timing pickup for efi
ok. heres a really good question. I have a 1964 for f100 with a 292 v-8 that i am contimplating putting efi on. now, all efi units use the ignition to tell the efi where #1 is, now, I have a points dizzy right now, if i was to put in a points elimination kit that uses a optical triggering, will that trigger the efi????? also, for the most part, what kinda signal does efi systems use or reqire???? hall effect??? magnetic???? will a aftermarket dizzy trigger it?????? also, what kinda system did ford usein the tfi system????/ is that a hall effect triggering system???? or a magnetic triggering system????? I guess, I just wanna know how to go about triggering the efi so I can use efi on this less common motor.

The TFI uses a magnetic pick-up in the dizzy. Nothing special on knowing where #1 cyl is since the cap and rotor do this. Not sure how the SEFI knows which cylinder is firing though. The batch type systems used on most non-HO engines just fire 4 and 4 injectors together.
What type of system are you looking at? Most come with everything that you need if you are going aftermarket.

thats why i am asking. If i know what type the tfi is, maybe i can duplicate it some how. arethe durasparks hall effect or magnetic?????? i think they are hall effect but not sure. see, i am try'n to put TBI efi(not multiport. intake ports are stacked instead of next to each other) on a vintage motor. I know that i can convert the stock points dizzy to duraspark or with a points elimination kit but wasnt sure as to what would work. maybe i can take the pip from a tfi dizzy and make it work somehow in the stock 292 dizzy. as you can tell, tryn to do this on the cheap. msd makes a dizzy for the 292 but i ont have 400 bucks for a dizzy.

The Duraspark has a magnetic pick-up as well. Does Performance Distributors have a DUI for the Y-block? I haven't checked. I have one in my 351W that I put in my 63 and it is a nice quality unit.

On engines having sequential electronic fuel injection (SEFI), one tooth on the vane cup is smaller than the rest to identify when cylinder No. 1 is at 10 degrees BTDC. The width of the PIP signal generated by this tooth is smaller than that of the other teeth and is called signature PIP.
