If you put carbs on a fuel injected, dispack engine, how do you go about sorting a spark?

The engine can't be converted to run a dizzy, so needs to utilise the dispack setup, but I can't work out how you get the ignition timing right

If anyone has a clue, or a hunch, go.....

X16

I knew about Megajolt, but it got a bit confusing saying it needed basically a FULL ford ignition setup and ecu for it to work

I thought it would be as easy as - crank sensor, trigger wheel, coil, dispack, megajolt, but it seems that you need loads of other stuff too :S

It needs ford EDIS parts because the megajolt ecu can't control DISpak ignition coils directly.
It fires them through the EDIS module.

Quite easy to find in a scrapyard tho..

The rest is straightfoward.

MegaSquirt can control DIS directly, but it is more expensive as its able to control fuel too.

I see, so it works like a piggyback system on the Ford EDIS setup?

It just confused me because it seemed to need the EEC-IV bit as well, which As far as I know, is a proper ECU

I suppose that's fairly simple anyway, not gonna struggle to find the bits.

Thanks.

planning to use r6 carbs?

as far as i can understand,

to run the 3d map (much better)
you will need a TPS sensor on the carbs or use the vauxhall MAP senor, to give the ECU a load input so it can work out advance better

the EDIS, well read this
http://www.dainst.com/info/edis/edis.html
basicaly doesnt need a cam sensor like most cars

so your gonna get a x16xe corsa on carbs, should be good

you dont need the eec-iv bit, thats what the megajolt replaces so it becomes mappable.
the only headaches are fitting a 36-1 trigger wheel, and a TPS to the carbs (a MAP sensor would be a nightmare do to no inlet plenum to tap into, meaning you'd have to tap off all 4 inlet runners and then fit a mini plenum to balance it out)

Just fit a TPS to the carb spindle.

Map sensor is too hard to do on a multi carb/tb setup.

A set of bike TBs is roughly same price as carbs.
And i dont really think theres any reason to choose carbs over tb's....
