weird crank signal from 36-2 trigger
 

cant get my car to start on my link g4x looking at this crank signal it doesn't look right
its a 2003 vvt motor wired into a 95 chassis, cam signal is obviously fine so idk whats up with the crank
the settings are the pre made miata nb 36-2 trigger option

Can you post your tune? All I use is the MX5 36-2 trigger settings. Don't have my laptop here or I'd look at my own scope

I took a look at your tune, and everything is the same as mine. Again, I don't have my laptop in front of me, but if I had to guess you either have trigger 1/2 reversed, or somethings up with your wiring. Has this trigger wheel/wiring worked on a different setup recently, or is it all new for the Link?

I actually forgot the sensor ground that usually sits on the engine in my wiring, now the crank definetly has definition of teeth on cam and crank, maybe my lash is incorrect on the sensor cause right now its a 0.020" and ive heard its supposed to be around 0.040". Ill upload a photo of what the graph looks like currently when I go home on lunch today. The ecu has always been indicating the cam trigger is working properly so i hope this is it.

I tried re gaping the sensor and it really didn't do anything, I'm going to take apart my wiring and shield it too because I run that cable alongside the injector harness

Is the blue supposed to be CAM? If so, that does not look like a miata cam trigger.

Are you using the 2003 crank sensor or the 95 crank sensor? You need the 2003 (BP) crank sensor for a 36-2.

blue is supposed to be cam, I got my wiring a bit wrong so I'm currently fixing it, and no cas 01-05 sensors all around.

The flyin miata 36-2 install instructions have a lot of good info, including plots showing the NB triggers.

Edit, the link isn't working for me

Ill follow these when I get home, I did re correct the wiring for my signal sources so Idk if that couldve messed up any sensors by shorting them or something, now the signa

l looks like this

Here's my values. Until you have a signal like mine, my guess is your wiring is at fault. The trigger scope is really sensitive and picks up absolutely everything, if you want a more clear trigger signal, look at the DI scope, that's the second image I attached, and you can see the more typical 1-2-1-2-1-etc of the cam, and the 30-gap-30-gap-etc of the crank.
