Either fit the 1.8 130ps ECU or the 2.0 ECU, both have the timings needed for the cams. Though it can be run on the stock ECU, just won't get the max power out of it. The fueling though the ECU compensates via the use of the MAF. It is the last part we need to research, though I found more info on it tonight to have a good look through. Was even thinking whether its possible to run the separate ECU piggyback to the stock ECU to make it more simple with the immobiliser etc.
If worse comes to the worse, you can just stick the cams in on the stock ECU, it will be perfectly safe, just won't reach maximum power from the cams.

If you want to do this sort of thing save the money and get a faster car or use the money for an old nippy car such as a 205 and mess about with the engine.
I fancy learning how to do engine work on a spare car in the next few year but i don't fancy looking like a ***** (no driveway) and working on my main car.

Why's that? Running lean perhaps?
And I don't see how an ECU designed for a 2.0L engine will also correctly fuel a 1.8L engine in the same state of tune. Bit pointless spending time and money if you end up with half a job. The ideal OEM ECU would be one from the 130bhp Escort, except the PATS imobiliser is not compatible.

do they have the same fuel pump? I suppose the hike in power is so minimal that the fuel pump doesn't even need to be worried about.
the only way you'll get decent power out that motor is getting it turbocharged or supercharged but the cost of that is probably twice what the car's worth and you'll get little/none of the money back when you sell it

As Ford ECU's can alter the amount of fuel going in, just not the timing. So it would run the correct mixture, just not spot on times.
And yes the best is to use a 130ps ECU, but as you said the PATS isn't compatible, thats why I was thinking whether it is possible to piggyback it.
One large reason we are doing this is to learn from it, part of the fun really, getting the satisfaction of working out a solution.
