Looks like a fun project with all those components and mc's. How is the reading material supplied by MS? I would think that someone without any electronic knowledge would find this project a challenge.

For buying, I went through www.glens-garage.com

It sounds like a good service because they test them. I have no soldering skills myself so if I give MS a shot I will have it built.
Brian-
What is your planned setup? Fuel only? Ignition with EDIS? 60-2? Stock sensors?

I chose to wait for the PIC board, since I just replaced the speed/reference sensors, and I figured might was well make it look stock and all that Plus I didnt want to fiddle around mounting the trigger wheel and EDIS sensor

Brian, whats the PIC board going to cost? Keep all that ordering info, or post it up here. I'd like to run that as well, if its cheaper than mounting an extra trigger wheel.

Brian, could you post the info or a link for that PIC controller? Do you know how accurate it is?
If I can run it off of stock sensors I will probably put one of these together this winter.

Is it that KSP guy from Latvia on the msefi forums? I was under the impression there was still a good deal at development left on that project. But you have said you're capable of coding stuff, right? I'm a mech-e, I can't do spark-e math beyond V=IR. (can't or don't want to...)
If you're taking on the task of getting the PIC to work with your car, let me know any way I can help, especially if it means we can build up/test 2 at a time and I get the second!

If its the guy I'm thinking it is, this is his description and contact info:
Well, we've already done it. The development was with the Audi original 135 teeth flywheel decoding in mind, but now it can decode missing teeth wheels as well. Other major function is coil-on-plug support. That's a small add-on board based on PIC uC. We have about 10 cars running on it, almost all turbos - some Audi S2, Audi S4, three Audi 80Q rallycars with 20VT implants, and even an Audi RS2 (yes, that beast runs on MS, too !!!). Missing teeth decoding is used on an Opel 60-2 wheel and on one weird boat engine. Our installs for the S-cars went this way - Motronic has been plugged out, in goes one short adapter cable to connect the car harness to the MS connector, and a new IAT sensor is installed. DONE. Start tuning.
Some features:
* 3 input signal (RPM, Zero, Cam) decoding
* 2 input signal (RPM, Zero) decoding for wasted spark
* 2 input signal (MT-wheel, Cam) decoding
* 1 input signal (MT-wheel) decoding for wasted spark
* Error correction and indication
* Configurable trigger output to Megasquirt - the best feature is that one could run the wheel decoder with practically any MS firmware - MS v3.0, MSS, MS2, Extra etc.
* Coil-on-plug with maximum of 6 cylinders (it could be more, but there is too small time for the dwell, and the PIC is lacking output pins). It simply takes the signal from MS and distributes to the right cylinder.
Now, the main point. I could release the code and almost all of the design to the public, but I really have no time to support it. Instead, I have time to explain the design and code, and answer questions to the volunteer from the MS comunity. The code is not very difficult, considering that PIC is built on RISC architecture - it has only 35 commands. I'd like to think that I have well commented the code. HW design is very simple. I'm sure that everyone who is coding for MS, will be able to support it. Btw, the Microchip's MPLAB development suite has a very nice simulator and signal generator for the PIC, you can simulate the code entirely on the PC. That speeds the learning and developing very very much.
But, as I said, I will not release the code, if no one is going to take the burden of support. Maybe, you, Eric? Since you are an Audi fanatic (in the N-america, wow) and a brilliant coder, it makes you a good candidate But I'm open to everyone else, as well.
ksp
p.s. If Al and/or Bruce are interested, I could send the code to them nevertheless.

As evidence of my spark-e dumbtitude, I had to google "PIC uC" to see what the heck they were talking about. This site:
http://kahuna.sdsu.edu/~tucker/pic/
...has a very detailed and easy to understand description. I learn something every day.

I got mine from RS autosport. GREAT GUY - Rodney is his name.
I used the relay board design for the 928, and have everything ready to wire up in the car when the engine goes in.

My coding skills are fairly limited but I should be able to manage the PIC... I hope
