im stumped right now and too tired to think. normally at about 3000rpms the speedo would say roughly 80mph. 2nd time i rev'd out 3rd gear it came to 4th gear seemed pretty close to normal 102mph but still seems to be a couple hundred rpms off. I just looked over my logs a little bit and the log shows, in 3rd gear, 6612rpms i would be doing about 85-88mph somewhere along there bc i cant tell exact on the speedo. Ok i changed the trans and heres what i came up with. ill try that later tonight and see what happens well normally 3rd gear would top out around 87mph.now im hitting 80mph and thats top of 3rd gear.i didnt change the trans so thats probably why it did that. Well i just flashed the pcm with the new tires on and PPM new numbers. To convert from the 40 ppr at the VSS to a ppm value, you take 5280 ft/mi divided by the circumference of the tire (in feet) to get rev/mile, then you have.

PPM is used in the measurement of a small level of pollutants such as air, water, body fluids, etc. One ppm is approximately equal to 0.0001percentage. Which leads me into this question.I have HP Tuners and if i go to speedo opion it brings up 'VSS Pulses Per Mile' 24212 and also has 'VSS Trans Revs Per Mile' if wild weasels calculations are saying im 7.6% off and im doing 55.4mph when speedo says im doing 60mph.what if i decreased the numbers i just mentioned by 7.6% would that bring it back to corrected mph reading on the speedo?Ģ4212 - 1840= 22372<-corrected VSS Pulses Per Mile?Ģ747.7535 x. It is a part of a whole number in units of 1/1000000. when your speedo read 60mph, you are actully going 55.4 'Speeedometer reading with non-stock tire is 7.6% too fast. I went to wild weasel's how to page and came up with this: Ok so i have hp tuners and i just bought new set of tires for my car.
