MS2 on subaru jdm my99 triggering problems

Post by jasaircraft »

hi
Ms2 with the latest firmware, i cant sync on this 99 sti engine, wires are ok, crank positive to pin24 and cam positive to my spare1and js10 input, both signal grounds on pin8.
the ecu sees teeth on the tooth logger but wont sync.
help please.
im using a haltech ra10 for signal conditioning which i used in the past (with this very same ecu) on a 2002 wrx and it could see rpm just fine i also tried several configurations on its dipswitches with no success.
im attaching my msq and cranking tooth log.

thanks

Just tried flipping polarity on both sensors and also using 2.2kohm across both with no success.

Not super familiar with setting up a cam sensor but is that just used for sequential?

Unfortunatelly you cant use the subaru 6/7 crank only signal you have to use both but for some reason it wont sync although it does see teeth as recorded on the tooth logger.
I just tried setting up a 36-2 universal wheel and set that on the software and it syncs fine so my problem is either in the cam signal or how it is in relation to the crank signal.

Turns out my signal conditioner cam circuitry is bad.
