Thread: TPS, MAP & RPM signals needed for stand-alone trans controller.

  1. #1

    Default TPS, MAP & RPM signals needed for stand-alone trans controller.

    Good Morning. I’m getting ready to put an 8 speed ZF behind a new Hemi. I've found a company that makes a controller for the ZF. It requires a TPS, MAP, RPM signal to function. Can those be output somehow or do I have to splice into the sensor signal and pickup RPM off a coil pack?

    HP or Dominator. I’ve bought the harnesses, but not the ECU yet.

    RPM & 0-5V signals (3-wire, Hall-Effect) can be split to two devices. Conversely, thermistor (2-wire) type sensors send a variable resistance measured in Ohms; this signal can not be shared by two devices.

    So I can pull RPM off the Tach wire in the harness, I can run a second MAP sensor or split it’s signal, TPS becomes the issue?

    No, I said RPM & 0-5V signals can be split. A TPS is a 0-5V sensor.
