I alctully have a bit of cranking trigger errors on one of the older impreza´s i made ,that is even with the 36-1 wheel i made,but that is also rather small ,around 80mm in diameter,and the gab is just a missing tooth,so i was thinking if that would benefit froma raised gab also??

The design that produced the scope trace is in reply #20, basically the missing tooth gap is 1/2 the height of all the other gaps.

Or have a massive tooth rather than a gap.
Next time a 36-1 or have 3 teeth and use a cam sync ;)
Good work on publishing the results there.

Now I'm actually quite curious as to what the giant "tooth" would do. I updated the drawings to have the gap at 1/2 their previous depth and a missing gap instead of a missing teeth. Going to make this tomorrow and scope it.
I guess I should note that the last scope trace was made @~147rpm. The lathe would only go to ~3000rpm, otherwise it would be interesting to see what happens at high rpms. Regardless, I will re-scope with the max rpm and compare it to the new trigger wheel that I'm going to make.

Giant tooth will not work. I have experience. missing gap 1/3...1/2 deep from normal gives best result.

Cool, good thing I checked the forums before hitting the shop. Updated my drawing:
