MPD I think the task of finding some additional PIDS would be a welcomed distraction.. I’ll go see if I can locate those PIDs for you.
CAP Help if you can I feel like maybe I’ve gone way off the rails…
I’m still struggling with coming up with an equation that makes sense for the EGT sensor. Part of my difficulty is that I really don’t know what this sensor is.. It reads 200ohm at 0c Some of the tables I’ve found for 100ohm platinum RTDs seem to line up pretty closely when I double the resistance column. I took another sensor and froze it, then stuck it in the oven for a while to get some resistance values off from it at different temps. trying to identify it. The voltage values coming out of the ECU seem likely to be the voltage drop across the sensor which from there I should be able to get resistance and then run that through an equation to get temperature. TBH the equations involved in this are making me scratch my head.. I’m no mathematician that’s for sure.
