Interesting......MAF igniting ether is something I didn't consider. I guess I've been lucky. I had to resort to starting fluid to get my M50 running in 15F weather this weather. Had a serious flooding problem from not letting engine warm up on previous start.
Ether autoignites at 320F. Internet search says hot film MAF operates 170F above air temp and hot wire operates 212 above ambient, but I can't tell whose sensor this refers to. Hot wire sensors have a burn off cycle that likely exceeds 320F when engine is shut off. Do you believe our sensors operate higher then 320F?
