Hitting fuel cut

[my98GST]

I'm on 16lbs of boost wg actuator only. My mods are. td06h 20g, 550cc injectors, stock fuel pump for now, injen intake, fmic, 3" turboback... I have a 255lph on the way.


I have an safcII and I'm hitting fuel cut. I need to add some more fuel to keep from hitting fuel cut. Is there anyone or anything that could give me some numbers to program in so it will run a tid bit more rich in 3rd, 4th, and 5th? 1st and 2nd are fine at WOT but in 3rd it hits fuel cut.

I found a base tune for an e316g, 19psi, 550cc's, with a 255lph, but I figured if I put those numbers in it would lean me out a lot mroe since the 255 would be flowing a lot mroe fuel..

Fuel has nothing to do with fuel cut. The 2g factory ecu will cut fuel when it sees more then 2.55g/rev airflow.

You're confussed with the term fuel cut, fuel cut occurs when air count is too high not when you're running out of fuel, adding fuel via SAFC means you're increasing air count therefore will trigger fuel cut even earlier. What you need to do here is to tune with a logger and lean out the safc but before you do that, you need to run a thorough boost leak test. All of this of course only apply if you're truly experiencing fuel cut and not fuel starvation.

I dont' have my logger in my pocession. Damn g/f also has a GST and shes being mean to me and I cant get it right now..... So I actually need to lean my car out? I was thinking about for Idle -15 then -5 or -10 across the board for starting out and then for high -10 across the board. Just for a base.

I also have no boost leaks, I've already done a nice boost leak test.

Personally, I wouldn't really go taking out fuel without a logger to exactly what effects it having. The car could feel fine on the butt dyno, but could actually be knocking like a mug.

Octane booster I did -15 on low 1000 and then took -10 out every where else and on my a/f gauge its still showing 3/4 rich under wot, but atleast it took my fuel cut out... I'm going to go push the girl friend down some stairs and swipe back my logger in a little while .
