Flesh Gordon Posted January 27, 2010 Share Posted January 27, 2010 I need to change engines soon as the head gasket in the 1.6 is on it's way out I'll be going for the 2L Mondeo engine Thing is I needed to get the keys and locks fixed regardlessas it is, I've only one key on the Escort and it's fairly bent and starting to wear out too , I've no other spare keys, hatch door can't be opened with the key as the cylinder was vandalisedand even to start the car the key will only enter in one way due to the curve In my case would it work out better If I kept the Internal PATS ECU from the later mk1, early mk2 Mondeo I'll be using and have the Escort run from that new key/lock set? If I do is it a job for ford only or could it be done privatley? Cost wise I know it won't be cheap either way Link to comment Share on other sites More sharing options...
Stu Posted January 28, 2010 Share Posted January 28, 2010 PATS Mondeo ECU won't work in an Escort without some serious frigging around. I spent some time looking into this so to enable a straight PATS to PATS swap, no pin changes, just reprogramming, and didn't get very far. I even had a factory reset ECU which recognises the first three keys you put in automatically and this wouldn't work either. I came to the conclusion that the Escort and Mondeo PATS systems differ (3 vs 4 wire) and left it at that. I think SteveB has looked into some PATS stuff beyond where i've gone, so might be worth asking him to look at this thread. Link to comment Share on other sites More sharing options...
SteveB Posted January 28, 2010 Share Posted January 28, 2010 You can use TAXI or TELL ECUs and keep PATS when you do the 2L conversion. You'll need the mondeo transceiver and key(s) as well. The escort wiring goes to the same pins on the ECU but all wires are brown so you'll have to trace through (as I can't remember the escort plug pin layout). From the mondeo transceiver white/green goes to pin 5 on the ECU, green/orange goes to 38, yellow/green goes to 41, and the 4th wire black/green goes to chassis ground somewhere.

Stu Posted January 28, 2010 Share Posted January 28, 2010 SteveB- do you think it's the transceiver that differs then between the Escort and Mondeo? Link to comment Share on other sites More sharing options...
SteveB Posted January 28, 2010 Share Posted January 28, 2010 SteveB- do you think it's the transceiver that differs then between the Escort and Mondeo? Internally they look very similar - different board layout but near identical component presence. The ECU though has a different chip set, so I think it is a combination of the two.

Stu Posted January 28, 2010 Share Posted January 28, 2010 I think it may have been a TAXI ECU I was doing my testing with, and if so it's still sitting there waiting to see 3 fresh keys. If you want to do some testing with it you're welcome to it. Link to comment Share on other sites More sharing options...
SteveB Posted January 28, 2010 Share Posted January 28, 2010 (edited) I think it may have been a TAXI ECU I was doing my testing with, and if so it's still sitting there waiting to see 3 fresh keys. If you want to do some testing with it you're welcome to it. I'm using TAXI myself. Because everyone goes for DEWY, DESK or DEEP for their conversion, I managed to get hold of one with transceiver and a red key for £20.

If so did it require any wiring changes other than the PATS transceiver? Link to comment Share on other sites More sharing options...

The wiring for the mondeo and escort are pretty much identical - when you compare the two the differences are just the bits that are missing. No guarantees, but just drop the ECU in and wire the transceiver - done. Link to comment Share on other sites More sharing options...

No guarantees, but just drop the ECU in and wire the transceiver - done. I think I got to pretty much the same place as you with regards to wiring investigations back when I looked at it. The missing component back then was the Mondeo transceiver. I'd spent a reasonable amount of time on it and decided it wasn't really worth any further effort. As you say, the core pins are pretty much the same throughout all the i4 ECU's, only changing for internal or external PATS (injectors etc). It might be worth someone else trying to do this conversion and if it works, document it as a better alternative to using the old '93-94 ECU's.

When you say better, is that just better because you can keep the PATS system? Link to comment Share on other sites More sharing options...

Squiz Posted June 1, 2010 Share Posted June 1, 2010 Resurecting this cos Im very curious to know if it actually worked in the end ??? Did anyone do it ? Link to comment Share on other sites More sharing options...
SteveB Posted June 1, 2010 Share Posted June 1, 2010 Resurecting this cos Im very curious to know if it actually worked in the end ??? Did anyone do it ? Well I don't know if anyone else has tried it, but we're running a 2L 136PS silvertop in a Fiesta with Mondeo PATS ECU using an Escort loom and it works just fine!

Squiz Posted June 1, 2010 Share Posted June 1, 2010 Would you PM me and elaborate ....Im undecided between 1.8 115ps or a 2.0 silvertop !!This might help me finalize the decision Link to comment Share on other sites More sharing options...
