Rogue Posted May 13, 2020 Report Share Posted May 13, 2020 Is there any way to implement starter control over CANbus? I'm intending to use one of the buttons on the CAN Keypad for engine Start/Stop and the starter solenoid is controlled by a CAN based PDM.

remski2 Posted May 13, 2020 Report Share Posted May 13, 2020 I have a Motec PDM starting the engine. All the logic is configured in the PDM. Since I have auto-start configured, all the ECU is providing is RPM via can back to the PDM. (so it will stop cranking once a 400 rpm is reached) Same button is used for STOP and ECU is configured to accept Anti-theft CAN message to cut spark and fuel.

nachollamg Posted March 17, 2021 Report Share Posted March 17, 2021 Hello! I've a question, could I do same yoU did with your motec but using AIM PDM 08? Quote Link to comment Share on other sites More sharing options...
remski2 Posted March 18, 2021 Report Share Posted March 18, 2021 I would assume it can but .. It speaks CAN.. but I dont have first hand experience with AIM Pdms. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 18, 2021 Report Share Posted March 18, 2021 Yes you could do all logic in the AIM pdm, or if you want the ecu to do the logic then the workaround in G4+ is to bridge an aux out to a DI like pic below. Your starter button signal can then come in via CAN, it triggers the aux which triggers the DI and then the starter solenoid request can be sent back to PDM via CAN.

nachollamg Posted March 19, 2021 Report Share Posted March 19, 2021 Thank you both. Adam, you are like an open book!! But, G4+ and G4X have both same Can Bus protocol? I can see AIM has in their manual protocol for G4+ but a technical support man said me he cannot guarantee G4X works as well as G4+. Do you know it?

Adamw Posted March 19, 2021 Report Share Posted March 19, 2021 The G4X has the same AIM can stream yes. Some of the scaling and enumerations has changed if you are doing any custom CAN stuff. Quote Link to comment Share on other sites More sharing options...
