Developer Post

The irsdk_waterTempWarning is probably not something you want to use, I have it set to >110 C, but each car sets its own threshold somewhere between 110 C and 130 C. It is good enough if you don't want to be accurate.

I'm going to go ahead and add in a irsdk_oilTempWarning = 0x040 value, that will trigger at 125 C, with all current cars triggering somewhere between 125 C and 140 C.

There is not currently a clean way for me to pull the actual lamp bit, or the temperature limit. But I will put this on the back burner and try to think up a better way to get the data.
