hi ive just done a 2.0 zetec conversion into my mk3 escort ,ive used a zetec 1.6i k reg loom,ive got it all up and running but when i put the 2.0 ecu on it wont run ive got 2 ecus desk and dewy and both wont fire it up any ideas what to do ? if not il just run it with the 1.6 ecu but i think it might be down on power with it on

 

pats??

 

the loom i used i took out myself of a k reg escort 1.6i that didnt have pats and both the 2.0 ecus are from non pats cars,so dont understand it

 

How far do you get with the 2.0 ECU - does the fuel pump run? Does the engine control relay energise?

Are you 100% sure that the pin-out of the 1.6 & 2.0 ECUs are the same, as there can sometimes be minor (but important) differences between them?

 

Is the ECU from a Mondeo with automatic gearbox?? Mondeo MK1 with automatic gearboxes have external EDIS. Some older Escort MK5 have external EDIS,up to around 1992.

 

both ecus are from 2.0 si models 136 ps,the pump runs but the injectors dont squirt any fuel out,the loom im using has edis external i think?? its on the wiring with a like ignition module plugged in saying edis4,it seems to run ok with the 1.6 ecu i just dont understand it

 

OK.You cant use the Mondeo ECU`s.They are not meant for external EDIS. Best to do is to get a ECU from a Escort MK5 XR3i 130 PS,early models,they have external EDIS.Or try a ECU from a Mondeo MK1 with auto gearbox.

I found out this because i have 2 Escort MK5,a 1992 1.8 Zetec and a 1994 1.8 Zetec. I`ve put a Mondeo MK1 2.0 ECU in the 94 and it works,but when i fitted the same 2.0 ECU in the 92 it wouldnt start.I got a hold of a ECU from a 92 Escort 1.8 XR3i 130 PS and that worked. Later i discovered that the 92 Escort has external EDIS and tried a ECU from a Mondeo MK1 2.0 auto gearbox wich also have external EDIS,and the car started. I havent driven it yet so i dont know if it has got more power.

 

Yes, I think omgu_74 is correct.

Would this be any help: http://www.rsbible.co.uk/orion/orion.htm

 

thats great,cheers for all your replys il get another ecu sorted

 

hello everybody, I really do need help since i dont know what to do, I have a 1997 mondeo 1.6 silvertop manual transmission non pats, Ive done a conversion to 2.0 zetec silvertop, but here in egypt we do not have mk1 mondeos so i can't get DESK or DEWY ecu's :s, I am now running the 1.6 ecu :s which most people said is very dangerous for the engine in addition to power loss, what can I do? shal i just run it on the 1.6 ecu? is there a way to bypass the pats system? is there a way to diy remap the current ecu? can i make my car have pats? ie: can i use a pats enabled ECU by any way? what is the solution to this huge problem :S ???? plzzzz i need advice

 

hi guys i bought a fiesta mk3 with 2.0 silver top out of mk1 mondeo and have just started stripping it and jst wanna find out wheather i am running a 2.0 ecu the code is 93bb-12a650-ef and it has deep writtern on it and i have a black box with pats control unit writtern on it

 

Yes.

DEEP (93BB) ECU is a 2.0L Non-Pats, Manual Transmission ECU from an early Mk1 Mondeo.

Why you would have a Pats Control Unit there though... - I dont know.
