Anyone know a good resource to find certain canbus ECU ID and data. I did some searching and came up empty. From searching I found CAN DBC File might be helpfull in decoding but cant find one lol. I'm fiddling with a gauge project and made some fun progress, but finding messages on the canbus is retarded hard.

Im using a Arduino Nano, MCP2515 canbus board and a Adafruit stepper motor driver. Ive got a pretty functional ECT gauge, but still tweaking the sketch
I haven't found a working sketch for OBD2 pids might make it a little easier...

Looking for:
Oil PSI
A/C PSI

found:
ECT
RPM
Reverse
Pedal Position

thanks,
