Rewired my 98 Z28 to use 99+ RR PCM and COS5
I finished the wiring last night. I can get the laptop to connect to the car for scan, and i can connect to the roadrunner. When I try to upload a .cal file for COS5 by selecting "upload operating system" on the roadrunner screen, I get an EFIlive registration error. Tried everything, no luck. Says it everytime I open the software too.
Anyways, when I get that straightened out, do i just upload the COS5 how I stated earlier? Then fire the car up? I'm a little lost, getting this going for the first time.
Thanks
Matt
