Fuel issue 1/4 of a tank and below

Dansc · 05-26-2016, 01:05 PM

Hello,
Just had a tune installed and I am having fuel issues below a quarter of a tank when I give full throttle. Otherwise tune works very well just the clutch is slipping

I have cat downpipes and MSR intake installed.

Did anyone have the same issue and know how to fix it?

Thanks
Dan

Never heard of this before, car should perform the same regardless of full tank vs 1/4 tank.

What tune and stage do you have?

MCarsFan · 05-26-2016, 01:52 PM

Haven't heard of this issue either.be interesting to hear what stage tune this is too

Dansc · 05-26-2016, 02:23 PM

Thanks, running around 22-23psi.
Not sure what stage that is.

Well go to your tuner and de-tune it so it doesn't slip.

What are the symptoms? What happens? Few of us are at 22-23psi with no issues.

Dansc · 05-27-2016, 02:33 PM

Before it was just at low fuel....but now between 240-260 km/h it goes in safe mode and no power anymore. When I start it again it is gone.
Could it be because of the clutch?

I already have a Dodson clutch here which gets installed in the next 2 weeks.

allmotor_2000 · 05-27-2016, 03:30 PM

Who's tune? Safe mode means a DTML or just cuts power and then you can go at it again?

A Shop here in Germany.
What is DTML?

mstmng · 05-27-2016, 07:40 PM

yes you get dtm - DRIVE TRAIN MALFUNCTION
for the safety of your car, it shuts down due incorrect air/fuel mix, when fuel gets low
i have exact same issue, but i try not to keep a tank below 1/4 anytime anyways so does not bother me

Oh perfect.

Get your tuned checked. Revert back to stock tune and see what happens

Dansc · 05-28-2016, 03:38 AM

Yes I get DTML...
Are there any options regarding a different fuel pump?
Also do I need gap the plugs differently from stock? I read it somewhere.
Thanks for the help

Dansc · 06-02-2016, 07:23 AM

I have the error not enough fuel pressure. So not enough fuel is coming through.
So nobody had this issues before? I think in the US you are running leaner tunes but I did not think that it makes such a big difference because I am not running huge amount of boost like others here.
Maybe somebody can comment.
Thanks
Dan
