E46 M3 CAN bus setup
Posted: Sun Jan 07, 2018 9:29 pm
Hoping someone that's got the track logger running on an e46 can chime in. I'm trying to get set set up on an 04 E46 M3 but seem to be failing.
I wired up an ethernet cable per instructions here: https://wiki.autosportlabs.com/BMW_E46_CAN I used positaps to hook everything up.
The unit powers up fine but doesn't seem to pull any CAN channels. I used the CAN channel setup for the car from this post by Mustangkev. viewtopic.php?t=5438 Even though that setup was on RCP, I think it would be just the same on this.
Based on this I wired CAN high from pin2 (orange) on the Ethernet cable to Yellow/Red in the e46 harness and CAN low from pin3 (green/white) on the Ethernet cable to Yellow/Brown in the harness.
I then programmed the RC with the config in the above post which seemed to take, but the dashboard shows all of the PIDs at zero.
Lastly, is there any explanation on what the LED colors mean? I get a frequent flashing green with a less frequent flashing blue when the car is running. Not sure if that is good or not and I can't find any mention of LED colors in the instruction wiki.
Appreciate any thoughts on this...
