I'm using the same speedo, (91 Suburban)...Maybe I have wrong info on the pulses per mile on the early style electric speedo heads???Originally Posted by pcmcobra
Could someone double check my research???
4000 pulses per mile out of the ECM to the speedo, late model C/K?
2000 pulses per mile out of the DRAC's module to the speedo head, R/V model?
