Good day, I acquired a 1996 Lt1 Corvette Auto, that has been tuned and deleted by the PO. When I got it, I already knew there was issues with the tranny (4L60e). He stated that he hooked up an ODB2 scanner to clear codes, and after that moment, the tranny hasn't up-shifted. Is this possible, or do I just have a burnt tranny? Thanks
Also, I would like to add a larger cam,and HP tuners isn't compatible, what would you recommend in it's place?
Do you have a scan tool and need help? Have you taken it to a professional technician? You might get better help over on www.gearhead-efi.com . Lots of guys over there with obd2 lt1 stuff. I also do lt1 stuff. Where are you located? I might be able to refer you.

They ran a diagnostics on it there.No codes, and it wouldn't take any commands manually, or with the laptop. He reflashed something, but I'm not sure what it was. I'm in a small town called Freer, TX. Thanks

Is it possible to have ruined the tune and shift points, using an OBD2 scanner and deleting codes?
No not possible. There is always the option to put a 94-95 OBD1 computer in it and tune it with relatively cheap tuners and cables that are available. Jet DST is rebranded Tunercat OBD2 after the Tunercat owner sold it to them. Their customer support is pretty non existent if you have any problems with it which almost everyone that uses it complains about now. You need to either find someone that has the original Tunercat OBD2 tuner or do the ODB1 downgrade. You will lose some functions like misfire detection and no after cat monitoring. May lose some other thing being it's a Vette as about everyone I know that has done the OBD1 swap has been a F-Body.
This is a good forum for that platform and help with the OBD1 swap.

Someone would have to download the tune, edit it, and reload it up. It would take a minimum of 5-10 minutes. A hand held scanner can't do this.
