This passage tells you everything you need to know:

The zig zag lines listed as 3k and 2k are resistors. The Diode is the triangle with the Bar. It only goes one way. Ground is obvious and 5v is just 5v of power. I have a circuit that uses opamps that scale the signal in a linear fashion and it uses a few pots for a little bit of adjustment. All this is null and void though since a chipped ECU is a much better solution.

Ok that's great toalan. so are you gonna post instructions on how to build the afc or is it just to show us what you're capable of building?

It is not worth your time, money and effort to build the afc. There is not real schematic, most of the work was code. For the price of materials and the pogrammer, you could pick up an Apexi. Plus the last thing I need is to provide support for an AFC. The AFC was more for interest and education rather than a full time solution, infact I am still running a FMU. There are bugs here and there, mostly has to do with noise on the input and power lines.

I am working on a full time solution that is computer programmable, it wont have the lcd, it will be very similar in principle to the greddy emanage system, i have begun development work on this already. so far the specs are 21(map input) x 21(RPM) user programmable map output points, 21(map input)x21(rpm) user programmable timing retard points, 2 extra 10x10 3d mapped outputs, 2 extra inputs which can be used as an axis for any of the outputs. Datalogging for 20 seconds, turbo timer (if I have time), Elecetronic boost control, and it will be totally firmware upgradeble. This one will be for a retail market, hoping to price it around 100 bucks without the boost soleniod and maybe 130 with the boost soleniod. It will be pretty much a full solution for your fuel and timing needs. No idea when it will be available, not selling anything right now.

If your ECu can handle it I reccommend using uberdata, heard lots of good things about it. I will give it a try myself.
