okay, I just bought a 2005 corvette stuck in limp mode that i trouble-shooted needing pcm.
I was able to extract a read from that pcm. I was not ablt to find a used pcm, so I ordered one from gm.
only available as refurbished. I wasn't sure my read tune was corrupt so I paid gm to install pcm
and load it with any updates.at pick up they said they had a hard time programming. (without any details).
two weeks later I try and read the tune to modify it, and I get the security lockout from to many read attempts.
briefly before that I saw a flash of invalid key or something to that effect.
I don't know if this means its tunerlocked, or if theres a different problem.
im not sure I want to try and full write my car unless that's exactly what one is suppose to do....
I have never seen this message before/ but I see its common when I search.
bottom line is I don't have to tune it, but I would like to...its a stock wifemobile so no parts are on it.
I am using 2.24.188
whats the best advice moving forward?????????????????
what additional info does HPT need to be able to help ,e?
