Well, I got it running OK over the weekend and test drove a few times, letting the Autotune start to do its thing on a WB O2 sensor.

But I am still very confused about how much fuel this thing is requiring compared to the basic calcs.
For my injector flow at my fuel pressure (2x TBI injectors each ...

I bought some flow-tested and matched pair of "61" lb/hr injectors. I will be working on it this weekend. This is my plan:

- Run an injector flow test in Megatune starting with aprox 1ms pulse width and tweak to find the exact opening time of the injectors.
- Configure Megatune with the actual open ...

From what I recall the fuel pressure gauge was showing about 12.5 to 13 psi.

Thanks for the link.
I don't remember seeing any color coding on the injectors, but I will look for the part #.
Unfortunately the car is in another city and I only get to work on it about one weekend a month.
So I have to ...

Hi all. After a couple of month of gathering parts and plotting and planning everything, and then a couple of weekends of installing everything, I have completely converted over from a Holley 390cfm 4brl carb and distributor, to a 500cfm 2brl GM TBI and Ford EDIS-6 under MSII control.
The engine has ...

It turns out my board had been damaged.
After looking at the schematics for the optoin line, I followed the problem to a broken PCB trace between D1 and D2.

Bridged the trace, and now I have RPM input and O2 response... so far looks like everything is responding as it should!

Thank you for the offer to help. It would be great if it is just a software or firmware setting that I have overlooked. That would mean that my hardware is so ok. :)
This is my first attempt at all of this, so if you see anything glaringly wrong, please feel free to point it out!
.MSQ File should be ...

Update: I have confirmed that every component and jumper should be in place up to step #55, which should at least give me all inputs into MegaTune from the stim board. All of the capacitors and resistors are correct values-- the diodes and transistors are much harder to read the numbers tho to ...

Never-mind. After digging deeper, it looks whoever out this thing together simply stopped at step #55. There are about 19 required components missing (that I do not have). I just figured they were for optional configurations that were not being used.

So yeah... I have bigger problems that no RPM ...

Running firmware 2.891 on a MS2, V3 board. Testing done with MegaStim board V2.2 with 12v feeding it. The Stim board was purchased fully assembled from a supplier "confirmed works". I purchased the MS2 board from someone who had someone else build the kit for them. It is built for Ford EDIS ignition ...
