@pextor:
The stim. I was using an old 20 y/o iron with a jagged tip

; nicked the solder mask in a few spots. Could I use nail polish to cover them?
Here is the MS(got a new iron). I have not cleaned the flux yet. This is also about halfway through the build.
As for everything else.
This was after finishing the sensor input circuit. Basically the signals from the engine sensors. The MS can now read sensors. All of the stim pots work and the data is displayed on the PC gauges.
and.........
BAM !!!!
5 hours later about 99% complete. Still need to clean up the board and add a few mods. I am thinking about adding in an ethanol sensor and a MAF too. The ethanol sensor would basically allow me to add any ratio of gas-to-ethanol without re-tuning or even having to know the exact ratio. The MAF just because I like the versatility of MAF sensors. Although... the MS already has a MAP sensor for boost so the MAF probably wont happen.
MS is based on GM engines and sensors. Since, I plan on using it on a Ford there are a few modifications needed. Specifically Ford's IAC and EDIS. Ford uses PWM IAC valves which need a large amount of current. Enough current to blow the transistors that a GM setup would use. So, I have to add in a larger "transistor" which doesn't come with the MS. IAC's are totally optional though. So, in the meantime I can play around with the MS and try to build a rudimentary tune.
As for the EDIS, the MS sees the EDIS module as a dizzy, which makes things cake. Problem is
the EDIS is integrated into the ECC-V..... So, ill need to either trick the ECC-V, in the 3rd gen, to run just the coil and allow MS to do all calculations. OR snag an EDIS module from an older Ford.
Thoughts?
Other little bits.
LED's on the side of the MS. Injector pulse, cold enrichment, and TPS snap indicator(flashes when the TPS changes very fast)
Injector LEDs firing(top row, center pair). Tach signal firing(next to the purple wire). Which confirms the sensor output circuit is working.
Live data from the MS.
Time to crash. :cigar:
