I cant seem to figure out why my speedo isnt working right. I've played with many variable combinations, and for some combos I get a max speed reading of 5. I'm sure I'm missing something but I cant seem to figure out what.
2005 SS/SC paired with a F23 from an HHR.
FD: 4.17
Tires: 225/40R18
Speed ring teeth: 29
So with the above info I should have the following numbers correct:
FD = 4.17
VSS Tire Revs Per Mile = 822.88 (rounded)
Pulses per =23863 (rounded)
With the following set in HPT, I am not getting the right response at all from both the Speedo or the software. So I initially thought it was the VSS on the trans, so I switched that puppy out and no dice, same numbers appear.
Is there anything else I could be missing here?
Note: I do not get the same RPM values for every combination. in fact this tune now gives me the lowes values. The base tune had gotten me to at least 5 RPM. Also, no other information was changed outside of these settings.
