It's to encourage economical driving. The base 4.3/6speed has an actual throttle response.

Not their place, IMO. Frankly, it doesn’t serve them either. I’d bet it has more to do with EPA rating than anything else.

Makes no difference in the EPA rating at all, The delay is also to protect the powertrain from sudden shock, but moreso to discourage aggressive driving.

I mean, argue against that being their motive, but how would slower acceleration not impact EPA rating?  At the very least, fuel mileage. If it doesn’t though, even less of a reason to implement it. At least let me change it.

Because in the EPA Dyno test you have to accelerate at a certain rate so slower cars have to use more throttle....

Bear in mind only about 30% of vehicles are actually tested by the EPA, the EPA allows manufacturers to self certify. that's how Hyundai got in all that trouble about claiming 40 miles to the gallon in the EPA tested and can only get 38.

the dynos provide all of raw numbers and then they use an equation to get the numbers posted on the sticker. Hyundai took more liberties with the equation then most manufacturers however they were never actually fined by the EPA because what they did was technically not wrong since the equation is up to interpretation.

They're doing it to "protect" their powertrains.

same way the 3.0 makes over 400 lb to torque at 1200 RPM but if you floor it from a stop you don't get full power until second gear. I maintain they wouldn't need protection if you just built it correctly in the first place.

I read and heard 100 things, the comments are hilarious.   No it doesn't add power, no it won't remove all the laziness, no its not a complete tune.

 

What it is tho is what it says, pedal commander. With electronic throttle pedal it changes the frequency making the throttle touchy and responsive.  I have one and its on sport +, it made throttle real responsive( thats it).   I enjoyed it so i kept it.  That with the range afm disabler makes it really nice to drive.

 

 

For sure i will  do a complete tune when places start doing it.  Probably better off buying another pcm, spending the money for it and tuning that one. That way the original was never flashed.  For how the gm warranty is it might be a better idea.

 

On the other hand 5 star tuning has a hand held that now tunes the 5.3 with afm and the 6spd. Only the custom trucks basically.
