Hey ShakeZilla19 - I just read your build after your link in the wheel bearing thread. Just wanted to thank you for putting me on to the Glowshift oil filter thing. I have always wanted to add some gauges and that is the easiest way I have ever seen to do an oil pressure gauge.
Just a little update. I purchased an MS-2 system and got it in the mail today. Will post pics when I get a chance.
It is an open source standalone ECU. Meaning it replaces your stock ECU and runs the engine alone. Fuel, Spark, boost, idle, hell it is possible to do nearly anything with an MS. Water injection control, IMRC control, nitrous... ect. It is a low budget DIY solution to engine management.
Started building the MS-II. Completed the first big chunk, which is the power circuit of the unit. Used the stim and a DMM to test voltages at various points. Everything checked out!
Completed the Comm circuit. Getting everything setup so the MS can talk to the PC. Burning software onto the MS processor. Live data streaming from the MS processor !!! Everything up to this point checks out!
@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.
the solder joints look very good. there are a couple leads that could be trimmed a little but as long as they don't cross over and short it's all good. a friend of mine built a megasquirt board also and your solder joints look better than his!
