Seems you found something very close to my test...

4. EGR CTS to enable 36h would die when revved up.
5. EGR CTS to enable 35h would run fine when revved up.
Mark if you were to change you view in HexEdit to decimal it should show the counts, which the ADX converts to *C.
That's what I started to do when I found this issue. Then found so many different conversions I had no idea what was going on? Half of which need no conversion! Some I have found to look sane and react exactly to hex, converted to decimal. Other's are way off and must go through the A/D counts and need the conversion.

EGR was another whole issue that started the temps conversion issue.
