Thanks everyone for the feedback. I really appreciate it. What load option works well with dcoe carbs, TPS or MAP? Anybody have pictures of their setup?

Isn't MAP based on vacuum?

Yeah I think you'd have to drill ports in each of the runners and plumb into an accumulator. I was interested to see if that's the approach or if I'm thinking way out of the ball park

I dropped it all together, just rev based. Map is most accurate.

Ashish. I'm running MS for both fuel and spark, so my situation is a little different, and I'm also running ITB's. My original intention was to run solely on MAP, but then move to the more advanced mode of sort of blending MAP and AlphaN (TPS.) The way I run MAP was to put a little vacuum port into each of the four throttle bodies, then run these to a common tube that supplies a MAP signal to the ECU. By ganging the four like this, apparently the signal is steadier. After running with it like this for some time, and also doing some tuning work on a dyno, I honestly just decided not to pursue the idea of blending in TPS. My understanding is that TPS provides greater granularity at high rpms and WOT, but for "normal" drivability, MAP is actually better. If yours is for the race car, then this may not be the logical approach. In the photo attached you can see the tube I made as a vacuum collector (stainless tube just to this side of the valve cover with little black hoses feeding into it.) This is before I moved to an airbox, but the basic set-up remained the same.

Those mustang AFM's are easy to interface...

 

...oh, wait a minnit...

Thanks Grover! Great looking setup.

Looks like there is a tachometer board for the megajolt as well. Guess I'll need that as well?

Hey guys

Looks like I got the bulk of the stuff on order.

Does anybody have the part number handy for that ford crank sensor?

Head to the nearest junk yard and grab one off an old Escort or something. DIYAutotune.com might sell them too.
