This one does and supports an iac stepper valve as well as pwm iac. I was looking at the ms3 evo mini. But this efisource box apparently does. Seems pretty cool.

MS3 Gold Lite with 8ft Harness – EFI Source
If I ever ditch my MS3 I might go with the MAXXECU hardware. They do everything plus support the 8 speed 8HP transmissions all in one box.

I use a trigger wheel cut from the CAD diagram Subcom sent me. It cost me under $40 to have it made. I probably have the diagram if he can’t find it. I use an unmodified magnum distributor; cap and everything! I went with a 4150 style throttle body because I wanted to retain my carb hat and existing charge pipe configuration. There is also airflow distribution to consider when converting a carburetor manifold which tilted my decision towards 4150.
I use a microsquirt which has a similar number of inputs/outputs to the unit you’re looking at, and I regret it. I’d strongly suggest choosing something with more inputs/outputs especially since you’re already interested in data logging. You may also want to look at slightly bigger injectors(120lb?) unless you’re sure to be done with e85. I’m at 85% injector duty cycle at 15psi, 12:1afr, and 50% ethanol with 96lb injectors.

Yea, I'm not using a stock pulley, so I think I can order a solid style trigger wheel and then have it cut to fit over the lip on my balancer ring. My balancer has an extra ring on the outer edge that would be perfect to center a wheel on. If you guys find the cad that would be cool, I'm not opposed to changing out my crank pulley. I can always set everything up with the msd box and prep it for a later upgrade to CNP.
As far as I/O on the ms3 gold lite, so far it looks like it will handle what I need at the moment. But it also boasts the ability of adding a can us expansion module. But I have been eyeing the normal gol
d box too.
I'm not set in stone on injectors, but 100lb/he should handle 1000+ HP on gas. E85 probably won't happen unless they build a station closer lol.
I can whip you up a DXF file to have cut if you get me dimensions. Pictured below is my crank wheel setup. I welded a .250" aluminum ring to the back side of my crank pulley, drilled and tapped for a steel trigger. The steel trigger wheel is a .125" mild steel 36-1 that I had cut.
Here's my setup for the cam sync sensor. It's off a Jeep 4.0, mid-90s I think, with an aluminum adapter.

Any specific crankshaft sensor you guys using? VR style or Hall effect? I was thinking about running a ford styled VR that way if something happens they should be easily available at a parts store.
I'm using a Holley Hall Effect sensor for my crank and a Ford Explorer Hall effect sensor for the cam. 3-wire will be hall effect and I like the square wave they produce.
I use the Cherry Hall effect sensor on crankshaft and the factory magnum distro for cam sensor.
Here’s another handy option for your trigger wheel I discovered the other day. Sendcutsend has a 36-1 trigger wheel template that can be customized.

Thats A good idea.. I did find a trigger wheel that I think will work. I just have to center it properly. I also started getting parts, found a 5.9 distributor at summit on the clearance shelf for 10 bucks, someone removed the bottom stop, which is an easy fix. Got some fuel filters and fuel line, intank fuel pump setup for my fuel cell with twin 340lph (for now). Bit by bit.
More bits. Lots of connectors and wiring showing up. Also thinking about running a blank dash insert and cutting it to fit a NexgenEFI digital dash. Will clean up all my random gauges and make it nicer.
