Is anyone running a stock pinto efi as I need a photo of the position against the block and also a piccy with the cap removed, all at number 1 firing please?

There is a small mark on the edge of the distributor that the small mark on the rotor arm points to when the engine is at #1 tdc. This gets everything in line for static timing. IIRC, the vac unit should point roughly forwards, and the rotor arm slightly forward and out to the right.
edit - the easiest way to set these up if it's wrong is to get the cam and crank to tdc, then pull the timing belt off and move the aux pulley round until the distributor marks line up. Then put the belt back on, and set the timing up with a strobe. It's the devil's own job to line up by removing and refitting the distributor because of the bevelled drive.

You're correct it SHOULD work like that ,but it's not as that shows up as too far advanced when you crank it.? No vac capsule as uses efi and tfi set up but the tfi connection sits at 3 o clock when it does start and the rotor arm sits past that at 4.0 clock (with cap removed obviously  ) . This puts it halfway between two leads not pointing directly at number 1 . This means effectively it is firing 'backwards to get number 1 lead ? I'm presuming that this is also misleading the ECU as to which is number for injector pulses? It's the early EECiv without KAM set up as well. |

EFi dizzys don't have a vac unit or a notch for the rotor to line up to for some reason ? no idea why all it says in the manual is they have to be retimed sonicly? obv thats booolox they time up fine as normal ?
I usually have the plug pointing at 2 oclock (veiwed from the front of the car looking down at the dizzy) then just pick whatever is nearest to the rotor when the engine is at TDC, thats roughly where they are from the factory but if you want it factiry number 1 position it's pointing at the plug the wiring loom plugs into (again 2 oclock), then time it at 8 deg BTDC with a light

must learn to type faster ;D

That's where I had it Rob , rotor pointing at plug which alos has + o - so make sense but it doesn't like it ? That leaves the window on the Hall effect totally open at trigger end , which I though was the wrong way round ie low tension circuit still switched on ? I've a spare distributor stuck on my desk here  |

in that case, my EFi pinto has a non-efi (but still leccy) distributor fitted to it.....

I've got a couple of the Hall effects WITH vac can, plus ESC2 (?) that is standalone but works with vacuum direct to seperate control unit ( but not ECU) . However my ECU dizzy does have a notch in the side but bears no relationship to anything !
Mind you , how do your injectors trigger as I thought it was by dizzy feed?

ECU takes a pulse from the distributor module (the one with "motorcraft" and the ally heat sink..)

in that case, my EFi pinto has a non-efi (but still leccy) distributor fitted to it..... Has vac advance on it ? or the notch ? does it have a lead on it or just a socket sticking out the body ? i have one here under the desk and that doesn'y have eitther, could be a year thing they changed  I've sold my setup but you could ask cortinastu on BSC he has it now and it's set to run tight unless he'd stripped it down ? whats the timing light saying it's on? did you change the octain leads that screw to earth near the coil at all ? they set the base timing for differant octain fuels? I spose the leads are right 1342 anti clockwise ? (sorry if that sound like a pee take just going through things in me head) the 2 multiplugs at the rear of the plenham can cause problems with injectors not firing if the pins are corroded, a wiggle usually diagnoses that problem. |

It could be non-standard (or just early) - it was in a B reg sierra estate, timing side is as per carb sierra (notch, vacuum, lead not plug), efi has a separate ecu that only connects to sensors and actuators (and one wire for rpm) so it's EECIII.
Can't check the timing - it's currently at the back of the shed.

Can't check the timing - it's currently at the back of the shed. sounds like a carb dizzy with a lead? EFi use a male plug on the dizzy body and a femail on the loom, the early EFi (earlyest i've had though is a D reg granny) had a large grey dizzy cap and has the modual on the side of the dizzy body so being even earlyer i have no idea not had one that early no idea why there would be a vac on an EFi dizzy they are (usually) soild and the ecu changes the timing? carb on the left EFi on the right, i have both here at the mo ( i really must tidy the front room up) ;D  sorry the timing question was to Ace  i forgot the head the paragraph to him |

yeah, it's the one on the left... Like I said though, the ecu is very simple and only does the fuelling (air temp, water temp, mass air and throttle position, fires 4 injectors in banks of 2, no lambda or ignition control) so ignition mapping on this engine is purely mechanical.
What I can't say for certain is if it left Ford like that.

What I can't say for certain is if it left Ford like that. Allways handy to know these things i talk a lot of peeps through the pinto EFi conversion so i like to know all the variations One thing though you sure the ECU doesn't controll the timming? i fitted an EFI dizzy to a carbed race engine and we couldn't get it to run anything other than a base timming setting (no advance at all) untill we wired in the ECU a and a TPS, all the manuals state the EECIV controls the spark ? here even shows a spark timming table so why have a vac advance? www.veryuseful.com/mustang/tech/engine/EECIVInnerWorkings/Not doubting you just like to get to the bottom of it, the pinto EFi has been a pet project of mine fpr a few years i played with a borrowed a tweecer for a while and that alters spark timing ? Actuslly i've hijacked this thread sorry about that  |

No worries, the more I can find out the better as well, seems surprisngly little info out there .Well, I've retimed today itturned out it was previously firing as the shutter left the slot as opposed to entering it. It also appears that either end will generate a pulse ?
Sounds stronger now but still can't check until I sort the residual valves on brakes . Had to completely redo CO setting , base idle and timing to stop it surging . Here's hoping it's right this time.
Anyone had this with the Bosch Hall effect dizzy ie firing at both ends of shutter ?

Rob, the ECU that came with this engine doesn't affect the timing at all, it's simpler than EECIV. But, like I said, it could be someone's homebrew job.

Ah sorry chap, sick, wronge end ect still sounds uinteresting if you ever get into it i'd like to see it in a pic or sumink (sad anorac coat on)  |
