I have a 2008 with the spartan tuner on it and running the 310 tune and when I started racing and I put it to the floor and I started good and the it seamed like that motor started to die dose any one know what this is and how to fix it? Thanks for any advice

 

What is your fuel rail pressure doing as this "dying" episode is happening? My bet is its time for an AirDog.

 

That's what I was thinking and it drops a lot

 

Time for an Airdog or Fass or sure.

 

I'd be more apt to take a look at your boost pressures, egts, etc. You might be defueling.

If I recall, according to Spartan, the factory intake system is perfectly fine until you tune to the point of changing injectors, turbos, etc.

Bear in mind that if you are "racing" on your stock drive train, your 310 HP tune will help you find all the weak links in it sooner rather than later.


Besides that, why are you here asking that question? Spartan has a website and is way more capable of providing info regarding their system then most anyone here will be.

 

Because I haven't set up my account on there web site yet and in know its not good on the drive train I was just seeing what it would do

 

what are your fuel rail pressures?

 

Sounds like defueling to me. I have an H&S but I imagine there is a way to set the refueling parameters on the Spartan, maybe one is set too low. I once had my tranny temp set at 130 degrees, oops.

 

I dont believe the 310 tune has any defuel safety parameters and the end user cannot adjust them as of yet. The OP poster is likely dropping rail pressure due to the LP pump not being able to keep up.

 

can you watch the rail pressure with a black maxx?

 

It drops below 3500 psi but then at times when I hit it hard it gets up to 27500

 

How long has it been since you've changed your fuel filters? might just be starving through the plugged filters.

Good luck and let us know what you find.

I just did today so hopefully that will help

 

What is the boost/rpm/ fuel rail pressure when this happpens, 3500 is no where near enough fuel pressure even at idle.

 

whats the name of the gauge to read fuel rail pressure?
