The carbureted engine car will require a different ECM and PROM/MEMCAL. The TPI car should not require any calibration change, so long as you select the correct gears for the speedometer drive so the VSS outputs 4,000 pulses per mile.

 

- sorry this is kinda off topic - Vader, how do you figure out the amount of pulses you need for a speedo? as in my 85 mph speedo(in my blazer) is 15mph off...
