Hey guys. Zero experience with the 86 platform, but have been playing around with BMW CAN bus stuff for a few years and done a bit of Motec firmware development.
Laying out plans for a full cage track build and pretty much gutting the OEM electronics. So far I think I'm just keeping the ABS and EPS, but wondering if anyone has logged CAN and determined if the TPMS data stream carries actual tire pressures. On a lot of BMWs, the iDrive display doesn't let you see actual pressures, only "ok" or "not ok", but the CAN stream actually transmits the 4 tires pressures when active, but only at 5 sec transmit rate. This may still be useful enough for data logging when overlaid with other data. Anyone have any idea? |

Hey everyone, I was wondering if anyone managed to get Can-bus data using a raspberry pi and a PiCAN shield. I am able to use the Cansniffer can0 to see the data, however, using it in a program is where I'm running into trouble. I am encountering a problem with the PIDs having a value greater than 256 (a byte), which gives me an error with the python-can module of:
self.data = bytearray(data) ValueError: byte must be in range(0, 256) I am aware this has more to do with the coding side of working with Can-bus data than what the post has mostly talked about, however, I have been stumped on it for a while and thought I'd ask here to see if anyone has done it. Thank you all for your time, if you have any questions about the code or anything please let me know. The code I am trying to get working: [URL="https://github.com/blupants/chupacarbrah"] |

I have contacted the people developing the python-can module with the same question, however, I will still post on the StackOverflow forums page to see what they say. Thank you again for the input! |

CAN Bus communication issue
I'm not doing an engine swap, and certainly I have little feel for most of teh technical discussion here, however I do have a CNBUS related issue.
I have been getting a lot of CEL light issues which the code reader says are "CANBUS Unable to Communicate", along with some pretty strange electrical demons (IE: trunk suddenly pops open while parked or driving, engine continues to run after key off and removed). I'm chasing my tail on this stuff and coudl use some expert advice. I'm trying to avoid replacing teh ECM and other modules blindly. The car is an early 2013 (2012) 6 speed, not modifications at all and hs about 87,000 miles on it. Help! |

I did some searching in here and didn’t notice it mentioned, but does the factory ecu have the terminating resistor in it? Trying to get my Emtron setup and think that might be my issue, but wanted to confirm. There is 0 info available about canbus integration with Emtron that I can find.
