Underfueling Problem- help needed!

[Scamper]

Right lads i got the car dynoed on sunday at the show, and john at wcp told me she is underfueling, he said it aint good for the car , and that constant hard driving could resullt in a blown engine.

Basically i wanna no how you would go bout sorting this properly, the car is running perfect if not driven hard, but wanna get this sorted, so can drive her on

Wat would i need to do?
Fuel regulator?
New fuel filter?


Thanks in advance lads

Up rated fuel pump and a decent map from Westward.

some sort of fueling controller like apexi neo safc2.or you could go with some thing better like an emanage.or more expensive a standalone Ecu

first,you need to tell us exactly whats in your car at the moment

how badly under fueling is it? a print out of the afr's from the dyno would be handy

[Scamper]

I dont have a print out, but wen you put the foot down he said the dyno should read from 10.0 dropping rapidly as you increase throttle, so goin from 10.0 down to around 3.0 at full throttle, where as wen i put the foot down in my yoke it goes from 10.0 up to 17.6 at 5500 revs!

Sorry if that means nothing or isnt explained right but dont know much bout this at all!

I agree with Mick here,had 14a once with same problem,had bigger turbo on it but uprated pump,injectors and seen westward,he mapped the power fc and it was perfect then.

I have a standard ecu thats chipped, the car is boosting at .7 bar, have a t28 turbo off an s14a in her, its a black top aswell lads.

I had a t25 that was boosting at 1 bar but then changed turbo and actuator in june to a t28 and dropped to .7 bar.

Throw dat chipped ecu in de bin if it came from jap land!! They blow engines in de long run as they are made to run on much better fuel than wat we have and they usually only mess around with your ignition timing which is not good if not checked!! Put a good pump into it e.g walbro, sytec, a good pump is a good investment no matter wat anyone will tell you and get it back on a dyno, i wont tell u where to go but my advice would be TDP as i work there and i no the work is top notch!! Hope iv been of some help
