Bet you lot are all sick of wiring problems but does anyone have the pinouts for the above ECU's and are they all the same (or very similar)?
I have a 2.0l silver top engine as well as the loom that came with it.
I've been burries in the haynes diagram for ages for the 2.0l petrol mondeo and it's not really making sense. For instance by the diagram for that car says, the pin 1 (og/ye) should be constant live by the diagram but the thing is, compared to the diagrams i have, on the loom ECU plug itself, the pins don't even start until pin 8 on the plug which is a ye/gn but on the diagram says pin 8 should be a vt/bk which would go to the fuel pump relay.
I don't have a problem finding the wires for another example, the outer pins on the coil pack by the diagram should be bn/bu, bn/gn which they are that's no problem finding the correct wire codes, they match BUT! the diagram says they should go to pins 58 and 59 ECU whereas on the ECU wiring plug, these 2 wires actually go to pins 26 and 52.

Maybe i'm being dumb here but the diagram just doesn't correlate with the actual loom plug
The wires are going to the right plugs/sensors etc but they don't seem to be following the same path back to the ECU plug.

Any help would be appreciated

You shouldn't really rely on the haynes as correct. Pin 1 should be 12v constant and is on most of the ford ecus and there should be more wires before 8 Fuel pump is 22.

Coilpack is 58 and 59, throttle position sensor has the same plug and one goes to 26 if thats what you're looking at.

What loom do you have?

[Chrism_frst]

Hi mate, thanks for the reply.

I'm confused too! I converted my series 2 escort to efi using fiesta turbo management and managed that no problem using the haynes.
I've took a pic of the ecu plug. I'm not sure what loom i have
I bought a 2.0l silver top engine from ebay out of a Mondeo that came complete with the wiring loom that plugs where it should etc. I didn't get an ecu with it though.



If you can make out the numbers being 1 to 13, it doesn't start till pin 8. It's got me well confused.
I might have to remove all the pins from the plug and start again when i get the ecu.

You may find it easier to source a 1.6 Fiesta Si engine loom and wire that into your car loom as then the DEEP, DESK and DEWY ECUs can be plugged straight in without having to move and change pins

Scott

[MB7201]

Yeah, get a si loom. That is a loom for a eec5 ecu rather than eec4 which is why it is completely different. The desk/deep/dewy ecus won't even fit the plug.

[4992jk1]

the reason you are having problems is that the pinout in the haynes manual are usually for the EEC-IV which has a 60 pin plug set in three rows or 20 pins each (10 each side of the bolt) but the EEC-V has a 104 pin plug set in 4 rows of 26
from the picture you have posted that looks like an EEC-V in which case your pinout will be wrong.
James
p.s. i do have pinouts for both the DESK and DEWY if you want but i dont think they will be much use.

[Chrism_frst]

Dumb ass what i am

Thanks for clearing that up for me guys. I was really just trying to save myself the hassle of sourcing other looms by converting that one i got with the engine, i don't mind getting stuck in. Looks like i'll be trawling a few local scrap yards and of course ebay for a loom and ecu. Need to get myself a 1.8 inlet too then i should be ready to start moving

[4992jk1]

if you need pinouts i have ones for BLOB DESK and DEWY if its any help

I'd appreciate them if you could James, i'm sure they will come in useful. Thanks mate.

here you go mate i hope it helps
i do have a couple of other pinouts for but they arent for zetecs and believe me because i have tried it dont use one from the wrong engine because you can get it to work but it is never reliable as i had a 1.8 zetec that we tried to run on a 1AFA which is for an RS1800 and it ran well when we could actually get it to start but once it stopped it was a real pain to get it started.
James

[Chrism_frst]

Appreciate the help mate and i'll take your advice.
Is it so essential to go for the 1.6 si loom as it might save a bit hassle if i find one of the above ecu's in a breakers yard with the matching loom and just wire that in.

Cheers.

[MB7201]

Deep/desk/dewy are all 2.0 mondeo ecus without pats and with internal edis, which is a straight fit for fiesta si loom when fitting a 2.0. Blob is the same case but this is for the 1.8 engine. You just need to wire the engine loom into your existing car loom for it to run.

What engine has the car got at the moment?

[4992jk1]

the only thing i would say about that is that according to the lists i found DEEP is a 1.8 ECU and DEWY runs external EDIS not internal. so if you use a DEWY you will need the EDIS module.
James

[MB7201]

No, it's definately a 2.0. All of the list I've seen say it is and its commanly used for the si conversions e.g. http://www.mondeo4x4.co.uk/page.php?38

Also all manual mondeo ecus run internal edis as far as I know.

[Chrism_frst]

The car is literally bare atm, i've took everything off it and started again with it. The engine that used to be in was a fiesta turbo engine but fancied something a little more reliable for track as that's the intention of the car. I've thought about jacking the whole injection idea and fitting some r1 carbs for a bit of a extra kick but i'm not so sure yet.
I'm my own worst enemy, i'm too indecisive

[4992jk1]

well if you are looking for power then fuel injection is the way to go, you get a lot more power and a smoother ride too. and im not saying that DEEP wouldn't run the 2.0l but everything i find tells me its a 1.8 http://www.elecauto.com/vol760.htm
and im sure DEWY runs external edis as i have a pinout for it and the injectors are in the wrong place for it to have internal edis.
James

[Chrism_frst]

Useful link that is mate. I didn't realise the DEEP and BLOB ECU's were for 1.8 models. If i can i'll try to source a DESK as i'd rather the 2.0l gear. Your not the first person to mention that about the injection system neither.
I couldn't find the DEWY in the list, which cars did those come from?

[sailorbob]

The DEEP ecu is from a 2.0l Mondeo, there is very little difference in programming from the DEWY ecu, see ecu-program-map-differences-updated-20-08-05-vt110061
The differences do not include the 'Engine Displacement' (aka SARCHG) parameter.

[4992jk1]

well the DEWY came from an escort but I'm not sure what year.
James

[4992jk1]

the other thing i thought of is that most zetec cam profiles are very similar so you could probably run a 1.8 with a 2.0l ECU quite well as long as you used the right MAF. or if you wanted less restriction on your intake you could run a larger MAF with a small circuit inline with it to change the signal to the correct level as this would still give the correct signals but have less air resistance.
James

[sailorbob]

The DEWY ecu is from a Mondeo too.

[MB7201]

Deep=desk=dewy more or less. All are mondeo 93on 2.0 ecus without pats and internal edis. The pins are the same except where ecus have functions included or missing. Mapping is about the same apart from I think one has slightly different timing.

The 1.8 mondeo ecus are blob and blip which are the same as above but mapped for the 1.8 engine.

[antonio31]

Hello,

I have a problem and maybe can you help me. I have an Escort mk6 with an 2.0 16v zetec silvertop engine, with DEEP code Ecu. I have an aftermarket exhaust manifold ( stainless steel ) and the egr sistem was remove from the engine, the inlet holes were filled and i connect only the sensors ( Egr solenoid and Dpfe sensor ). I made the test and i have the following error: 332 (R,M) EGR did not open/respond during test or if memory code, did not open intermittantly.
Sometimes when I press the clutch the engine dies and doesn't work fine (doesn't go round).

Has anyone know if the Desk or Dewy code Ecu's has this egr sistem? Because as i see in 4992jk1's post this ecu hasn't egr pins (or if there is another 2.0 ecu without pats, internal edis, manual transmision without the egr sistem)

Or if you know how can i hack the ecu to think that the egr sistem works fine.

Thanks a lot,

Antonio
