hi guys ive got a 2.0ltr mk1 mondy engine in my rs1800. If anyones thinking bout a 2.0ltr conversion i have to tell you, you wont be able to run a 2.0ltr ecu on it unless you change the loom. ive bin trying to sort mine out for 4 months now and its been to loads of different people to see if the car will run on a DEEP ecu. no such luck! it would cost £400 to re-programme it because of the PATS. i now have to run the original rs1800 ecu and have got that tuned to suit the engine best it can. the tuner told me it would never run quite as good as if i had the 2.0ltr ecu in but what the hell.

as far as i know this is just for the RS1800, not the Si's.

[DeanoW]

its the same for my XR 16v (as i found out after buying a new DEEP unit ), how much would custom (omex, etc) management be?

[SimonT]

Right,

The laster fords had PATS and from what I've researched its a f**king pain.

Simply purchase a very early mondy ECU with no pats. Job Done.

Failing that its aftermarket managment time.

Omex is about 550 + fitting

I personally would go with Megasquirt. Cheap budget mangment for around 300 - 3500

[DeanoW]

300-3500 doesnt sound very cheap

[Fiestasi-Andy]

300-3500 doesnt sound very cheap

no but

Omex is about 550 + fitting

is..........

glad you got it sorted finally mate!!

[dee_RS_2ltr]

theres a racing place in birmingham that makes ECU's specially to match every little thing on your car so no matter what you put in, it'll work. that costs about £1000 though

[sailorbob]

May be a dumb question, but why can't you swap the pins around on the ecu connector to give you the loom mods you need. Unless there is something like different sensors used you should be able to do it this way.

[James-UK]

Do you know what years/engine codes/ecu codes are required for non pats ECU's? - Are the ECU's interchangable?

For example you i get a PATS engine and loom and simple plug in a non-PATS ECU and it'll work?

its not as easy as that mate and in any case i have never heard of that being done before. probably cant.

no mate, if you have an engine with PATS you need an ecu with PATS aswell. this is the problem with mine.

Surely if you get a PATS engine with non PATS ECU & loom it'll all bolt together and work though?

[disc]

Hey!
What is this "PATS engine"? As far as I know PATS mean Passive AntiThief System, so what "PATS engine" you talking about? PATS is in ECU - you need car key with chip in it (red one is needed for programming up to 10 new keys), ECU itself, reciever and loom and you are now in the game! I didn't really try this, but some Mondeo guys must have more info. Once I've read some info on a Mondeo site but... can't remember.

How do you tell if an engine has PATS?

Thanks

The engine has no PATS!!!!!
If the engine is still in car ask the owner for spare key. look at the key - if there no any parts for opening/removing so the key has no PATS module in ti. Get the original key away from car and try to start the engine with spare key. if engine start the car has no PATS. Then quikcly get ECU, engine and loom and go at home!

[DanS2i]

I brought the engine at the end of last year, the engine was from an early MK1 mondeo auto!

It was already out of the car when I brought it!

Is there any other way to tell?

Thanks

Dan

So you got just the engine or engine and ECU???

Where is the problem? I can't understand!?!?! My english is poor but I can read!

fast google search says:

"PATS is an acronym that stands for Passive Anti-Theft System (Ford also calls this SecuriLock). It is also called a transponder key. It is a security feature found on most (if not all) new Ford products, and what it does is disable your vehicle's starter unless your specially programmed key is used to start the vehicle. There is a computer chip inside of the key, and without that you will NOT be able to start the vehicle -- even if you have a regular (non-PATS) key with the correct cuts, it will not work."


SO as I sayd before you need an key (with PATS module in it, matching PATS code in ECU), reciever, loom, ECU (mathcing PATS code in key module), a Haynes manual (electirical), some luck and you are in the game!

If you have just engine and ECU there's no way to know if ECU have PATS or not until you plug it the loom. If you have ECU try to plug it into some Zetec Fiesta, Escort or Mondeo loom and start the engine. BE AWARE - if car is with internal EDIS module (in ECU) you will fry yours! Try this with eary Zetec powered car.
More questions?

Another google answer:

"ScyTek PKF
Ford Transponder Bypass is designed to temporarily bypass the Ford PATS passive anti theft systems when remote starting."

Only $21.67!

Order it from States!

Do you have a engine wiring diagram for your RS1800? If yes can you send it to me and I'll have a quick look and compare it to a DEWY ecu (similar to DEEP).

Also is it the RS ecu or Mondeo that has PATS?

[andymac]

The search facility is dead useful too...

Was going to post a link to fiestaprojects.com but the site appears offline ?!

sorry mate i dont, ive tried the TELL one aswell and that didnt work either.

im 99% sure that all the mondeo's have PATS (passive anti thief system) mine is a mk1 engine aswell bud. the ECU therefore woulod have PATS aswell but my wiring loom wasnt set up for that because PATS wasnt avaliable on the early RS1800's. i would have to get an Si wiring loom and swap it all over for it to work.

Interesting read

I'm doing a 2.0l conversion but on an 8v 2i. so i'm having to do a lot more work loom wise.

I'm using a Mk 1 mondeo engine (1996 i believe) and i've got hold of a DEWY ECU

I'm retaining the 8v car loom and i've sourced a 16v 2i Engine Loom (inc injector loom). bit of jiggery pokery required with the 2 connections but my mate is sorting that.


I've been reading up today, especially about ECU's, Looms and this EDIS thing. The 8v 2i has an external EDIS and, by looking at the 16v loom that i have, so does the 16v 2i. What concerns me now after reading this post is does the DEWY ECU have an internal or External EDIS ?

Oh, and about this PATS thing - how can the engine have it, its got to be the management (ie ECU)

Chris

very true, only the ECU has the PATS. i put it in wrong in the post above, that was from everyone else talkin bout the engine having it got confused, DUH!

[sailorbob]

Right, done a bit of research, time to deal with some of these.

RS1800 up to 01/94

External EDIS
No PATS

RS1800 after 01/94
Internal EDIS
Has PATS

(Dates are from Ford info)

PATS on the early Fords was an external unit (ie not in the ecu)

Not all Mondeos have PATS eg the DEWY ecu I've been tinkering with doesn't.

And finally for Project_XR2i_Trackcar - DEWY has internal EDIS, pin 58 connects to coil 1 and pin 59 connects to coil 2.

[dee_RS_2ltr]

so your saying that the DEWY would work on mine?

[sailorbob]

I'm not sure, but I cannot see why with a bit work it shouldn't (he said, sticking his neck out)

What year is your RS?
