seriously, you rev the car up at a light to show off and you end up sounding like a douche cause it sits there whining for 30 seconds(exaggeration)

 

you sounded like a douche when you reved to show off in the first place

j/k bro!

 

hhahahaahahaaahahaaha

 

Burn off any excess fuel. To stop it, tap the pedal once. It'll settle right down

 

Get a lightweight flywheel and you won't have to worry about it.

 

Why rev at the light? I rather let them show off like the douche bag, then get beat .I even give them a headstart usually because its so much better to PASS them then to just be ahead of them the whole time. If you take them right off the line, then they will stop and act like they never wanted a race.

 

Actually it has more to do with the weight of the flywheel. This was a design to lower emissions by making sure that any excess fuel in the engine is fully burned.

If you want it to stop... get a lighter flywheel.

 

Actually as per GM, the flywheel was lightened to reduce the load on the engine as it already has the supercharger to turn while accelerating and starting. Well actually let me take that back, I have seen articles which quoted GM to have said that, so it could have been wrong, but it would make sense. Also, what you were saying would make sense as well.

 

sure... I'll believe that our flywheel is lighter than the stock ecotec unit... but it could stand to be lighter so the engine wouldn't hang onto revs.

 

Yeah, I edited my post too man. I bet you're right; it's just lighter than the other Ecotec engines, yet still not actually "lightweight".

 

but i think they wanted gm wanted to hang on to some of the rev for inbetween shifts the higher the rpms the faster you will go

 

i noticed this too.. even in everyones videos of them revving their new exhaust..

 

it's a emissions thing, it is done by the throttle body, not the flywheel.

 

what happens when more air is introduced into an already running engine.

it revs up.
what happens when a throttle body is stuck open while running, it keeps that rpm.

what happens when a tb is slowly closing?
it slowly drops in revs.

 

hey just what i heard from the dealership they said it was normal

 

wrong.

as far as elimination in hpt, i have no idea

 

+1 - exactly what i was coming to post.

 

hahahahahahahahaha

+1 rep

 

Hmm... possibility... out tbs are electronicly controlled. Has anyone looked at the movement of the tb when someone revs the engine when out of gear?

Maybe the tb just is closing slowly b/c it's electric. In that case perhaps it could be tuned to close faster.

 

As for HPTuners as mentioned before, I read a thread previously on this same issue and someone assured that HP Tuners will get rid of this.

 

x2^^^

HPTuners does not support hardly anything as far as the throttle body is concerned except for changing the recognized square area of the blade.

 

Id love to know if this can truely be fixed with HPT as someone in my area has it now.

and id love to ditch the slow rev drop.

 

You may be able to change coastdown spark and see if it does anything. I wouldn't hold your breath though.

 

lol agreed

 

so your in the "lighter flywheel" boat witt?

seems like 2 schools of thought in this thread. but you know your **** so gimme your 2c
