could a cosworth ecu be used on a v8?
and if it couldnt control 8 injectors could it still run 4 larger injectors on a v8?

Ryan

any of the ecu L1,L6,L8 and P8 can run 8 Injectors with the correct boards.

cant see the problem in using it on a V8. Probably already been done.

The F40 runs 2 P8 ECU's

big_wig_074

sweeeeet. have seen the twin ecu thing done before on a 200sx with 8 injectors,was a cool way around the problem!
so whats required to run 8 cylinders?

Ryan

just though of an issue.

dont think the ECU is capable of anything more than firing 2 coils,

Im sure some of the tech ECU guys on here will be able to shed some light.

but i presume u will need a minimum of 4 coils to be fired?

Unless u can run 2 ECU's like the F40's

big_wig_074

4 coils?errr....i honestly dont know,but i wouldnt think so on a basic 2 valve per cylinder 5 litre ford v8.ill see what they run now.

Ryan

sorry my mistake, can just run a standard dizzy with cap

so shouldnt be an issue, its only when running a coilpack or rather multiple packs

Ryan

or do they run 2 dizzys ?

dear lord its too late to be thinking about this

i would think away from the webber stuff,,, as of cause you would need the ecu's to get mapped,, and your not talking cheap money then!

once you buy 2 ecu's, a tidy custom loom for them both, remap them both,,,,,,dont bother

buy a aftermarket unit

i might have an f40 wiring diagram here if you wanna see it

big_wig_074

this is merely educational at the moment by the way! the engines seem to run a single coil,but the dizzy cap would OBVIOUSLY have 8 leads to the plugs coming out.
go on gareth,put up the pic,baffle me!lol!
im just thinking out loud as the price of cossie ecus is rather...erm....cheap at the mo!

big_wig_074

oh and gareth,im asking about 1 single cossie ecu running 8 cylinders

I'm 99% sure my 302 will be running this

you would be asking to much of one ecu really,,,

big_wig_074

what you putting it in?what power you looking at etc?

Gareth,yeah i thought as much,but thought i should ask first!

It will be going into an Escort Cosworth and mated to a MT75 keeping the 4 wheel drive system. Transmission strength means that I will not be going much over 320bhp as I'm on a tight budget.

Why use a Cos Ecu?

Ford v8 Ecu are cheap and readilly available.

They run on eec 1V same as Cos?

There is a multimillion dollar industry in the states providing off the shelf chips to any spec far cheaper than the cost of mapping in the U.K

Almost every configuration of engine build has already been mapped.

If you need more power it's easier and cheaper to bolt on power, you don't have to go to the edge of reliability.

The V8 Ecu looks identical to the Cos and even uses the same 60 pin connector.

The standard Mustang Ecu will cope with 350bhp without any alteration.

Am I missing something, did you just want to make it hard and expensive work?

There are at least 2 add ons that allow you to modify the mapping at home.

big_wig_074

no you didnt miss anything.ive been looking at currently carb fed motors and have seen l6s and l8s for a small amount of money and was merely wondering if it would work,and 350bhp isnt enough!
this was merely to ask a question out of curiosity.

foreigneRS

just because an engine has 8 cylinders, doesn't mean it needs 8 injectors

phil_focus

true, it depends on where the injectors are being put

big_wig_074

true hence the very first bit i wrote right at the top was can it run 4 bigger injectors.im more worried about wether it would be able to receive input from 8 cylinders as obviously it needs to do something with spark etc....

There is only one company that I know of that can map the dual ECU set us as fitted to the F40 and that is MSD. There is probably more tuners out there.

Not worth it I'd have thought.
