On dyno...for tune..i weent to amator shop ...it has been tune with 10psi fuel psi..now car run and stall after 15 min..i lowered psi,now run and dont stall but i misfire on high rpm(like cut off)...i backfire...seem a combustion problem...im rich...
If you want i can send you a datalog of my aem ems v1!

 

The guys told me ,that i boost 8-9 instead the 13 i was suposed!

 

You may be getting spark blowout, tighten your plug gap. If your tune is bad, fix that first instead of patching it by regapping.

 

I dont know,the guys tokd me to fix the misfire and come back...but can my 10psi too much of fuel pressure be the problem?i just dont know i should go back and see the guys..

 

Sounds to me like you need to find a better tuner. You should try to check in your local forum and ask where everyone else goes to get tuned in your area. Look for someone with experience with AEM and S2000's.

 

I had 3.8 at 10 psi.
U r probably a bad tuned,belt slip or boost leak.

Tightened the bolt tension, not soooo tight.
Check all the connector n tight the clamp.
Or maybe get a new belt.
The goodyear gar something belt i forgot.
Also,a good tuner would of be much better to end up with.

 

How tight is the belt? How much can you turn the belt?
Definitely get a new tuner. Sounds like they have no idea what they are doing.

You either have belt slip or boost leak. You have an after market map sensor right?

 

Nope, I'm on a 4" pulley and am making 8 psi at 8k rpm.

What rpm do you make the 10 psi?

Hey, OP, still running the after cooler or intercooler? You lose a few psi if you have an intercooler.

 

I had at 8k rpm
