This block will set up the type of shifter position sensor on different transmissions. Some will be blanked out by the firmware and other will leave the installer choices on his method of wiring. Note that the TCU is mostly concern in reverse so that it will prevent shifting gears as the shift solenoids as this action will put some transmissions in neutral or lock mode which can be detrimental.
Pot Input
The software will indicate all the shifter positions if the TCU has a signal representing all the different positions. This selection is for shifters with a potentiometer to indicate the lever position like the Spitronics Shifter or some Ford shifter models. Spitronics also manufacture a resistor encoder board for shifters with complex logic selector switches. The advantage is that the TCU only requires one input for multiple switches. This values for the shifter must be calibrated If this button is not available it is either Pre Ver 3.2 firmware or the TCU is currently on a Map greater than 1. In the last case click on 1 Map do the calibration and then click on 4 Map Switch before you save the data to TCU. The older versions were preprogrammed and could not be changed. Note than most transmissions require the shifter sensor to prevent solenoid operations in certain shifter positions and for the transmission to operate correctly. Also to activate Squad functions to eliminate transmission shock when lever move to R or D positions.
Reverse Low
This setting is used where a switch is mounted on the shifter which gives a ground signal when reverse is selected. Note that the software will only indicate drive or reverse.
Reverse High
This setting is used where the signal is connected to the reverse light between the switch and the bulb. It is a positive signal that switch on the reverse lights. The bulbs need to be working as they act as pull down resistors. Note that the software will only indicate drive or reverse.
Click on this button to enter calibration mode.
If your shifter or transmission has only 3 positions, 3 & 4 will be hidden.
Put the Shifter in Park. As a test you can go through all the positions to position up to 1st in sequence to see if the real time value change significantly. Note that the value must change for each position of the shifter. Some shifters have the same value in park and neutral then only park will be indicated on the software.
Put the Shifter in Park and click on P. It will become green. Go through the other positions R, N, D, 2 & 1. Put the Shifter in Park again and click Save & Close. Then click the save to TCU button to make the calibration permanent.
