[QUOTE="IUP99snake, post: 13047570, member: 7060"] Yea, it needs to be set on .5 pulses per revolution because there is 1 firing stroke every 2 revolutions (on a 4 stroke engine). I can't think of any reason why a fuel injector wouldn't be an accurate tach signal for the gauge... I've checked the tach display on the software compared to the diagnostic tach feature on my odometer and it's pretty damn close. The only discrepancy I can notice is with the software. If anyone can tell me a better place to hook up the tach input, I'm all ears. You could always get a standard tach adapter and use that.. Or get an MSD box with timing retard and a tach output and that would kill two birds with one stone.. You'd get the most accurate RPM input and you'd be able to use the failsafe wire to pull timing. I've been having problems with the CCRM powering my fuel pump lately... I think I'm gonna use the failsafe wire to power a relay in order to supply extra power to the fuel pump if the pressure gets too low. (I know, a new CCRM would also fix the problem). [/QUOTE]
