Used ECM and new EWS?
I put a new motor in my 740il, and a good used junkyard ecm, car cranks finally with used ecm, but i have no spark, i was wondering if i can just put a brand new EWS module in the car, and align it with the ECM, and not have to replace the key or anything else. I am 100% sure that the EWS module is not coded to the ECM as it is a used junkyard ECM. i do have codes in the ecm for ews antitheft.
All i need to know is if i can put a new ews4 module in the car, and code and align it to the good used ecm i currently have in the car, any help would be awesome!
thanks so much!
