I saw in your signature that you have RS steering on your Sonic. Is this a software flash?
I have a 2017 LT.

You're right, it's not the Tech-II but a computer based program that GM uses now. Thank you very much!

I had a question about the RS steering program. Is it just a flashing from a Tech-II? is there a hardware difference?

Thanks for your time!
