Hello everyone, I’ve got a question about the AFM disable on my 2018 Silverado. The AFM used to disable on my truck now it goes back into enable mode. The only thing different is that there was a recent update. Looking for any advice or experience. Thanks

How did you disable AFM? With a tune?

If your ECM was re-flashed by a dealer, you lost you tune forever.

If the dealer did an update, your tune is lost. You should always return the truck to stock tune before taking it in for any type of service for this exact reason, sorry to say. You'll have to redo your tune.

So trying to understand this cryptic post.... Sounds like you had AFM turned off with your tuner. The tuner was updated and now AFM is active. Is this correct? I suggest returning your truck to it's stock tune and the reload the Diablo tune. If you still have issues contact Diablosport.
