'03 COP Settings - DIYPNP - Car Is Barely Drivable
My car runs like crap and I think it's ignition related. I have another similar thread with more detail, but it's not specific so it gets no love.
I recently swapped in a '03 motor after my '00 motor died. I transferred over the intake manifold/TB, cam angle sensor, along with the crank angle sensor and 4 tooth trigger wheel from the '00 motor.
Attached is a screenshot of my current Ignition Options, however after looking at Hustlers commuter MSQ for comparison, I noticed a few options that may explain my issues:
Spark mode (mine vs Hustlers)
4G63 vs Miata 99-00
Ignition Input Capture (mine - Hustlers)
Falling Edge vs Rising Edge
Normally, I'd just try them out but I don't want to FUBAR anything here by selecting the wrong settings when it comes to ignition.

Thanks for the confirmation Matt! Figured out I should be using the falling edge setting based on my crank trigger wheel.
Unfortunately, the can does not start. Cranks well. Getting fuel pressure. I'll have to do some logging later to see what's up and confirm sync etc.

I have a '99 and some settings are different. Most importantly I have the input capture as *Rising Edge* you have Falling Edge.
Also my trigger angle offset is 6.0* and I'm using 4.5ms Dwell.
Since mine runs rather well, I'd wager that my settings are OK. Change to Rising Edge and see what happens.

Now the car wont start at all with attached settings.

Your ignition signal:
My Ignition Signal:
Looks like something's off with your hardware. Since I'm using the MS3X, I don't know the DIYPNP at all. But maybe you have to use pull-ups, or jumper something differently, change some pot settings....

Thank you for the replies gentlemen.
It looks like I'll have to track down the NB2 crank wheel, crank sensor, and cam angle sensor. I thought the '00 sensors were transferred over, but I was obviously wrong.
I appreciate the help. At least I'm on the right track now to getting this thing running well again. Thanks again everyone.

I thought all 99+ were the same 4/2/1.
For everyone 4 teeth of the crank, there's a single tooth, then double tooth of the cam.
your pattern is 4/2, which looks very similar to a regular 90-97 signal; which probably explains why it ran in that mode on the MS.

Since the car runs like garbage with the same sensors/settings that worked well for the '00 motor, I will source the related '03 parts I am missing and wire according to Sav's VVT swap directions.

You will need the NB triggers to get VVT working. However there is no reason that your engine shouldn't run well off the NA CAS. It will be down on midrange power, but it should still idle and drive well enough. I would work on getting the engine running correctly NOW and before making further changes. It's just going to make troubleshooting more complicated if other stuff goes wrong.

I'll have to refer to a 96 base map to get an idea of the setting differences. I've changed so many settings already trying to figure this out.

Turn it back to the settings it ran with. Then figure out, why it's running shitty.
Are you running on all four cylinders?
If it's runniong crappy, my experience is that it's almost always spark related. Timing wrong, or no spark.
Tunerstudio has an option where you can turn off individual injectors, assuming you're running sequential fuel. This allows you to turn off cylinders.
Or you could go old school and just unplug spark plugs to see which cylinders are contributing.

It doesn't add up and that's why I'm so confused as to where to look next.
