my beiges are not supplying enough fuel and i have been offered a set of Ford Racing injectors,injector code (558) which should handle up to 300bhp i have been told they fit straight into the fuel rail by grove garage but would they run ok on my managment and would it need a remap straight away as i have sold my beiges and would need to drive it to get it to the garage to get it mapped if needed

SafeChav

they'll run but obviously on the current map they are going to make it run rich as they will be spraying more fuel for the same duty cycle.

turboben

but these will defo work on the managment as i know cosworths ones dont work properly

SafeChav

that must be down to the impedence of the injector then.......

But TBH its only really an issue if its too low, and even then they work, but you risk damaging the ECU as its basically like putting a piece of wire across the terminals in the injector plugs (a dead short)

turboben

would it still be ok to drive on the original map for a week or so till it is remapped obviously not ripping the shit out of it just normal sensible driving

G2RSR

You should of NOT got that shonky ofab/ofac management

injectors are are a rip off it will do about 5 mpg at over 200 bhp and its around Ł600 to map and thats not perfect because its so hard to map properly

might of cost you less in the beginning but its sure gonna cost you more in the long run

Rick

It probably won't even start!!!

And who are you planning on getting to map it? If it's OFAC, you can't just remap it for any injetor you wish like with Cossie stuff.

Much better to use Mfi and a 5th injector if you want more than 230hp.

turboben

its ofab and i am not too keen on cosworth managment as that is getting old as well its just a cheap alternative for the mo plus i can get the mapping done at grove garage as i get on well with one of the workers there and where did you get Ł600 for a remap you must shop at harrods

at the end of the day i know efi aint the best mangement out there but it is all i can get for my budget as i have all the bits lying around from what i have collected over the years all

basically all i need to know is if the ford motorsport injectors will run on the ofab efi management on the same map as the beiges just till i get it booked in for a new remap cheers

Rick

No they won't.

If you are converting, putting in all that effort, u really should go IAW.

mark-rst

558s (or green tops) are high imp (14.4ohms)

440cc @ 3 bar rated also

turboben

thats the ones are they any good fella

BlueFiesta85

mate i would keep the injectors you have got now, until you can book your car in at grove garage and let ahmed and mark install some of their own arbath injectors for you, as they are capable of upto 300bhp, plus they will map and road test it all for you for a reasonable price mate.

series_one_rst

sorry to but in, cossy injectors wont work on ofab/ofac either then?

was doing a cos management/efi conversion on my rst and got 4x4 standards in at the moment. decided to bin the cossy idea maybe get megasquirt efi stylie management or something of the like.

till then i was thinkin of just bangin a ofac ofab ecu on to get it running and run the engine in.

turboben

right i have been talking to mark and pudding at grove and the 558 injectors will work not a problem but he reckons the best route is to forget about the ecc managment and cosworth management and use lancia parts as aparently the idle and so on and so on will be better

turboben

na cosworth injectors wont run on ofab/or ofac

BlueFiesta85

i would take their advice mate, thats the good thing with mark and ahmed. even with the setup you have, they will still say get this, get that coz they know what their talking about.

©hatter Box

just let grove sort it out for you m8 as half the people would give you the wrong info any how you would need to change your map sensor any how m8

ahmed goes goes for green webbers or the beiges webbers for ofab but there like rocking hourse shit he gets hes new injetors for usa now

CosRush

is your car running know fella when you gonna let a big chatter off outside my house

turboben

na mate nothing yet just loads of hassle its all in but it sounds like its running anti lag when its fired up lol

steven botes

probably wont idle

finally fitted my 500cc's today (old ones are std ERST Blues) and spent about an hour just getting it to idle!!!

had to drop my injector ms to about 1/3 from the blues and still have issues with bad idling , will try dropping fuel pressure tommorow and advancing idling to 15'

The Gotech i have fitted myself is a pleasure to use , pity your pricing!!!!
Also bought the injectors from Gotech , a steal at ZAR400.00 each vat included

orion_rst

What injectors do you recommend when aiming at over 300bhp? If my calculations are correct they should be about 680cc (x4)

But where can I find these high impedance injectors that fit straight on the Fiesta fuel rail?

I was looking on a website www.injector.com and they have 2 types of injectors for sale... the American type and the Japanese import type? Is the American type the same as they use in Europe?

Fiecos Dan

4x 380cc will be fine on 300bhp.

orion_rst

I'm aiming at over 300bhp... of course not now but I want to do it right the first time

Do you know about any injectors that fit straight onto the Fiesta fuel rail?

©hatter Box

if you want over 280bhp on ofab you need these

orion_rst

So basically any Bosch style high impedance injector will work on the Fiesta EFI Manifold?

As I said on www.injector.com I saw two types of injector, the American style and the Japanese import. Is the American type the same as the Bosch type?
