To Shift Gears using RPM, use the Settings /Gear Shift tab and program the Launch Delay to a value slightly LESS than where the gear shift would initiate. This will keep the Grid gear counter locked into 1st gear in the event you loose traction and peddled the car. It will NOT recognize the RPM drop as an actual shift. The RPM Drop is the amount of rpm drop at ANY given time while in that gear for the Grid to move the counter to the next gear. In the Settings/ Shift Light tabs program the shift rpm for each gear listed. Every time the ignition is turned on it?ll output a ground signal on the Yellow wire for 3 seconds. To disable this function change the Power-ON Test to OFF. This RPM Shift output comes out of the Yellow wire as a (-) ground signal.
The Output Switch is a ?DELAY TIMER? that has a window switch or hysteresis RPM feature. I suggest using the Output Switch to shift with when wanting to shift using a Time Delay ONLY, and if the Shift Light function is available. If the Shift Light is being used for another function, the RPM Switch feature of the Output Switch can be used, but should be programmed together with the Time Switch to limit multiple RPM activations when not desired.

The problem I have is that 1st to 2nd and 2nd to 3rd shift light work just fine but 3rd to 4th shift does not come on. The rpm drop and the timer have remained the same . Anybody else have this issue?
