Nice one!
If and when you do switch to MS I've probably still got my RS1800 maps available, although saying that I can't remember if we only put the MS on the 2000 engine. I'm using the original MS board. (Jim correct me if I'm wrong) Either way the map should be pretty close. The only thing to watch out for is most of the base maps available for zetecs use a 2 squirt per cycle injection method (or was it 4?). This is best for emissions, but does not allow quite enough resolution on idle if you use larger injectors. Switching it to a 1 squirt per cycle (or was it 2?), fixes that but you have to mess about with the maps a little bit. If you are planning any upgrades later, I'd switch it as early as possible. Watch your intake air temps when the weather is warm, I found I was pulling in 50 or 60 degrees air with the air filter where you have it, and on a very hot day it would not be happy when on the motorway (hot tarmac and hot air sitting just above it) plus all the hot air from the radiator. I added a couple of bonnet vents and later switched to an enclosed K&N appolo with a cold feed just above the side light. I also switched to a Turbo engine at the same time which adds lots of heat, but I'm sure the overall temps are significantly reduced. One annoying thing I found with the RS1800 ECU was that it tries to keep the revs a bit higher when there is any speed detected- I was doing my advanced driver training at the time, and you are meant to break and reduce the speed in gear, and only change gear when the braking was done. If you were in 5th and trying to break down to say 20-30mph, the engine would fight and try to keep the revs around 1500 rpm minimum I recall. Disconnecting the speed sensor fixed that and did not seem to have any detrimental effects elsewhere. The original rev counter I found over read by about 500rpm, which explained why I found it hard to get it to idle well as I was tuning it to tick over at 650rpm! I should have realised reading the MS gauges. I can't remember if we did it with the Ford ECU but with the MS we bent out the throttle stop by a tiny amount before I figured out the code to control the idle speed control vale, that may also help you with the Ford ECU. I know it's perhaps too late now, but one interesting thing, was when I swapped from RS1800 to 2000 zetec, overall fuel consumption improved. Like wise when switching to MS. Hope you get lots of nice days to enjoy it.

I am happy to say my 2+2 is now equipped with a RS1800 engine. The plan was to fit my Megasquirt ecu, but due to lack of time for new MOT, I decided to fit an XR2i ecu for now. It is a very basic ecu, but does the trick. It makes it posible to attach the Mega at any time straight onto the existing loom. As you can see in the pics, I didn't have to modify the subframe too much, just the upper bar for camcover clearance. By replacing the multi-V pulley to old fashion V pulley, with a crackshaft pulley from a PSA engine, and cvh cranckshaftwheel, there is enough space to clear the frame. Also the alternator on bespoke brackets with mini spanner is a new zetec version, but fitted with a cvh wheel. All in all is it a combination of (XR2i) cvh and zetec parts, so when you're going this route : store everything, until the project is finished! Still some minor issues to clear, but went to work with no problems, altough idleing when cold is not perfect yet.
