I can not get this car to allow me to keep in the throttle every time I try to it reaches just under 1 bar it cuts out almost like a fuel cut or somthing. This happend on twins now happening on single, boost climbs hits just under one bar car jerks and pops. Is this ignition?is this fuel?whats up?It even has done this with different maps.I just want to enjoy my car before the winter gets here,and I'm two minutes away from throwing the damn thing in the trash.has any body else experienced this?

 

It sounds like your hitting the rev limiter. The only other possibility I can think of is that your running way rich, when I changed to 1200cc injectors and was still running an M2 computer, that thought I had 850 secondarys, my car would go maga rich when I got into the boost and fall on it's face.

It's not the rev limiter this happens at 5900rpm's.I.m also running maps that are posted. It doesn't fall on it's face it seems to cut out like a fuel cut or or rev limiter.

 

If you are using an external boost controller then you must also turn the 'boost setting' up in the PFC via the commander as it will cut fuel 2.5 PSI past what the max boost is set at....

(if memory serves me right)

Check your manual about this also.....

I have no boost controler right now but I'm going to put a nice manual controller that I have,right now I have the wastegate set at 14 lbs.I will try what you say and let you know.thanks

 

Problem solved THANK YOU

 

How did you solve it???????

 

Did you raise your max boost??? If so to what?

 

I put the boost to 1.85 and 1.75 and duty cycle at 80% and 90%.I will try to lower these gradually to see where it starts to cut again,but it runs fine now. I will not be putting the boost controler on until I put in the secondaries then I would like to run 17 or 18lbs.
