I have a u7194 with 9r29 which I use with my '09 Sierra with the 6.2. I recently went in for some service work and they reflashed my ECM and the configuration is no longer recognized. Is there a new tune to support the new ECM software from GM that's more recent than 9r29?

Thanks.

allow the tool to save a copy of the new stock tune, then export it and post it here or email it to us so we can add it for you.

Thanks

I just noticed the post below which somebody had exactly the same problem with a 2012 and 9t30 was posted... I'm guessing I can use the same one that was posted for him?

Apparently mine must still read differently. Tried that one (9t30q) and got the same unrecognized configuration error. I'll upload a copy of my backup tonight and post it to this thread.

Original backup of the new software is attached. Let me know if you need further info. Thank you for the assistance.

here you go, restore the stock tune then update to this.

My '09 Tahoe has the same problem. It went to the dealer, now the cal is no longer recognized. It took a lot of back and forth loading to get the truck running again. Wouldnt start at all. I have upgraded to the r29 update already. What is the deal? Will the above program work on my Tahoe?

Im gonna need a different tune. That one didnt work. I hand wrote the numbers for the current tune. Do you want me to post those 126***** numbers or do you need the tune exported? It is my dad's truck, so I dont want to hang it up. Thanks. Hope everyone has a great Easter. 5.3 motor btw.

OK, I downloaded the stock backup. Thanks.

sorry for the delay, here you go.

Restore the stock tune, then update to the attached revision, your vehicle will be supported.

Thanks
