New ECU / ECU interchangeability?
I've been having some issues with my car starting / running since storing it for the winter, and the shop I've brought it to say the ECU has moisture damage and that is causing the issue. They are willing to try to clean it out, or they've priced out an OEM new ECU for $3500 CAD.
Does anyone have any experience swapping out ECUs? I've found some used ECUs on eBay... some come with immobilizers, some don't. Does a new ECU require new immobilizers? Can I use an ECU from a different year, different body style, different transmission, etc? Any guidance would be appreciated! |

You need to get it synced with the CAS and key from your car, get the VIN written on it and have the mileage zeroed out. I think this involves taking out your CAS and shipping the whole set up to a tuner/coder that can do it.

Interesting. I assume you had to do this for your S65 swap. Can you therefore buy an ECU from any model year and body style, as it has to be coded anyways?

As far as I know there are no differences between MSS60s in the various body styles. |

you can run an rsa bypass on the mss60 and then flash the new vin to a used dme, although there is a company in Pennsylvania that can supply you a replacement dme with warranty.

We can provide a replacement ecu for a fraction of that.

You can 100% trust BPMSport/Mike B to provide you with a fully functional and properly cloned ecu. I’ve had his stage 2 tune on my e92 M3s for a dozen years now and I’ve never encountered even a single issue.
