Problem is the car is firing on only 2 cylinders.
I'm testing an ms3 + ms3x, wired in to a factory 88-pin DME connector for an m42. I'm using the ms3x logic ign outputs (A-D) through 120 ohm resistors to trigger 4x bip373's, output through the factory 88-pin DME connector to the coils. I didn't have access to a timing light when I tested the ms3 on my buddies car, as the test vehicle is a little hard to come by. I have to arrange for one of my friends to bring his car by from a good distance away.
I confirmed that the BIPs were wired correctly, and tested the BIPs with an LED tester while on a stim. I used an ohmmeter and tested the harness to the coils and made sure my diagrams were correct and I wired the adapter correctly. Injection is done via 3.57 mainboard outputs, to the adapter. I've triple checked the connections, everything seems to be where it should be, physically.
I was also wondering if anyone has any information on the tooth #1 angle for the m42. I haven't manually counted the teeth or anything, but I'm certain it is a 60-2 wheel, and online sources say 118 degrees for tooth 1 angle. Angle might be slightly off, but should not affect the operation to this extent. Composite logger shows clean and solid Crank signal, and cam signal is clean, but only comes in when the engine is above 1100rpm. Car rev's smoothly (however smoothly a 4 banger can rev on 2 cylinders) and there is no real sync loss during operation.
m42 coil packs are sequential coils, confirmed with diagrams and Matt at DIY.
Apologies in advance for the clusterfuck of ideas and thoughts, I've been pulling my hair out over this box.
MSQ and datalogs are attached with the last bit of settings I was dicking around with if anyone wants to look it over.
Picture of the setup I put together..
