What are the thoughts on ms3pro? Looks like a great package..

I'm running MS-extra with ignition and I love it. Before my rebuild I had a very small glitch @ 5000 rpm but I havent tried it once I reassembled.
I tried the VR counter circuit but I didnt have any luck. I bit the bullet and went with clewett eng

Just wanted to update, further reading suggests that rv conditioning board does not do what I need it to do. The car is up and running now with the dme and klr thanks to my forsight to put the ma inside an old dme And keeping everything hot swappable. The plan now is to go with the ford EDIS system and bolt a 36-1 trigger wheel and matching sensor to my crank pulley. Can the crank pulley be removed and attached without disturbing the timing belt? If so that will be a very simple solution that I know will work well. As far as that guy on pelican who got his car going, it was a long time ago and he wasn't Able to tell me anything about how he managed it. The .msq he had posted is a broken link at this point so I'm back to square one for now.

Sorry for the double post I'm on an iphone. I wouldn't be opposed to running the ms just controlling fuel for the time being, but the dme would still need the afm in place to generate the load signal so it can calculate spark advance. I need to have the car running speed density and for the time being it isn't running well on the dme because my car is set up to vent to atmosphere. Is there a simple way around this that doesn't involve recirculating, since that would require new hard pipes?

Rob, I've done lots of reading up on it on the megasquirt forums and it seems like lots of guys have issues with it. It works really well with some ignition systems and not so well with others. I have a spare early crank pulley laying around which will w

Will work fine because the only accessory I run is the alternator which I've converted to 5 rib already. I also located a 36-1 wheel that is the perfect size to fit the crank pulley, plus it has a mounting bolt spread that is the same as the 4 holes in the early crank pulley. I've got some steel to fab a bracket and I'm going to reuse the factory speed sensor so this is cheaper, easier, and will work better than the translator board. Will also give me a very easy and cheap path to distributorless waste spark ignition in the future.

I am updating this thread again for the history books, for my own good, and for anybody else who might want to search this years down the road. A good friend of mine managed to obtain a 36-1 trigger wheel and matching sensor for me today for the princely sum of 6 dollars. It came from a 91-96 US spec Ford escort with the 1.9 liter engine. It is press fit onto the crank pulley and it has not been removed yet. The trigger wheel is 144mm OD, just 2.5mm larger than the stock 944 pulley. It's solid except for a small 28mm hole in the center. I will be drilling four 1" holes that will allow me to thread in the four 10mm bolts that hold the pulley onto the oil pump drive gear/crank snout after the reluctor wheel is welded on. I'll be making a bracket to bolt to the stud on the block that used to hold the power steering tensioner. It will hold the sensor up at 90 degrees perpendicular to the floor so that when the motor is set to TDC and the crank pulley bolted back on, the missing tooth will point straight down and align with the sensor to give me 0 fixed ignition advance.
In the attached pic, the Escort pulley is on the bottom, 944 w/oil pump drive on top.
