EVO 8 Cam Sensor

Post by NBytevenom »

I've been killing cam sensors left and right with what I'm assuming is something heat related, in my 2000 Miata.
I came across this thread on Miataturbo

Related sensor: http://www.ebay.com/itm/Cam-Shaft-Position-Synchronizer-Sensor-for-Eclipse-Stratus-/310535659584?epid=572374261&hash=item484d5e2040:g:zSkAAOSwOwZZhXm9&vxp=mtr
It seems that by changing from falling edge to rising edge (or vice versa), in a NB1 miata, one can get a more reliable, cleaner signal to the ECU for cam timing.

I am however a bit confused by what resolution one would lose by using this sensor. Apparently one cannot run VVT with this because the third tooth on the camshaft is no longer seen. Would I need to change my timing algorithm to 36-2?

Rising vs falling is certainly important. One edge is precision, the other has allot of jitter and is less precise.
