CAN anyone help (CAN bus on MS3Pro)
I know "didley-squat" about CAN, so be kind (yeah, right the said).
I recently got a MS3Pro, a rebuilt engine and a "EGT To CAN" module from ECUmaster and I'd very much like to module to communicate successfully with the MS3. The documentation for the EGT to CAN module is marginal to say the least and consist of this manual which has some minimal directions on pages 3 & 4 on the default settings of the device and some mention on how they might be modified. https://cimg3.ibsrv.net/gimg/www.mia...e991a47590.png Not knowing where to go from there, I found this article on msextra where someone was asking the same question as I had, "How do you set up this module on the MS3?" Well, then suggested some settings in the "CAN Receiving" table; https://cimg2.ibsrv.net/gimg/www.mia...b3f8298944.png After making this change, I got...nothing, zip, zero, zilch, nada. A datalog show zeros on all 4 channels. But, if I hook up my laptop to the EGT to CAN module directly, and use the ECUmaster software, I can see temperatures showing, so, the module is conditioning th thermocouples but nothing is being read by the MS3, or my setup is garbage, or both. I went to YouTube University and found So I turn to this bastion of knowledge to seek wise counsel. Can someone hook a brotha up? |
Step #1: Verify wiring
Report if that works. Step #2 is gets more technical in that you'll need to verify the actual messages being transmitted on the bus with a USB-CAN adapter. |
I checked my connections, and voila! CANH & CANL were swapped. Thank goodness because I started looking into tool to look at and/or debug CAN bus signal and my head (and wallet) were starting to hurt. I seem to now be the proud owner of an operating CAN bus EGT sensor!
Thanks! |
