  • Nissan TB45 Cal file and wiring help. GTR PNP SM4

    Hi all i have an Autronic SM4 in a PNP setup for an R33 GTR.

    I have just had an upgraded chip installed to the latest version 1.12. I would like to know what settings i would need to change to suit a tb45 nissan motor. The sensor is in the distributor. It runs a single coil to dizzy setup to lead on plug.

    The TB45 has a disc in the distributor with 360 notches and internal ring has 6 notches with one having a larger space than the 5 others.

    The plug on the ecu matches my factory ecu however roughly 3 or 4 pins are different when cross referenced with a wiring diagram.The plugs are identical physically.

    I have made a cross reference chart for the pins between SM4 and R33 GTR pinouts. I confirmed it all by belling out the pins between the SM4 base board and the pins on the plug. I have not been able to find a link between any of the ignition outputs from the ecu though. Ignition O/P 1 - 4 do not bell on any pins. Could i essentially solder new wires from the SM4 board to pins on the plug? (i'm competent using a soldering iron).

    I wont be plugging it in directly as i am running an auto and it still needs to see some info from the factory ecu. I will be making a good patch loom between the ecu's, using deutsch connectors.

    If anyone has had experience with these pnp ecu's or could shed some light on the situation i would be greatly appreciative.
