Just something to take note of. Don't know if anyone has an explanation for it. Say if you have the car stopped, foot off clutch and obviously in neutral. You can rev the engine with pretty quick throttle response.

Now if you were driving down road, through it in neutral with foot off clutch and tried revving it, it is like a dog. Horrible throttle response and doesn't really rev at all.

But if you roll like I describe above, but depress the clutch while revving, it revs like you are at a standstill with foot off clutch. Nice, quick response and roar.

Curious why the car doesn't let you do this while rolling in neutral without the clutch depressed. Anybody know?

Is rev matching turned on?

No it's is turned off. Did not try it with it on, but shouldn't matter. I'm sure it isn't just me. Follow my steps above and other members will notice it as well. Don't know chevy's point in limiting revs when rolling in neutral with foot off clutch, but yet they do.

I did notice the throttle response makes it challenging to heal toe. Not sure why the throttle is so numb.

I think I know what the problem is. C7's have a special requirement that you must not wear your work shoes while driving such a beast. If you are in the possession of these shoes, you must find a replacement as soon as possible! LMAO

What mode are you in? I believe the driver mode affects this greatly. Try the same test in track mode?

I can attest that track mode wakes everything up

Thanks. Was on sport mode. I tried in track too and didn't make a difference. And for other posters above, this has nothing to do with heel toe. If my foot wasn't a size 13, I wouldn't be heel toeing with car in neutral and foot off clutch. I rev match myself all the time. I press in clutch, rev, downshift, all is good. Engine is responsive and revs quick. But like I said above, if you put it in neutral, let clutch up and say are coasting to a stop, whatever, try revving it with clutch fully up. Thing won't rev or so there is no misunderstanding, the rev is night and day in terms of quickness/responsiveness.

Just go out an try it

Interesting..I'll give this a shot next time I drive.

I agree, I noticed that too. I still think the throttle response, even when downshifting is numb. Track mode is better but depending on the road, track mode with MRSC is just a tad too harsh. I will get lazy because rev matching works so well.

Rx will have their throttle body out soon for c7. They are going through final testing. About 10-15 more hp but more importantly the throttle responsiveness is supposed to be a huge improvement. I just have to make sure GM/my dealer doesn't say it voids warranty.

But this throttle issue when coasting in neutral with clutch up, has something to do with computer. Why I have no clue.

Some engineer somewhere decided this was the proper way to program the ECM, no idea why..... I think Diablo lets you program around this.
