I was wondering what is the best loom to use for 2.0l zectec conversion, The loom I have in my Mk3 is no good at all, so I need to start from scratch.

I know my options are, but I not to sure on certain things? internal, external EDIS, compatable with 2.0 ECU, and ones without PATS

(1) 1.6 8v xr2i - alot of work
(2) 1.6 16v Si - comes with PATS
(3) 1.8 16v xr2i- ?
(4) 1.8 16v RS1800 - ?
(5) 2.0 16v mondeo - alot of work

So any info would be great. so I can start looking out for parts I need.

Cheers

well im running a 2.0 (DEEP) ecu on my std m reg fiesta si 16v loom and its fine. Ive also got a complete rs1800 loom here if you need one as they are the same as si ones aint they

[Cellze]

Cheers Sunil, I let you know if I need it.

I think Lou (fiestakingfisher) used the RS1800 loom and ECU for her conversion aswell, as she was in the same situation as me, starting from scratch. I should have brought an si from the start, would make it alot easier.

But I want to make sure that the RS1800 loom didn't come with any PATS I think the earlier regs (k) didn't come with PATS at all, but I not to sure

Do you think the RS1800 loom would be best to use, to get round this problem?

rs1800 loom would be fine i would have thought . But i cant be 100% on that. The one i have is from a K reg it came with me old engine. Dont run an rs1800 ecu though it aint a 1800 so dont use an 1800 ecu use a 2.0 one

[Cellze]

Looks like the best option, but just want to make sure, before I buy everything and build everything and realise it won't sart because of the PATS

Was you old engine an RS1800?

I know about ECU problem as it won't be fuelling right, plus like you said I need the early 2.0 ECU with DEEP can't remember the other codes, but I know what you mean.

What about the EDIS is it interal or external?

I don't suppose you'd be willing to part with one of the sub looms from the RS1800 loom would you

I need the sub loom with the Crank postion sensor, coil pack connector etc on

If so, name your price

All mondeo ecu's are internal edis mate. I have an 8v 2i nearing the completion of its 2.0 conversion. From my experience - don't bother with the 2.0 loom unless its an early one complete with the ecu. 1.6 si loom is internal edis so is ok to use with a mondeo 2.0 DEEP ecu. 'Project' on this site has a 1.6 si loom available.
I'm using the 1.8 16v loom and ecu and i'm going to upgrade with a 130 ps ecu or get ot chipped for the correct fueling. Either way, if your going from an 8v, its still a pain in the arse[b]

Hello


I use the XR2i (same as RS1800) Loom and ECU with superchip. And I set(hope right word )

the fuel pressure to 3,3 bar with a fuel pressure controller from motorsport

For 2.0 conversion I used only the 2.0 Head and bottom end and the 2.0 Air flow sensor(more rate of flow then the 1.. All other parts for example Inlet manifold,camshafts,water pump, oil pump , sump are from my XR2i 1.8 130 ps

Runs without problems.

Bye. Rico

Can you use an early 2.0L Mondeo ECU with an 1.8 16V Xr2i Loom?

Thanks

Dan

[German Fiesta]

Imnot sure but I think.

The same cables and sensors.I think the 2.0 ECU is in basic the same as the 1.8 but with a other program. The rest is the same I think

[Project_XR2i_Trackcar]

Can you use an early 2.0L Mondeo ECU with an 1.8 16V Xr2i Loom?

Thanks

Dan

no

all 2.0 mondeo ecus come with int edis, as i said before the 1.8 16v has externeal edis - plug it in a nd you will fry the ecu

[Cellze]

Cheers All

So these are my options: the ones highlighted are the ones I rather use.

(1) 1.6 8v xr2i - use early mondeo loom and convert the bits i need from the loom and keep ECU

(2) 1.6 16v Si - comes with PATS, any chance of removing the PATS,

(3) 1.8 16v xr2i - Is it the same as the RS1800 loom, with external EDIS

(4) 1.8 16v RS1800 - does it have external EDIS, so have to keep rs1800 ECU, Does it come with PATS

(5) 2.0 16v mondeo - use early mondeo loom with ECU - alot of work

Sorry to make a big deal out of this but I just what to make sure that I am starting on the right track without causing me problems in the future

Cheers

l have a K reg rs1800. l've put a mk1 2.0 mondeo engine in and the loom wont work with a 2.0 ECU. l've been to loads of tuning specialists to see if they could sort it out but theres no chance. l've had to go back to running the rs1800 ecu with the engine. lt runs a bit rich but apart from that its fine. Apparently you can use the Si loom, that would be the best option.

[Cellze]

Cheers dee_RS_2ltr

RS1800 looks alot more trouble then I thought, as you was saying if I use early RS1800 loom which doesn't have PATS I have to keep the ECU aswell. Which i didn't really won't to do

I think the early RS1800 had external EDIS so that might be the problem with internal 2.0 ECU, not to sure?

I was going to use the Si loom but I was wondering about the PATS if there is away of removing them from loom, and plus using this loom it solve the problem of Mondeo ECU.

Still not sure whats easier to do?

Cellze

[dee_RS_2ltr]

apparently from what ive been told, if you change the loom to the Si one then;

a) it will work with the mk1 engine
b) you shouldnt need to worry about the PATS either if you use the DEEP ecu.

[Cellze]

I think I will be using the Si loom, because I can use the internal 2.0 ECU and MAF and the Si EDIS which is internal aswell, plus the 2.0 ECU will give the correct amount of fueling and air flow for the 2.0 engine.

The only problem know is that the Si loom with PATS, can I remove them or if I buy the 2.0 ECU without PATS will this make the PATS in the loom useless, which will cancel them controlling the ECU?

Nearly there now

Cheers

Why not sust buy a solid high mileage Si as there is afew about around 100k mileage so can be picked up cheaply. Then you will have a mk3.5 shell, most of parts needed for 2.0 conversion and the si interior is the best one going in my opinion.

With your loom question I am running the 1.6si loom in mine with the 2.0 (DEEP) ECU no problems.

I know it sounds easier, but the amount of work and time that has gone into the bodywork its to much to just to change over, plus I ve got the Recaro interior already which is alot better in my opinion
I could have done a turbo conversion would have been alot easier but I want something a bit different and more reliable.

I think everyone recommends the DEEP 2.0 ECU so i defiantly be using this, but also I heard people saying that the DESK and DEWY ECU runs alot better?

Cheers for the advice

Ok, so you cant run a rs1800 loom with a 2 litre ecu.
What if you are fitting a throttle boddie kit with omex manegment from burton. Going to fit a 2.1 litre engine in my rs 1800, but I see the kit is the same for the 1.8 and 2 litre zetec engine. can I keep my original loom and ecu and let the Omex system do all the work ect, it works on both engines with their original loom and ecu???
would save me alot of work and brain pain
