OK, first off, yes I understand how electronic igntions work. Buuut... how does the computer on a 2200 pick up the position signal to know when to fire? Do you think it would be possibly to tweak this sensor so that computer thinks the crankshaft is, for example, 4º farther forward, hence advancing the timing 4º?
AFAIK there's no chip, reflash or reprogramming tool to advance timing on the 2200 so this is my ghetto idea, based on the old-fashioned days of twisting distributor caps...
Any thoughts, or am I just blowing smoke here?
well at least your thinking
but honestly i don't think it is possible, and sounds kind of dangerous, as you have no idea what "tweaking" would do what to the sensor
say you tweak it for 4 degrees advance, but in reality it does say 17*advance, i don't think that its a good idea to attempt
It's the crank position sensor that give the signal for firing (I know it is on the eco, i think it's the same thing for the 2200) Correct me if I'm wrong so I'll learn something new!!!
isnt this just advanceing timing via msd dis2? if so people do it all the time and its nothing new. or are you talking about a manuel jobbey if so take pics

you CAN'T alter the CPS signal. If you move 4° on the CPS signal, you move the WHOLE signal. There's 5 notch on the crank. Each one as a job. IF you would build something to "retard" the signal 4°, the car would have any power left.
A good example is the 87-88 2.3. They had the firing notch at 0° and the 89+ had the firing notch at +15° If you use a 15° crank in a 0° block(witch is about the same thing you want to do) it would not have any power and almost not run. Same thing if you use a 0° crank in a 15° block.
You have to modify the timming via the Ecm or between the Ecm and the ignition module.

Ah, ok. But there's no easy way to modify things at the ECM really, right?
nothing else than an MSD system. Megasquirt maybe.
Like I said before, unless yo go all out N/A , it's not worth it to have a few more degrees of timming.

if you still want to try it on your own you should take a look at the steeda kit for the 4.6 mustangs. what you described is exactly what it does. mabey you could take some ideas off of that and fab up something for yourself. advancing the cps would be the same exact thing as turning the distributer on older motors. just make sure whatever you do is adjustable and if all else fails you can reset it to stock
