Well it started. but it wasnt running well at all.
Here are the data logs that I got while cranking and one while it ran I believe.
Couldnt get it to stay running. What should my trigger angle offset be? Is -10 wrong?
Thoughts?

So im attaching another log of when i got the car running. It will ONLY run when i set the ignition settings to single coil? Is that right? Why would it run when i set it like this? Can anyone chime in and help me out? I really want to get this thing working...
I have also included the screenshot of my ignition settings to see if you guys can tell me whats wrong. I hope this helps and i hope you guys can help me. Good news is that i got it running, but its running awful. Another thing i did was tell it to use fixed timing table at ten degree. I have attached a screenshot of that screen also.
Thanks guys!

Yes I do have the vacuum line connected to the MS from the intake manifold. I was away all weekend and didnt have time to get a log. But do you know why it would run only when i set it o single coil? Or can someone tell me if all those igntion settings are right or wrong?
Thanks
Thanks

Check the vacuum line again. If the MS is seeing 100kPa while the engine is running, then it will run very rough and bog down.
Single coil is definitely not correct, no idea why it runs well with that option set?

Without changing from single coil, can you test the all four coils using the output test mode? Get all four plug wires on the valve cover, and test for spark using Coil A and Coil B. Then switch to the settings below and test again. Check if the igniter gets hot with the settings below every 15 seconds - you don't want to blow your igniter!
This is what it is supposed to have.

Well last night I tried again and switched it back to wasted spark mode. And it just doesnt have any spark when you switch it to Wasted spark. I have no idea what is going on. Does anyone know if there is anyone in the NJ or CT area that I can meet up with and they cna see if it is something wrong with the unit or maybe something I am doing?

I've never touched a DIYAutoTune MSPNP before (or a V3.57 board to be honest), so I did exactly what DIY recommended me to do. If there wasn't a 5V pullup on the cam sensor, then I wouldn't add it. Still strange how it run on the local's car though. is everything else ok?

well, still needs a pull up...just like the v3.0 board.
but you never build it like that, you go with the second opto.
From Ben Circa '00 when I last did a v3.57 board:

There's not much to it. Treat it like a MS2 V3.0. The main differences are that it's already set up for pwm idle valve and the 5v pullups are built into the spark outputs.
Whatever your favorite tach input mod is should work. I typically will run a 12V pullup to JP1 pin 2, and set the jumpers for VR inverted. Spin R52 and R56 6 turns CCW, then spin R56 appx 2 turns clockwise. 2nd tach to JS10 with 5v pullup.

its entirely possible it didn't need that pullup, I wasn't able to sync without it...but it would have never worked when one of the spark outputs was set for fan control 
Probably why it ran in single coil mode, albeit on 2 cly.

ah, probably why it didn't sync, since I had to remove the ribbon to run the stim,
Then I'm going to conclude it was the output on d16 set to fan control. which is a spark output.
I guess I'll pull the resistor back out...just got finished packing the box up to mail back ...
