The AC compressor has a magnetic clutch that automatically disengages the compressor during WOT.

Every once in a while my 7at downshift is delayed, which turned out to be bad yesterday as i was doing 40mph, and downshifted fom 3rd to 1st, because i thought i didnt hit the paddle all the way, however it was just being delayed....sounded like my engine was gonna splode! dam.

... Don't worry about it. The 7AT won't let you downshift past the rev limiter.

I get those occasional delays when downshifting too, VERY annoying. Luckily upshifts are never delayed, THAT would suck.

I've bounced off the rev limiter a few times. Well, you don't really bounce off of it. I don't really see it as something to be concerned about, the rev limiter seems to be set pretty conservatively. When I was on the track, I was pretty much shifting at the limit for every shift. Even on the street I shift at red line a few times a week.

That makes me feel a whole lot better. Thanks.

It also won't "queue" up a downshift if the downshift would be past the rev limiter, it simply ignores it. Of course you still might get the delay which will queue up multiple downshifts if none of them will cause a shift to hit the rev limiter.

I'd love to know what that "problem" is, and if a tune can fix it. I know my tune from Uprev didn't change that at all.

Yea i have no idea if you can fix it....

i just like downshifting a gear before i accelerate so i can hit the 4500 rpm range, thus getting rid of the acceleration "delay" present when accelerating in auto mode...

however yesterday i double down shifted which i assumed couldnt be good....

I've never actually hit it. Where's our rev limiter set at?

@ 7,500 (where Redline starts). It might be 7,600 actually, but it's pretty close.

Live a little!

I've taken it to redline, just never hit the limiter. I guess it must be slightly past it.

I did a few tests on the way home, and on the 7AT, 7500 RPM is definitely the where the rev limiter kicks in. This was with my Uprev tune, I didn't think to try the stock tune, but the rev limiter was supposed to be left the same.

In my completely uneducated opinion, I don't think there is any real difference in engine wear if you are shifting around 7k rpm and 7.5k rpm. They put the rev limit at 7.5k rpm for a reason. Someone feel free to disagree with a more educated reason on why this isn't correct, please.
