On the ecu side In the CAN stream you setup the razor pdm at ID 500 sit it knows what to send receive etc… In the PDM software in the CAN setup you select CAN function with the same ID you used in the ecu(500). This is how the ecu and PDM talk to each other. Hopefully this makes sense I’m trying to dumb it down as simple as possible. Quote Link to comment Share on other sites More sharing options...

Thanks for your reply, I did the setup of the pdm and the ecu of the ID500. I have set can2 and the ecu can find out the pdm as well. I put the engine fan control in can Aux2 and set to 20degree to switch on the fan but nothing happen. So do I still miss any setting on it? I still have few question about do I need to turn the PDM termination to on or keep it off also I will put the heltech ic7 display later. Do I need to set the stream frame from the ecu? Thanks for advance Quote Link to comment Share on other sites More sharing options...
eric0122 Posted December 6, 2023 Author Report Share Posted December 6, 2023 Hi, here is my files. would you mind to have a look see anything wrong please? thanks alot. GC8 fury..pclx Eric.2nd.pdmc Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 6, 2023 Report Share Posted December 6, 2023 Your settings look correct. The engine fan doesn't run when the engine is not running. If you update the ecu to the latest firmware you will have a "CAN Aux 2 Test" setting in the fan settings just like a real aux pin. Quote Link to comment Share on other sites More sharing options...
eric0122 Posted December 7, 2023 Author Report Share Posted December 7, 2023 Thanks Adamw, but the fuel pump still not running when I crank the engine, I will try to update and see how's going. One more question. Do you know the G5 software can use with g4x ecu? Quote Link to comment Share on other sites More sharing options...
eric0122 Posted December 7, 2023 Author Report Share Posted December 7, 2023 I watch on YouTube and they use this PDM>voltage. Then the PDM interrupt when I store into PDM. So why happen like this? And what is this function use with? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 7, 2023 Report Share Posted December 7, 2023 You need to update your firmware, your ECU is on 6.22, this doesnt even have PDM functionality, which was added in FW 6.23. The current is 6.24. Yes you should be using G5 Pclink. The condition "PDM Battery voltage > 1" will just mean the output is enabled anytime the PDM is powered up. You can use the manual control to achieve the same. Quote Link to comment Share on other sites More sharing options...
