I need speedo scaler inputs for a gear change and use TunerPro.. I was wondering if someone with Tunercat could use the speedo tool to get me the inputs..

4L60e
28" MT Radial 740 revs per mile
4.30 gears

Thanks in advance!

You guys are awesome! Where do I find the "Speedo correction factor"? I'm not see it in TunerPro.
