7AT throttle lag

CSGLEON

Well.. I was just kinda confused! On my first test drive "7AT" coming from an exterra.. Obviously there was a major difference!. [that being said] I have friends with fast cars! 2008 vette.. 2006 vette.. Ls1 gto goat. 2012 camaro ss. I have driven all of them! But the responsiveness of my now new 370 seems laggy. Not to bitch and complain... I'm just kinda not used to the trottle body being wide open and the lag. This is just my opinion of course! But the lag sucks. So I have been playing with triptronic and it feels a bit more sporty. But I thought the vvel was going to eliminate lag..... Guess not

There's electronic lag that a tune can take out

I think (correct me if I'm wrong) that your lag issue is when lets say you're cruising at 50 and you need to mash the pedal to overtake someone, and there is lag until it kicks into a lower gear?


If that's the issue, you're kinda SOL, just build that into your driving time

^^^How I'm interpreting it too.

@OP: If you want good response, drive it in manual mode and downshift before-hand. There should be practically no throttle lag in gear (I can't discern any while driving hard at least).

If you're driving in auto mode, then what you're describing would be better put as transmission lag. The Z has a conventional automatic that still takes time to shift despite being pretty well tuned imo. You could try driving in M for a while, maybe get used to it. Eventually you'll find it more natural and enjoyable since driving feels more direct.

I read every post to make sure I wasn't going to double post but yes, if you must, THIS.

The 7AT increases valve pressure across the board when in M. That is why it'll jerk you around quite a bit if you haven't learned to feather the gas during certain shifts. It acts much like a manual. But that is also why the shifts are a little quicker and firmer.

And don't forget, ALL 7ATs are equipped with DRM (Downshift Rev-Match) regardless of having sports package or not.

Suffice to say, after giving M a shot a few times and getting adjusted to it I drive M all the time now. No, it isn't a manual. But it certainly acts like it. And to get a smooth drive you have to feather the gas like a manual. Kinda crazy, but it;s true. And for arguments sake, yes, I've drive quite a few 6MT 370s now.

And even though people hate on it because it is still a standard auto, what everyone fails to realize is that it still performs. I could care less if it a twin-clutch or PDK or DSG. All it means to me when someone says "It isn't a twin-clutch" is that they need acronyms and F1 car technology to be happy with their VW Golf even though there is little to no difference and few people track a Golf to the limit where that 16ms actually makes any impact on their lap times. Give me a break.

Honestly, if you can take a time-honored pile of crap and make it suitable for a sports car then you deserve some praise. I think they did a splendid job.
