Here's the Braineack method:

How to make your trigger wheel work on MS3+MS3X with sequential injection and ignition

Part 1: Making your trigger wheel work
  1. Use factory sensors.

Another day of failure.

I cut another tooth off the trigger wheel so it's a 12-1 wheel. I set timing to TDC and there was a tooth about a 1/4 inch (5 degrees) past the the crank sensor so I cut that one off. As I understand it, that made tooth #1 the next to reach the crank sensor, 25 degrees BTDC (360/12 = 30 degrees per tooth).

I cranked the motor over and got the exact same result as last time. Tach reads, then drops, syncs then drops. Then I started thinking I'd gotten the angle backwards. I'm thinking the 25 degrees was After TDC so I tried 335 degrees (360-25) as the trigger angle, which did the exact same thing. Still getting the same error code for the Loss of Sync, 2. Missing tooth at wrong time.

Add the "Sync Loss Reason" gauge in TunerStudio dashboard.

  1. Use factory sensors.
  2. Enjoy your shitty resolution 4 tooth CAS and shitty 1.6 motor because you are lazy.

Watching this closely. I'd like a crank trigger setup on my '97.

BS. There's no proof that the stock sensors/wheels are any worse than 32-1 wheel setup.

I'll agree that the 90-97 setup isn't as good since the cam signal is on a belt, but there's no reason to switch up a 99+ setup if you don't absolutely have to because the damper you are using is fixed with a really shitty wheel setup.

Yes but it is not used for ignition.

Take a timing light and see how much your actual timing wanders if you rev the engine? I can tell you that in my experience, the timing got a lot more stable after I switched to a trigger wheel.

I feel like I need to cut another tooth off the crank wheel but I hate to aimlessly chop up a $125 crank wheel hoping I get lucky enough to hit something that works.[/QUOTE]

Did any of the 36-1 threads help? The crank wheel is only 15-20 bucks. Either way, it looks like you need a CAS off the front. I got mine running with Soviet's help, major props for his knowledge.

For OBDII misfire detection only. MS does not even use it.
