Info ecu Bosch 402

Post by Giovanni »

hello everyone, I would need some information, do the Bosch 402 control units have the same file between M50B25 and M50B20? can they be used on both motors or do you have to change chips? thank you

you can use them if you wanna test
but the B25 and b20 software "tune" are different , so you better use the correct chip for your engine
