Fuel cutoff at 190?

| The freeway tonight was absolutely deserted. The wind was blowing from the back and i hit 190 in no time, but then acceleration sharply stopped. What exactly happened? Was it some kind of a safety fuel cutoff mechanism that kicks in at that speed? I felt a bit of a bump, and for a brief moment thought i may have popped a tire, which at that speed woulda been really bad news! |

hahahha
i see u are suffering the curse of the factory ECU settings.
it's to "protect" the engine. For it to be under warenty, the drivetrain should not be subjected to some conditions. They make sure that the drivetrain (engine & tranny) is not subjected to such conditions.... You can go to a few performance stores and they could edit ur ECU software but that costs money. Not a good idea unless u wanna race ur car. |

There are factory instaled rev limiters and speed limiters. Rev limiters cut off fuel delivery to the engine when the engine revs into the redline area. Speed limiters cut off fuel delivery to the engine when a pre-defined speed is reached.
What likely happened is you hit the max speed the speed limiter allows for.
A word of warning: make sure you check the speed rating on your tires before trying to hit record land speeds with your vehicle. Here are the letter speed ratings for tires, which should appear on the sidewall of your tire:
R-106MPH
S-112MPH
T-118MPH
U-123MPH
H-130MPH
V-149MPH
W-168MPH
Y-187MPH
Z-187+MPH |

#1 - you're racing your car all the time and you don't even know what an electronic limiter is?
#2 - I cannot believe you're posting this less than 2 days after your "cop" incident. You're just begging to lose your license. |

I agree with you Aaron. This guy doesn't deserve to have a liscence in my opinion.
You put yourself in danger and you put others in danger and expect the cops not to do anything. |

Seriously d!abolic, have you got nothing else to talk about? Oh wait.. Thailand. :rolleyes: I wouldn't be surprised to see a "I got in a high-speed accident and survived but the people I rammed from behind didn't" thread from you in the near future. |

Don't get me wrong eh d!abolic, my friend usually drives his old Z28 between 150-200 on the highway. The difference is that he's put about a thousand clicks on it and knows its ins and outs like the back of his hand. The guy does some dangerous but nothing that would ever make him lose control of the car, he's had it for over 5 years and never been in an accident.
You on the other hand are going way over the speed limit, don't look carefully enough for cops (when there's nobody on the road except one car following you, IT'S A COP), don't even know that your car is electronically limited and don't know the speed ratings on your tires or how to tell when one of them's been popped.
To put it bluntly, you're driving your car like it was stolen, without any regard for your own safety, the safety of others, or the mechanical health of the car! It wouldn't surprise me if you've already wrecked your suspension and shaved 3 or 4 years off the vehicle's lifetime. If your insurance company knew how you drove, your rates would triple. In short, it frightens me that I'm sharing the road with people like you.
#1 - read your car's manual, and #2 - get yourself a lot more driving experience before pulling like that. |

#3 stop trying to overcompensate for a small penis on the road, and go risk your life on the racetrack.
at least there it will be you who dies, and not some innocent in your way. |

meh...I'll leave my feelings on speeding out of this...suffice to say, hopefully this was when you were sober, on dry pavement, with no one else on the road, in a well-maintained vehicle.
many cars have fuel limiters built in...before I had my Talon, I drove a Focus...fuel cutoff was around 172 km/h, I think. It could be shut off with a chip upgrade or ECU re-flash. Not much point in doing that, IMHO...because when are you going to need it? |
