any thoughts- i am sure i've been through this before, won't let me access tune on read (bolt-ons) changed to cam/ heads and brought to me for tune. I have unchecked high speed & check try alt keys. I "believe" the tune was not locked, but it was an HP cal. Do I flash in stock tune and start over (with tech II) or can I read it somehow???
thanks
Does it actually read the PCM then fail, or fail right at the start?
If it's a pptuner COS then you won't be able to read it.
I think it will be locked automatically if it is a pptuner COS as well.
does not read it.. kicks me out immediately.
Hp locks their tunes if you load one of their Custom OS's into your ECM. It can be unlocked. I have unlocked a few of these...
