i have the car running good but the tach speedometer and fuel guages are all off. im not sure what i need to change to make it work. i am using the original 6 speed that came in the car, anyone that has done this before lease point me in the right direction. thank you
Is the tach showing either half or double (can't remember which) of what you suspect the actual rpms are? There is a tach pulse in the tune that must be changed for the tach to correct itself since the two tachs read a different number of pulses per rpm. The speedo, you'll have to factor for correct gear ratio and tire size. The fuel gauge (depending on the year of the car) may be independent of the PCM.

Yes the tach and speedometer reads exactly half the actual mph. Can you tell me what I need to set the tach pulse to, to double it?
your tune is locked
