MoTeC Global Forum

Hello,

New to the forum and MoTec, wondering if someone can help. I have an M84 and two PDM15s in a racecar. Everything is wired and 95% working. I would like to use M84 CAN data for the ECT and EOT to turn on cooling fans in one PDM. Is this possible to do with packets sent to the PDM as in input? Also would need data structures on the temperatures to set my ON/OFF temps.

Any help would be appreciated. Thank you!

Start with setting the PDM address (280 decimal, 0x118 as used in the PDM) in the M84 ECU Manager using Adjust->General Setup->Communications->CAN Setup.

Here is a thread with specific details about the fixed M84 data sent to the PDM:

For more background, you should probably take a look at this Webinar and see how the general process of setting up the PDM to work with CAN inputs works:

Awesome, thank you David! I'll get started on those things and update later with how it turns out.

Thank you again for your help David Ferguson. I got everything set up and working with the M84 and both PDMs using CAN. Was actually a lot simpler than I thought it would be. I thought I would have to construct the packets themselves, fortunately MoTec has done that already. I just had to direct the to and from and where to get what.
