......be used on a Zetec Turbo, piggy backing the FRST ecu with Cosworth Injectors? Any good/bad things to note about doing this?

Thanks

I dont think so. But it does add support for extra injectors...

[Fiestasi-Andy]

whats wrong with http://www.motorsport-developments.co.uk/

[StreetDragster]

Had a quote from them andy for their high flow injectors and live map ecu and i'm just trying to see what other options are avaliable, like i could probably get some 2nd hand cosworth injectors easily and then the overall package would be cheaper.

Thanks

Yes it can be used. If i'm wrong i'll never post in the Tuning Forum again!

Ok, i finally got through to the technical department at Storm Engineering, the UK distrubuter for Unichip.
The bloke said that basically, that configuration wouldn't work because the Unichip doesn't directly control the fuelling of the engine. The unichip actually intercepts the signals from the Throttle Position Sensor (TPS), Crank Positioning Sensor (CPS) and the Manifold Absolute Pressure sensor (MAP) and then adjusts the signals to fool the ECU into thinking that the engine is at a different stage in the map than what it actually is and this allows the Unichip to richen/lean the fueling accordingly. The problem being the the FRST ecu will still be driving the injectors, which are high (16 OHM) compared to the low (2.3/2.4 OHM) Cosworth injectors and it would burn them out. He also said that i will find that, generally speaking, most cars use low impedance injectors to get quicker opening and closing responce times, but then have a resistor pack built into the circuit somewhere, which give the effect to the ECU that High Impedance injectors are actually fitted.

So, now i need to clarify some of the other ideas i've heard/read about.
1) Can Webber 803's with a Cream Pintle be used on EECIV OFAB management due to these particular injectors being the correct resistance
2) Can injectors from a Racing Motoguzzi motorbike be used with the FRST management? If so any more details, part numbers, ideas where to buy from etc?
3) Can a resistor pack be used on Cosworth injectors, if so any ideas on the correct resistance required and where the resistor should be fitted? I'm assuming that it would go in the +12v wire to each injector.

Anyone help with any of these points? I know motorsport developments off high flow injectors for EECIV management, but they are not cheap and i'm trying to reduce the cost of my engine management package.

Thanks

Yeah, thats why I said it wouldnt work. I should have elaborated further but I had to go back to work!

could cozzie management not be used?

1) If they are the correct resistance then yes. However I don't think they will be 803s, maybe a similar flow rate though. This week you will be mostly needing INJECTOR FLOW RATE DAARTA... http://www.fiestaturbo.com/adrian.t/injectors.pdf 0 280 150 737 is prob the ones you'll want.

2) Yes! BUT they are side fed and therefore require the Zetec fuel rail to fit, FRST ones are end fed.

3) Yes, not sure on the details though. There is a chap on here called Bob The Builder who's running Cossie injectors with EEC-IV. He's not on here too much so I'd drop him a mail and see if he can help.

Thanks everyone, looks like i've still lots more to read and learn

Thanks again

New Thought-

Has anybody sucessfully used 8 injectors on the FRST inlet manifold, using 8 standard FRST blues, two standard FRST fuel rails with two standard FRST FPR but one, uprated escort cosworth pump?

Where would the second set be mounted for ideal atomisation? upsteam of the standard set? down stream? same place but on the 'other side' pointing at the standard ones? etc etc, any info at all.

Here's my train of thought that got me to this.
Standard Frst injectors sell for next to nothing, like £10-£20 for the set of four. I've also seen fuel rails and stuff for sale on here cheap, and, worst case, they are not that expensive from Ford. If i could retro fit they somehow onto the standard inlet manifold, and i had a Unichip fitted, it could drive the additional 8 injectors, giving all the benefits at tick over and low speed of small injectors, but with the extra fuel supply needed at high rpm.

This sound like a good idea or not?

Thanks

Matt

P.S anyone got any pics of the injectors mounts on the inlet manifold, preferably removed from the car?

Yes good idea, will save money.

[StreetDragster]

Plus, at a later date 4 or 8 beiges could be added if more fuel is needed. Maybe this idea would start making zetec turbo'ing cheaper. think i'm going to research this idea a bit further, becuase i like the unichips additional features, like being able to map in nitrous, launch control, dual maps and stuff like that.

Thanks

I used to have a uni-chip in my car when i had the CVH engine, i ripped it out and went with Motorsport Developments

I "personally" found the unichip to be a very bad chip and also did not help the mapper of the chip was not too great either.

But it was not what i wanted, i wish i never had it fitted, a lot of money for the same kind of chip everone else has, nothing special IMO

[chumkila]

... so everyone has a Unichip on their Zetec Turbo?

[Bob The Builder]

Hi guy's,just got my computer fixed (5 weeks it's taken )so i can give a reply to adrians comments.My car used to run on cossie yellows and a 195 chip (ofab) but they were changed to a custom superchip and beiges when my car was rebuilt by the previous owner just before i bought it,he said he had no problems with it running the 195 and yellows.But i also have two friends of mine that run the same combo,one of them runs the 195 chip (ofab) and cossie yellows that were on my car before the rebuild and has had no problems with it.Also another m8 has a frst running 195 chip (ofab) and cossie yellows at the minute with no probs,and has had one before with that combo with no probs.Thats not to say that it is the correct thing to do as people who have a far greater wealth of tuning knowledge than me have said otherwise.I personally don't know myself,but i always thought that if i was doing it myself the EEC-IV equiped escort cossies blue injectors would maybe do the trick as they run off the same type of management as the frst.Does anyone know if they are the same ohm rate as the frsts blues?Help please as someone is bound to have thought of this before.

why not just get a chip and injector package from Ahmed bajoo / fiesta frenzy to keep the std management. at least they are tried and tested and at the end of the day why risk knackering a new engine for the sake of a bit more cash.
