fuel presure regulators???

[nozaroc0]

i have the 2.0 zetec in my car but it is running lean. i have been told that this can be cured by fitting a fuel pressure regulator, altho i have no idea which one to get or how to set them up as they are all messured in psi or bar and i wouldnt know how much or little to adjust by.

 

anyone know anything that might help me?

If you're running the correct ECU, injectors and MAF sensor for the 2L engine then it shouldn't be running lean. This would point towards a problem that should be resolved rather than hacked by upping the fuel pressure (which isn't the solution).

well this is where i get a little confused as i have modifications to the engine. it is a 2.0l block with rs1800 head with fast road cams (designed for the 2.0l) 2.0l fuel rail and injectors and the HO stamped inlet manifold, full exhaust inc 4-2-1 manifold.

 

at rolling road at fordfair i was told it was running too lean as it was only 140bhp. but with the mods shud be closer to 150-155.

 

so i suppose i shud probably need a re-map/chip before anything else, but i am told as a temporary measure a fpr is the answer.

 

altho i have only been up an hour so none of the above could make any sence to anyone else..

You haven't said which ECU you're using.

[nozaroc0]

its a 2.0l DESK ecu

[Stu]

And what MAF sensor?

[nozaroc0]

again from the 2.0l

Alright.

 

So how lean is it running? How did the rolling road operators decide it was running lean? Sticking a wideband sensor in the tailpipe is not an accurate way to measure it really.

 

For the spec you detail above, i'd expect it to be no more than 140bhp, and perform generally worse than a standard 2L engine below 4500rpm.

i would double check if the parts your using are from the same car as that helps stopping the lean problem.... only thing i can think of is why your running lean is your standard fuel regulator is faulty or your injectors are faulty and you need them checked/test

[nozaroc0]

ok, i think i need to get to a tuner that knows wot they are doing then.

 

anyone know of any tuners in or near cornwall? preferably some one thet specialises in fords??

I would get the injectors refurbed, I seen and had no end off running issues with poor injectors!

it does preform realy well i think, tickover is about 950/1000rpm. revs pic up well and has a sort of 'boost' at 3500/4000rpm.

how does refurbing the injectors work then? is it possible to refurb them myself? or worth buying a set that have already been refurbed?
