in several places and autohex cant find all of it ?
