Tracknite Shift works with most engines and ECUs that output a tach signal (0 to 5V or 0 to 12V) or it can be wired to the negative, switched side of the ignition coil.
Some engine management systems [I'm looking at you AEM Performance Electronics] produce a tacho signal which is only low-side switched. In these situations an external resistor should be connected from the ECU tach ouput signal to +12V. Resistors in the range 1000 to 4000 ohms are generally suitable for this purpose.
A range of cylinder options can be configured via the menus. We think we've got you covered in the following table, but if you have an unusual scenario, please contact support for a solution.
