Racepak for stick cars

You can create additional channels in your RacePak. Create a new channel for 1st gear, 2nd gear and 3rd gear. In each new channel you can apply a formula. For 1st gear divide the driveshaft rpm by the first gear ratio. This will give you the same graph line for first gear as if you had an input sensor. You can do the same for 2nd and 3rd, just divide by their corresponding ratios. Yes you will have to look at four different lines, instead of one "clutch" graph line, but you will get the same results. You don't need to do this for 4th gear since it is 1 to 1.
