i was under the impression emulators facilitate chip read/burn,
i know what you mean about frustration of having to burn chips every time, but for the price of an emulator i think its worth waiting till the point where im frustrated before shelling out the extra $$$ (nearly double the read/burn)

Unfortunately the Ostrich and Romulator will only allow you to emulate a chip and have no reading or burning capabilites. You download your code into the emulator off a pc and then the code runs from the emulator rather than a chip. With the Ostrich it has it's own battery so you can leave it connected to the eec instead of a J3 chip adapter card (eg Craig Moates' F1 or F2) and you could drive around with it in place until you are happy with your chip tune. To avoid having to buy a chip burner you can send the binary to someone who has a burner and get them to do it for you. Not being able to change the code and see the immediate effect on an engine is unthinkable to me now.

Scort that supressor is not essential to the working of the car, its ok to leave it out, some tuners even take them out because of the delay of the signal to the map sensor once its chiped.
Edited due to my 'conquering device' up sorry

BTW your OFAC, and OFAB pin outs are the wrong way round
I knew this was going to happen at some point.
Yes mate, I know your feelings as stated in the other post.
With regards to pinouts, those pinouts, are as I have measured them. Which is now coming up to a dozen looms in total.
Lets think about it logically, your saying that an XR2i, that uses the digital type map sensor, uses the same pinouts as an OFAB ecu. And not the digital type OFAC sensor. It makes no real sense. The XR2i ecu will almost definately have the same pinouts as the OFAC one.
If you check your OFAC/OFAB descriptions, you will also note that there are plenty of people questioning it. Because its wrong.
I'm not going on what I have been told here, I'm going on what I know to be 100% correct on every loom I have measured. Why would they change.
How many looms have you actually measured?
I'm not going to get into an argument about this. As I have always said, whenever these changes are made, you should measure them, and do research for yourself.
Stu at MSD also agrees with these pinouts.

Sorry for causing a bit of a dispute, i have just gone throught all my notes from 3-4 years ago now about OFAB and OFAC and they are the same as yours, when i do my conversions i follow what i have written down that will explain why they work
Looks like a made a type O on the guide and it will be corrected ASAP, sorry for the inconvienience this has caused, looks like you will be getting all the PM about this now
Take it easy mate and sorry
It usually takes someone to point out my 'conquering device' ups in public to get me to question my self and what has been written.
The Guide in FAQ has been ammended to my notes in front of me and is now correct, Scort would you like to check it out for me as i dont want this going any further than it has.

Learnt an interesting fact the other day.
When converting to E-DIS4, there is no need to change the rev counter. A standard one will do.
Using external E-DIS, run a wire from pin 11 on the E-DIS4 unit to the rev counter; problem solved as this a clean rpm output. And gives you the right number of pulses per engine revolutions, disregarding the need for EFi RPM counter.

Right then boys and girls!
Moving on to ECU's codes & compatibility!
Here is a fairly comprehensive list of EEC-IV ecu's and their codes. I have only included CVH & Zetec ecus.
What I am suggesting we do, is link all compatible ECU's. The amount of posts that are put up about which ECU is compatible etc, we can point them all here.
So, If you have done your 2.0 conversion,could you please post up which ECU you had and changed it to, and I will update the list with linking ECU codes!

The guys at Ford had fun and games making those names up didn't they? I mean, I've heard some damn funny ones, but that list is enough to make you bring your tea and biscuits back up with laughter!

Andy.B :I know some of the 1.1 CFi ones are GERM
And FLUX as well. Not exactly the flux capacitor.

Scort - superb writeup there mate, i was just posting on xrtwo.com about info on that and thought id search on here!!!!
BTW any ideas what this is? I have dropped a FRST engine into my xr2 and have put the loom in (OFAC), I just need to plumb it to the car. I think it might be a suppresor for the rev counter but not sure! Any ideas?!
Thanks
Chris

Scort is there any way round me having to get an EFi rev counter for my ERST? or can I do what you mentioned before with pin 11 off the EDIS?
I've got 88 spec clocks in mine if it makes any difference to the rev counter...
I can get hold of 90 spec ERST clocks no problem its just getting the XR3i EFi clocks is the problem, especially on this rock!

I've got 88 spec clocks in mine if it makes any difference to the rev counter...
I can get hold of 90 spec ERST clocks no problem its just getting the XR3i EFi clocks is the problem, especially on this rock!
You got it in one mate!
Using external E-DIS, run a wire from pin 11 on the E-DIS4 unit to the rev counter; problem solved as this a clean rpm output. And gives you the right number of pulses per engine revolutions, disregarding the need for EFi RPM counter.
Good luck,
Steve

No worries mate. You can use your standard clocks.
The wire from the clocks will already be in the engine bay bud. It's just a case of sorting out which one it is. It comes out from the fuse box area, and is green.

