Chevy Traverse... E67?... locked ECM? trouble reading

[ericdrob67]

Hi Folks, Just picked up my new 2010 Chevy Traverse. Same 3.6 liter(listed as a supported engine) used in Outlooks, Acadias and i believe in the CTS, G6 and couple others too. I cant get it to read from the vehicle. Did they change ECM's from 07 and 08 to the '10? Is there some trick? I dont remember having the least bit of trouble reading my LBZ/allison when i got that.

Thanks, Eric

Sorry to say but GM did a bit of ECM swapping on the 3.6L, yours is probably fitted with the Bosch ECM, not the E67.
If it's the direct injection engine then it's Bosch for sure, which also means no support, none planned either.

Im guessing the "new" ECM i prolly have isnt supported yet? Does anyone know if there are any tuning options for this year engine?

Thanks, Eric

This was all I was able to get from just connecting to my 2010 AWD Traverse:

ECM Calibration IDs: 12636356 12637011 12637013 12637014
ECM OS ID: 825374259

Is there anyway that we can help with support for 2009-2011 models?

That is 99% certain to be the Bosch ECM. Thanks for the offer to help but it'll probably never happen.

You are correct. It says BOSCH clear on the ECM itself.

It looks like we will be going to step 2 for this vehicle; Seeing if we can get do a 12651994 ECM (2012 model) and necessary wiring swap.
