Fuel Pump?!

[sl33per]

just changed the fuel filter, and it still keeps surging and cutting out and stalls, any ideas what it could be?

[Topaz]

recent back story please

[GTS-t VSPEC]

Not alot of info to go on, but it could be AFM related, you sure you don't have a boost leak ?

[reNEGaDe88]

Did you put the fuel filter in the right direction?

+1 for AFM

Im getting sam problems Stalling when stopping, Hitting around 5000rpm car feels like its dying no fuel / to much air!

got a new High flow on it running 1 bar.

Just bought a SAFC / Fuel Pump for a tune hope it works.

+2 for air flow meter

Sounds like you're hitting R*R.. 1 bar through a hiflow on an untuned stock ecu.. hello rebuild

[RICCA]

Yer but hardly thrash it its running ok was a brand new turbo, so need to be warn in (not blowen lol) maybve the ARC are out will find out monday when i get the tune.

[reNEGaDe88]

Yeh as budda said. Don't run the hiflo turbo and 14.6 psi of boost. Ur stock ecu will not be able to cope. Ur car will get too much air, ping, detonate and pop a rod out of the engine block = rebuild

[bubba]

The ARC? you mean the AFR's?

I'd wind the boost right down (even disconnect the actuator) until you get it tuned.. it's clearly flowing way more air than the ecu can handle!

[RICCA]

Installed my SAFC last night, tune on monday,

actuator is D/C

Well at the start get the car dyno to see what psi it was running it was at 24psi lol

So re-connect boost line to stock * then placed on my bar.

Air was ok Had new Sparks Place the guys put thos New Tips ( which i think already blew so going to try NGK's

Checking AFM and Fuel Pump also Coils this week .

24psi?!

When you disconnected the actuator did you just pull the hose? or disconnected the arm from the flap?

Are you saying that with the actuator disconnected, it's still running 1bar?

As for sparkplugs.. NGK BCP6ES-11's, gapped down to 0.8 if needed.

[RICCA]

Discounted from the flap cause first.

Still running one bar,

Yer the turbo was higflow and i put it on the dyno it was out of wak! running over 20psi , so fixed it.

[bubba]

Hmmk, should probably stop whoring this guys thread now

[RICCA]

Nothing has changed lol ,

Well might be good info for himself.

[reNEGaDe88]

Did you mean disconnect the waste gate actuator so that it is always open = car will run max boost of like 6psi at full rpm, cause the gate is always open. Or disconnect the hose so that the gate stays closed and runs max boost ~ 24psi....
