Mein Auto: 98 740il
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!
nate

No...because EWS uses multiple components...and all have the same ISN (individual serial number) burnt into them. The DME/ECU, EWS control module, transmitter/receiver (on early EWS II models), and the key. They all have to have the same ISN...if not, the starter, ignition, and fuel will be affected.
