Crane Cams Power Tuner Question?

[Sunset T/A]

I bought a Crame Cams Handheld Tuner a couple of years ago for my T/A. I used it a couple of times, so it is VIN locked to my car. I returned my car to stock tune, then had a dyno tune done with LS1 Edit. Can I use this tuner only to read and delete codes, or will it mess something up? Does anyone know the answer for sure? Thanks guys.

yes, you can use it to read/clear DTCs without messing up your tune. you have to go through the initial reading of your PCM and select no through the whole process. then go back and read/clear DTCs. you only have to do the inital reading of the PCM once. after that, you can go directly to read/clear DTCs.
