Basically, I just have a relay for each that activates the different RPM values.
However, I also had to add an additional relay to latch the staging RPM so that it would only operate during launching and not during any additional shifts. Otherwise, the car tends to backfire between shifts in a 5-speed car.  |
Well I guess I will have to dig the other MSD box out of the building. 
Now do a write up on the particulars......
