Nothing. If you want to get rid of it you need to tune your camaro

Active Fuel Management... L99 Automatic engines only... if your running stock exhaust you wouldnt notice as much now that it has growl the 4 cylinder mode sucks...
I have a predator programmer from my 2008 chevy Avalanche but it doesnt work... Could this be refreshed? or can I get a mail order tune for it so i dont have to buy the unit again?

The predator can turn that off. Modify your tune and set DOD to off and you will love it.

If you're going to manually alter your tune be sure to save a copy of the stock tune so you van revert back to it

You would be modifying your diablosport tune not the stock tune. Stock tune get backed up.

Ok I got you. I thought you were suggesting to alter your stick tune.

AFM does sound like crap on these L99's with exhaust, and it gets even worse with HFC. I think Chevrolet should have made the AFM deactivate when the trans is in sport mode. Wonder if you can do that with a tune....Not completely turn it off, but turn it off when trans is in sport mode?

You can have it tuned out , just contact Ted Janetty and he will steer you right or just do as others have said.........LS3. There is a conversion out there L99 to LS3 but I am not sure what you would have to do.

I recently had mine turned off.

Before the tune, I would tap shift so that DoD/AFM would not engage.

You have a U7194 and if you return your Avalanche to stock you should first update the Predator to the latest firmware upgrade using DSdownloader, then it will work in your Camaro and you can turn off AFM.

You do need one U7194 for each vehicle though.

If you are not happy with the Diablo Tunes or need something other than what Diablo supports, I offer Custom Tunes for the Predator and Trinity.

Ted.

You can do this with EFI Live or HP Tuners. You can even program it to only come on in certain gears.
