So... I made a silly mistake that I should've noticed quite a while ago. In the same way i goofed up the CAN Low pin in the CANF connector, I had the entire DTM connector pinout mirrored (shown in photos). Once fixed it was immediately detected and started providing data! Thank you for your time, sorry to have wasted it. Is there any way to pitch in to the coffee fund? <3

I left the car in on with my can bus disconnected at the ecu CANF connector for 10 minutes, and the sensor is still cold to the touch. With the ignition on, confirmed 12.7 volts at the DTM connector again How screwed am I?

Between the DTM and JST connectors: CAN Low = 1.0 ohm; CAN High = 1.0 ohm Across High and Low at the DTM connector: 119.1 ohms Same, but at the JST connnector: 119.4 ohms JST connector with CAN Lambda plugged in: 119.2 ohms

Pretty sure I'm looking at this correctly... :/ After it sitting for a day, I now get 2.46 volts on both CAN High and CAN Low as well Still the same result in PCLink, all errors appear after clicking "Apply" in this window.

4 photos attached. My soldering isn't the prettiest, but the pins do not bridge to eachother as far as i can tell. Leftover solder on pin #2 per my previous mistake.

I am using a CAN PCB cable with the solder-style connector; wired in accordance to this diagram. Initially, I had CAN Low on pin 2 which resulted in 120 ohms across the two. I purchased 20awg wire on amazon and twisted it myself; could it be due to an improper twist or spec? The more I looked i came to that conclusion myself, and purchased 50 feet of pre-twisted wire here: https://store.ctr-electronics.com/can-bus-cable/ Thanks for the quick reply!

Hi, Thanks in advance for taking the time to read this; this is my first endeavor into standalone ecu stuff so it shouldn't be a surprise that even after weeks of research i'm still running into problems. Following the setup instructions in the installation manual, I get "device not detected" when searching on CAN 1 - CAN 2 on the R53 is used for the factory cluster and other stuffs At the Deutsch connector to the CAN Lambda module: 12 volt = 12.80v; CAN Low = 0.20v; CAN High = 1.20v; Ground is good. 12 volt is wired according to recommended diagram in installation manual Measuring across the CAN pins in the connector, i get an even 60 ohms. CAN1 Errors: Acknowledge Error, Error Passive, Bus Warning Transmit Error Counter: 136 CAN DIG #1 State = ON Attached is the base configuration file from PCLink with my attempted CAN setup per the provided instructions.