UPDATE.........
Early Zetecs came fitted with external E-DIS. I have recently fitted a 2.0 to my orion, and wanted to make use of a decent 2.0 Mondeo ECU. All Manual Mondeo's are fitted with internal E-DIS.
For this setup I used a DESK ECU, I also tried a DEWY, while I was at it. They both worked fine. It's worth noting that you will need to change the MAF to a 2.0 one also. The 1.8 one is calibrated wrong.
I will start with a bit of an ECU pinout chart, as I usually do!! There are a few pins I have not included, for instance Air-Con etc.

It's obvious from even briefly looking at the pinouts, the main problems! Injectors 1&2 are in completely different places. Also the CPS is connected directly to the ECU, rather than the E-DIS unit.
Firstly, disconnect your battery, and remove the ecu. Then try and remove the wrapping tape on the part of the loom that enters the engine bay, to the E-DIS unit.
You will need to run a new wire to the ECU from the CPS. I used a piece of 0.25mm 2-Pair screened cable. This basically needs to be run from the CPS right up to the ECU plug, and connected to - Pins 55 & 56. I had some pins from another old loom, with about 50mm of cable still left on them, as I don't have any ECU plug pins, I soldered the wires to these and inserted thepins. One of the pins is already taken up. Remove this pin and leave it out for a minute.
Once this is connected you can swap some wires over for your injectors.
The coil pack centre wire is an ignition live, and the ECU pulses each coil. I used the old wires that were connected to the injectors, cut and connected them to the DIS pack. These connect to pins 58 & 59,(to which they are already connected) they are fire cylinders 1 & 4, and 3 & 2 respectively.
The next cable and pin changes to be done are for the injectors. You will have cut the cables to use them for the coil pack. I used the two of the cables from the E-DIS unit (to which there are four), and connected them to the injectors. These then need moving from their current positions on the ECU plug, to pins 51 & 51, injectors 1 & 2 respectively.
One of the last connections to be made is for the Tacho. You will have had a green wire running from the E-DIS module. It will be the only green wire there, this needs connecting to the blue and yellow wire which comes from the E-DIS unit and goes to pin 4 on the ECU plug. Bell it out to ensure the colours are the same though!
Pin 16 on the ECU needs to be connected to current return ( the chassis ). I used a short piece of wire connected to the ecu, and connected it near the ECU. This is for the internal DIS.
You will end up with one spare cable going to the ecu, to which I put come heat shrink on both ends and taped back out of the way. You will also have an ignition live feed that went to the E-DIS unit. This also needs to be heat shrunk and taped back out of the way.
Once you have finished, wrap it ull up nicely with loom tape, and your done!
I have been running a 2.0 on 105 1.8 management for a little while now (mainly because I'm lazy!) but I only noticed a slight increase in power. It did however make the engine run much smoother.
Hope this helps someone,
Steve

Engine Coolant Temperature Sensor (ECT)
Checking
Ensure Ignition is switched OFF
Disconnect ECT sensor multiplug
Relieve residual pressure in the cooling system.
Remove ECT sensor from engine.
Immerse ECT sensor probe in coolant of specified temperature, and check resistance between terminals.
0 deg C - 8800-102000 Ohms
20 deg C - 35000-40000 Ohms
40 deg C - 15000-17000 Ohms
60 deg C - 7100-8000 Ohms
80 deg C - 3000-4500 Ohms
Crankshaft position sensor (CPS)
Ensure ignition is switched OFF.
Disconnect CPS multiplug
Check resistance between CPS sensor terminals. It should read 200-450 Ohms.
Vehicle Sensors
Vehicle speed sensor (VSS)
Checking supply voltage
Ensure ignition is switched OFF
Disconnect VSS mutliplug
Switch ignition ON
Check voltage between pin 1 and ground. It should be Battery voltage, so between 12-13v
Checking operation
Ensure ignition is switched OFF
Disconnect ECU multiplug
Connect multimeter between pins 4 & 40
Raise vehicle and turn the road wheels.
The meter should read fluctuating battery voltage.
Hope this helps,
Steve

frst ofac trouble!!!!
hi im new on here and im having a lot of trouble with my frst.... i read the post on the ecu's and when i checked my ecu its different from ur info?????
Converting an OFAC loom to OFAB
1) At the ECU, pin no. 27 (marked on the multiplug, brown wire) needs moving to pin 8, which is empty (this is the CO adjuster signal wire).
2) Pin no. 45 (brown/yellow) needs moving to pin 27 - this is for the MAP sensor.
on mine!!!! ofac ecu.. pin 8 is brown and pin 45 brown/yellow and pin 27 is not connected??? plz help!!!
the reason for doing this is cause i bought the car recently (a non runner) and the previous owner said it was the ecu, so i got one off ebay but when it arrived it was the OFAB ecu instead off the OFAC ecu. so i thought id try the ecu out before i send it back,,,,, but still no good!! any idea most appreciated... regards gasman
