How does the dmax sense a cylinder misfire. I have seen lots of post on here when pistons go, just never thought of how it did it.

mostly from monitoring crankshaft speed.

Nice "M" ..... I have a 1950 M and a 1953 Super M ,1955 400 ,1957 450, see my Garage ;)

those Farmalls Need turbos!! I could plow twice as fast with mine after i turbocharged it. But i think it uses about four times the fuel! The effiency sure goues to hell in a hurry! Nice tractors though, my wife has a 450 with loader, my favorite early IH.

seems it would be hard to pinpoint which cylinder misfires in relation to rotation speed. I guess i am underestimating how presise the timing pickups are in these. either way i hope to never to have to ask anymore question related to misfires!!! thanks for replys
