I have a 99 pcm, in my 99 Camaro. I've got a RR sitting here and a v1.2 efi.
First I read the pcm with the flashscan and save that file on my laptop correct. Then it says its best to upgrade the pcm to an 02 op system and then even a custom op system.
So do I connect the RR and upgrade it to a 02 system and then how do I import the data from the file I saved onto the RR ? Or do I upgrade the op system with the tune file already loaded on the RR? In other words read the pcm and then flash that over to the RR and then upgrade the op system on the RR?
Chomping at the bit here...
