Id like to say its just the high outputs but nothing ive seen makes me think its only those that are playing up. The car has another major issue so time isnt as tight as it was last week. i think a more knowledgeable head on the problem will be the next stage.

Okay… progress. Sort of. Now because i have 2 pdms i might be doubling the drama, but fhats where i am now. I am seeing outputs drop on 1 pdm when the other sees a change in load. Fan switching on the front causes. The rear to fail, although I dont see any events in the logging. A gear pump started on the second pdm causes an auxiliary that is powering the e throttle to fail. It doesnt appear to be just current causing this dropout as i can manual switch the outputs without affecting the rest of the system. Inducing a manual pwm output seems to cause the most disruption. help?

Dropped the tx on one pdm and the led disco of death is gone. 1 problem down. I noticed that the software/pdms are not happy to be setup together, they cross-polinate settings at random including layouts Secondly, the pdm will not connect if the ecu is also attached. Full course of restarting the app and pdm usually sorts this out. Third thing is that a fan start seems to reset/disconnect the pdm, im going through the logs and trying to source the reason thanks

I have had a go at this based on what I’ve learned using other PDMs and OEM can streams, but is it not possible to drive 2 PDMs with one keypad? Specifically the blink 12 button keypad I’d like to drive separate PDM outputs. Do I need to capture the button activity with the ecu and then send it onto the second PDM? Any help would be appreciated

That would be great, I'm just saying that's not what I observed during testing. I don't have anything on the output, so that might be why it didn't behave the way it's supposed to. I'm going to do more testing. :EDIT: OK, you are correct. If I send status to the PDM I can get it to turn on and off with just the one message. However, If I want to control a PWM output(which I cannot send with G4+) I need to send frequency and duty. This would impact anyone who wanted to send FP control or wastegate duty to the PDM, It would be helpful if this information was available.

Thanks for that, might've saved a few hours scratching my head. On my bench testing it seems that I needed to include the frequency and duty to be sent to the pdm to get a functioning input, but your LCS doesn"t have it, am I adding unnecessary complexity to this or is it a firmware/bug issue? A copy of the full LCS would make this trial and error approach redundant.

OK, I've had a few days to go over this in person with the hardware on the bench.. Is there a LCS file for the PDM comms? I can make it work, it would save time to load a file and go. Can I use CAN DI or AVI inputs from the PDM for sensors/switches? I can get the ECU to "see" a CAN DI but how do I get it to become useful. There are NO CAN DI or CAN AVI assignable like the G4X Thanks

Ok. Its just the easy stuff i need. Fuel pump, starter, and fan. Over 2 pdms if that makes it more interesting cheers

Hi guys/gals I need a little information about the CAN data streams that come embedded in the G4x series but not G4+ I am adding a Razor and Keypad to a G4+ Thunder but the CAN data streams are not available in the G4+ software Also, I will need to configure pumps, fans and such to be driven over CAN to the PDM Am I able to do this? Is g4+ limited to simple dash streams and not able to command CAN I/O? Thanks in advance
