AFM TURN OFF
Hey Guys
Other than voiding my drive train warranty, Are there any short or long term mechanical problems that might arise if I tune out the AFM? It is driving me crazy at slow speeds under light loads!!! |

You should have no problems what so ever.

I'm about to sell the car over this problem. I drive in manual all the time keeping the rpm's up so it doesn't shut down cylinders. I talked to the dealer about it and he said GM would have to initiate a fix before they could do anything. Anybody know what can be done. Thanks

I turned AFM off in my Silverado about a year ago. Much more enjoyable to drive, it isn't ever coming back on. Making a small block chevy run on 4 is about the most idiotic thing since the Caddy 4-6-8. I'm sure the tree huggers will love the .1 th increase in mpgs, but the reality is if I wanted a 4 banger I would have bought one. |

I am taking my car in to a shop to have a Pfadt sport suspension and Kooks LT headers installed and when they do that, they are going to dyno the car and do a tune including shutting off AFM.
I know this will void my power train warranty. But me wants. I bought the car strictly for the joy of driving it. I'm adding more joy. Ya gotta pay to play. |

When I had my supercharger installed by MIKE NORRIS MOTORSPORTS up in Indy he turned my off on my L99. It's a different car now. I too use to keep mine in manual mode all the time to help control the noise. When I installed my headers and 3" exhaust it magnified the problem. Find a good tuner close to you who can hook up to your car and and turn it off and while you're at it just go ahead and throw a tune on it. You'll love it. PM me if you have any questions I can help with.

Is it really that bad? I have an LS3 so I wouldn't know but is it that annoying? What does it do to annoy you guys? Does it not switch back fast enough to 8 cyl mode?

Also, the AFM really doesn't produce much improvement in fuel economy. My understanding is that it might add only 1 or 2 mpg. I believe AFM was only put in the car by GM as a gimmick to bypass the gas guzzler label for the car. I am going to have the AFM turned off when I get my headers and a tune. |

This also doesn't apply to the OP since he's probably already got his answer. Last edited by mlee; 04-04-2010 at 08:18 PM. |

We did and it's so much better! It was driving us nuts. Besides, we didn't buy this car for the gas mileage.
