ECM question

[mnbuck6]

Hi All,

The question I have, will a GM E40 ECM (engine computer), service number 12597191 that fits a 2006 GTO's work in my 05 SSR? The Manufacturer Part Number is 12596733 and I plan to send this out to be tuned and swap it out with my factory one. Or if their is another ECM I can use please let me know.

Thanks
Buck

I think I would talk to a Chevy Technician. I looked at the GTO ECM and the SSR ECM Schematics. They are not even close. The SSR Controls many more functions than the GTO. The Electronic Components and extra Data Connections have to be there for you to Re-program. I don't see those functions in the GTO System. Good Luck.

Thanks for the reply. I will give GM a call and get more information.

i did a search on Car-Part.com--Used Auto Parts Market and it listed several for the 2005 SSR
05 vette
04 gran prix
05 GTO
05 trailblazer
05 Ranier

i sent a email to my tuner and asked him if they all use the same ECM and if they would work for tuning
05 Envoy
