What Does Fuel Cut Sound Like?
I am having a problem when my car reaches around 12 PSI, it makes a weird noise and looses power.
The noise kind of sounds like the rev buzzer, but broken up. I am wondering if there is something wrong with my FCD? |
I've hit the fuel cut before with my FCD disconnected. The engine sounds like this:
rrrrrrrrRRRRRRRRRRRRRRRRAAAaaahhhhhh,fffft,fffft,f ffft,fffft,fffft,fffft,fffft,fffft,fffft,fffft,fff ft,fffft. :) As far as the buzzer sound, I can't help. |
as ya said fuel cut is just a dramatic loss in power. depending on the computer it cuts every second injector pulse. but you would have the fuel cut defender, would u not??? i'm assuming when u say weired noise, you're not talking about detonation, which would also create a dramatic power loss.
what i want to know is why don't they use ignition cut. i thought fuel cut would cause detonation? i'm getting fuel cut at 17psi (my aftermarket computer is set at 17psi). my turbo is set at 15pounds but creeps at higher rpm. i suggest you keep away from the fuel cut until everthing is sorted out. |
Yep.. I figured it out!
I was running too much boost (.93 bar) Lowered it to .83 bar. Runs lots better! |
