Help with '85 Corvette '870 ECM

[Craig Marcho]

Well, i'm aware of the swap to the '160, but what I'm looking for is more
along the lines of what parameters to change in the EPROM based on the mods
I've done to my car....

I really don't want to swap ECM's yet, I've done enough work on the car
recently, and I'd like to play around with what I've got. Also, I'm still
looking for an ecu file for the corvette 870 ECM.

What kinds of things do I change to make this car run better with that cam
and injectors?

Thanks for the help!
