Anyone tried a disabler for active fuel management?
1 Attachment(s)
Curious if there’s a benefit at all with use of one of these diablers. Has anyone tried these or similar?

I have had 1 in my 2012 chevy Silverado since buying it new.No problems and it doesn't go into cylinder deactivation.

Thanks Mark. Did this improve performance at all or impact gas mileage?

I bought the Diablo tuner instead. Not much more money and several more features. You can get them refurbished at a good price, see the link.

With that being said the Diablo has tons of great features. I would probably destroy something messing with the wrong file. |

Thanks guys. My 2019 burb is still under warranty so am mindful of that.

That said, the day is coming sooner than later that I’m gonna cam it and be done. I’m sure you already know but on the direct injected gen 5 engines, you gotta watch the carbon buildup on the intake valves. They have had some troubles there. A catch can is a great investment to help keep the valves clean. |

Tyler that helpful info. Thanks. If it’s the case I may get better mpg or save wear on the engine than I’ll jump on a disabler. I know next to nothing about this gen motor. I’ll check into a catch can too.

In my opinion your money ahead to get it disabled. I haven’t messed with any of the Gen 5 stuff but I know the lifters in the Gen 4 AFM systems are notorious for failure, often times wiping the cam with the failed AFM lifter.

Needing to replace a vehicle that was totaled out. Looking at purchasing an older Tahoe if I can find one in my price range. I want to stay away from the afm if can.

Re: Anyone tried a disabler for active fuel management?
we have seen several AFM lifter failures at the shop where i work, usually right around 100 K and yes it wipes out the cam too-permanent cylinder deactivation is what we call it. Jasper sells a calif legal engine with normal lifters on all 8 cylinders, it comes with a program to download in the vehicles computer so the CE light wont come on, it comes with an executive order number (calif smog legal crap) so it will pass cali emissions test. our smog machines will pick up any tune that has been installed-even if it has been removed it still leaves a "fingerprint" on the vehicles computer. you guys that live where you can still have fun with your vehicles are lucky.

Re: Anyone tried a disabler for active fuel management?
Thanks for the follow-up. I never went ahead with an AFM bypass and maybe I should re-visit this issue soon. I'd like the burb to last for a long time.
