Hello,
I am trying to tune a 98 Camaro and cannot get passed the Security access denied screen during a read entire. I have been told that this vehicle has a 1999 pcm (installed at another shop). How do I get passed this? Is it an issue that the VIN does not jive with the PCM? Also in the write entire screen there is no OS # nor a TCM OS#. I have access to a Tech 2 and could do a dealer reflash if that would help but do I reflash to a 99 VIN or his current? Also, If I have another licensed 99 file could I perform a write entire and start from scratch? Thanks in advance!!!
