Why would you run an OFAB ECU on a MK1 FRS?

What inputs does it need from the engine when wiring it up, where can I get information on this or wiring digrams?

Ofab as in Fiesta turbo management? or am I completely off the ball.

rog

iTrader: (2)

Yes, I know of a Mk1 Focus Rs that's allegedly running OFAB, I know nothing about it OFAB seems strange that it'd be running that kind of ECU.

rsturbonutter

maybe its a ofam which is after market plug n play replacement for ofab/ofac which is fully mapable

Rab

OFAB on a focus? Surely not? How would all the anti theft stuff work?

vroooom ptssssh

It can't be Ofab...surely not anyway. Must be that ofam that rsturbonutter speaks of

Lol would be VERY surprised if someone had gone to the trouble of swapping over to that...the standard management is fully mappable as it is so can't think of any benefits of swapping to an older ecu, and as above can't see everything working in conjunction with it?!
I can't remember what the name of the management is on the focus but maybe it's a similar name and they are getting it confused with frst management?

Yes I am confused also, I spoke to the owner about it and it seems this is correct but need to do a bit more digging, I thought the standard Focus RS management was more than adequate. It's not in a focus now, but the engine and box are, so none of the anti theft stuff is there anymore.

That's why then. They've just used a fiesta turbo ecu and loom. Cheap way of doing it

rog

iTrader: (2)

Really? So it's ok to use that then? I thought if u were doing a conversion and swapping it all over it would make sensie to change everything and not run an older ECU.

Ofab can run it with no issues atall along as its maped properly. I was running Ofab on my old mk2 fiesta when i first put the zetec turbo in with a area6 chip kit then upgraded to pectel t2

rsturbonutter

Have just done a little research and the rs focus uses EEC-V management which is a updated verson of the EEC-IV that the fiesta rs uses. I can't see any benefit in using it over the standard management. At the end of the day why did ford create a new management if the old dated version is better. Simple answer is they wouldn't have

rog

Ok thanks, just struck me as odd since it's an older system on a new car, doesn't seem to make sense. Glad I asked though! Thanks guys!

rstdave

iTrader: (3)

Ahh kind of makes more sense if it's not in a frs....if someone had swapped the management in a frs they'd have been mad as it would be a backwards step for nothing obviously
It is only a zetec turbo to be fair so i'm guessing the ofab must be much easier/simpler to wire up than the standard frs management which might explain things a little

rog

Brilliant, really makes a lot more sense now, just need to figure out how to make the rev counter work.

Zetec_mk4_XR3i

There is a guy on here (JPA I think his username is) and he is a regular on West of Scotland RSOC site and he ran a Focus RS lump on OFAB I'm sure - it was a grey Mk3 Fiesta and was in PF about a year ago - could do a search and sure he could give you some pointers mate?

I think he broke the car so it might even be his old engine you are talking about? He upgraded to a mk3 Fiesta with Evo running gear!

rog

iTrader: (2)

Thanks, yes I know who you're talking about I saw his Fiesta at Knockhill.
I don't think the car or engine is anything to do with him unfortunately, it was converted by a tuner apparently, and has gone through a few people since, the workmanship on the electrics is terrifying so it can't be pinned on the original builder, but if it did come like that I'd be freaking out! The car itself looks well built, just needs some cosmetic bits seen to.

E980VTJ

sure I read somewhere (could be wrong)that to get a focus rs engine running on standard management every sensor/connection has to be connected or engine will not run is this true

rog

iTrader: (2)

Can't be, thats all I'm saying....!
So now it looks like I need a Mk6 fiesta zetec wiring diagram, a Mk1 focus RS engine wiring diagram, and whatever ECU the thing is running diagram... The car needs another loom, don't know which loom has been used to wire it up but it's not a Focus one, it's either the standard Zetec loom or a fiesta rs turbo one.

E980VTJ

so if the focus rs speedo instruments are dissconected it will still run?

not dissing you but thought I read this in a magazine

E980VTJ

any one put a focus rs engine in another car with standard managment?

rog

iTrader: (2)

It's not running the Focus RS management, the dash cluster is a fiesta 1.6 Zetec and only the speedo works I think, nothing else. I can easily fix it all once I've figured out what bits have been used to wire it up and anything that is missing just run a seperate loom. There are parts of the loom that aren't connected to anything in the bay, and at least two sensors on the engine that don't have anything plugged in, the fuel pressure regulator didn't have a vaccuum pipe attached either?
The engine doesn't know any different what is controlling it so all that antif theft malarkey doesn't apply.
It seems to run almost ok apart from an idle issue, which might be the usual FRS cracked breather pipe or the ISCV, but with the wiring looking suspect that needs to be sorted first.

E980VTJ

thought you was just asking lol what car are you working on?


what I ment was if you were to transplant a rs engine & loom & ecu staright out of a focus into a mk4 escort even with the key and transponder I dont think it will run


obviously I know the engine itself will run with the right management lol its just an engine

Has the car got angel eyes, heard these can sometimes cause problems.

iTrader: (2)

Lol possibly....I'm not sure if they were taken out though.

Yeah ok I know what you mean mate, there's probably some additional alarm gubbins that you need to swap over to to make it work, deffo won't be going on focus management so will have to figure out how best to fix it.

OFAB is years behind in technology. That was a huge downgrade.

E980VTJ

on the running side of things what would be the downside to lets say ofab efi zetec turbo engine and say your choice of ecu,forget mapping and so on but day to day running,

nevsrevs

what gear box is it running? is there a triangle speed sensor plug coming off speedo drive? i have run a zetec turbo on ofab before and made a few looms if i can help?
