Are you running 305/45R17? Question 4u
Finally getting mine mounted this weekend and wanted to know what you changed in hp tuners for the speedometer. Could you post a screen shot or what setting you changed. Is it only the the setting that says Dist? What number? 726?
Thanks

I have used the 304/45-17 Mickey Thompson ET Street R and it's pretty tall. With my stock-tune SS, A8 trans, it was able to go 116mph in 4th gear at 6500rpm. That is a 1.69 4th gear ratio and a 2.77 diff, and the math looks like somewhere around 718 revs/mile. BTW that was inflated to 17 psi on the dragstrip. As far as changing tire size for the speedometer, in HP Tuners it's in Speedo>Calibration>Sensor Calibration. Sceenshot of a stock ZL1 tune file below, and the red arrow is pointing to the spot that calibrates the speedometer for the tire.
The VSS is for the speedometer, and my guess is that the Driven and Undriven tire circumferences are used by the Stabilitrack/ABS systems. |

That is the one i thought it was, but wasn't sure. My speedo page looks a little bit different though.
Thanks for the help!

His tune file may be ECM only, while yours has TCM, too. Those three extra parameters you see come from the TCM.
