Hey all! I have a 2015 Yukon that I?ve just installed a factory style billet converter in. I followed a video by Matt Sanford on how to tune the factory transmission and it definitely feels better. However, 1-2 upshift is pretty harsh. Does anyone have a good tune that doesn?t have that issue? I?m new to all of this so any help is appreciated!
You forgot to post the tune. This is from a modified suburban with stock trans. I didn't do anything different in the trans that I wouldn't do on a stock truck however.
For some reason it wont upload. Its showing a BTC file and that its unsupported. Can I convert it to a hpt file like yours? Or maybe Im trying to upload the wrong file..
Also, what truck is this tune for? Will it hurt if its loaded into a 2015 year model?Originally Posted by 04silverado6.0
You never just load another tune into a ecm/tcm that is not based on what was read from them ever. Load it as a compare file and copy over whatever you want to use. But even that can be risky if the OS are different or a different MY if you don’t know what you are doing.
