CVH with Ford ECU

[BassMan]

I have a bog standard 1600 CVH SEiW with Webber twin 40 DCOE running on a Ford ECU (I guess the standard one). Engine was brand new from Westfield when kit was purchased (1994). ECU has the following markings on it:

Ford 91AB-12A297-GA

P #A104

2M16

CONQE

3 symbols - triangle, heart, circle.

Last time I had the car rolling road tuned the chap said if I tell him the exact model of ECU he can probably download a new map and remap it for me giving more power.

Questions:

1) can you remap a standard Ford ECU like this?

2) how much should I expect to pay?

3) how much extra horses would I get?

Thought it might be a cheap way of getting a little bit more power (currently got 101bhp at flywheel) while I save up for my Ferriday Engineering head work and new cam  

Cheers

It's not standrad Ford ECU. A standard Ford ECU won't run Webers without remapping, and you can't remap a Ford EECIV ECU...

Any chance of a picture?

[scruffythefirst]

and you can't remap a Ford EECIV ECU...

You sure?

Bass man,

Keep an eye out for older ECU's that people are selling as they swap from Carbs to Fule injection. THese may well give you all you need and be cheaper than purchasing new

you can't remap a Ford EECIV ECU

you can plug in a superchip to the diagnostic socket which does alter the mapping

and ford could remap the EECIV ECU years ago via the FDS2000 system with an upgrade, not what you mean i know but if they could do it then maybee others can now ?

The guy at Northampton Motorsport said they had recently received the software/ hardware to remap my Ford OFAB ECU but, wasn't up to speed with it, so was unwilling to do mine.

But quite a lot tolearn. I started off reprogramming GM ECUs. Really cheap and very powerful, but a LOT of work to sort out.

Motorsport developments in blackpool can do it.

Here's a pic of the ECU:

Looks as though it can be remapped then, I'll see what my local rolling road guy has to say. I'm in Kent otherwise a trip to Motorsport Developments in Blackpool would be easiest  

Thx for advice.

thats just an ignition module (edis) i think

it just controls the ignition side of things

don't know if anything can be done with these  

[cng1]

Oh I know what that is.  There's a vacuum connector on it isn't there although there's no obvious hose in the picture.

What you have there is the precursor to the ESC2 ignition modules which were used to control ignition on carbed engines.  Later these were replaced by EDIS modules which were controlled from the ECU which did the injection as well.

If it is one of those then it dates from the late 80s and is best off binned and replaced with a megajolt as it's completely and utterly untweekable.

ESC2 ignition modules

that's what i was thinking of  

ESC 2 = electronic spark control 2

[Blatman]

Which confirms at least part of what I said in my opening post...

It's not standrad Ford ECU.

So, whilst I may be a bit behibnd on the potential mapping possibilities with the EECIV, my suspicion that the item in question wasn't actually an ECU was spot on

[BassMan]

OK, so now I feel stupid

So you're saying that I have no ECU controlled system at all, just an old ignition module that can't be tweaked at all. And best advice would be to ditch it and replace with a programmable system of some sort? Am I understanding things now?

All parts came from Westfield as a total kit in 1994, including engine and Webbers so I'm surprised the factory supplied this unit if it's quite old. Who knows why!

Another rung on the Westfield learning curve .....

Sierra diffs aren't made anymore either, but they're broadly suitable and cost effective so Westfield use them.
