New on here, but I've been messing with BMW's since my first 518i.
My current one is a £300 328i with a blown engine. I have a non-vanos, non-ews 2.5 M50 to go in and I'm unsure of what to do about the EWS. I have the ECU for the 2.5 included in the sale. I have no idea whether the ignition will look for the ECU, not find it and shut everything down, or whether the ECU will accept whatever the ignition tells it and fire up.
For detail, this is a track car, and security is not an issue. If the simplest method is to ignore the key and immobiliser and fit a row of switches, then that's the method I'll go with.
thanks for any help..!
