On the existing Ford system i guess you have the external EDIS module
driving the coil pack ?, this has a correct rev counter output on an
unused
pin, i forget which pin now but you can find the pinout on the net.
Once you have the MS it has a dedicated rev counter output.

Very informative, Matthew.
It is quite an engine: this used to propell McCarthy's Ginetta G20 in
the 2007 one make raceseries and is virtually new.
It raced three races at the end of the season and won all three,
before this engine option was banned for the next season.
The engine used to have bespoke rwd parts, but they had to go in order
to fit the Quantum, of course. All in all, it took me nearly a year to
get all th eright parts and to change parts and find the right
waterpump pulley.
I recognise certain aspects of the situations you mention: the Ford
ECU does tend to rise the revs when rolling for example.
The ECU I am using now is probably not the correct one for this engine
in Ford terms (XR2i, 8V), but understanding the MS, you know what's
happening inside. It does "self learn" in certain situations, but
only when the engine is at operating temperature and with the O2
sensor as a reference.
So, how does it do that at cold idling speed? Today I did the
recalibration at working temperature of the idlingspeed, setting the
base speed (@700rpm) and determined the normal idlingspeed (@900rpm)
following Haynes instructions.
See if the engine doesn't stall anymore when reversing.
The revcounter needs to be adjusted , still, with two diodes, because
of the two coils instead of one. It is on my "to do" list.
Because the escort rad is somewhat deeper than the cvh one, the
nosecone didn't fit! That's not amusing at 11pm, the day before MOT.
So, I ditched the electric fan in fafour of some freshly made brackets
to take the rad further in the car and asked the missus to help me fit
the nosecone. When everything fitted, we took a well deserved drink!
Mot with no problems at all! Even got a discount! So the electric fan
is also on my "to do" list. Yours is on the front of the rad, I see.
(old pics in Jims site, before turbo-era)
So intake temperatures could be rather high, with the filter next to
the battery, behind the rad. Not sure I can fit a cool-air hose from
underneath to the filter. Will see to that.
On your car, there's no battery in the subframe, the filtercasing
taking up all the space. In that "corner" it is easier to make a cold
air intake. Here, the intake tube crosses the rad-top-hose..
Driving is such a new experience! Your motto: "more power, more fun"
defenately sticks with me!
Thanks again for the input, would be pleased with maps.
Cheers,
Rolf

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.

Another zetec conversion has been done!
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.
