I've been reading a lot about DBW(i think that's it) lag (throttle lag), and I'm curious, is this only with VDC on? I always drive with mine off, and i don't notice any lag (but then again I'm still breaking it on, so i really havn't gotten on it)

probably in an automatic tranny, I dont notice lag on my 6MT..

 

There is a slight lag when you heel toe

 

sorry, i'm new to manual, what's a heel toe?

 

retret, It's a finesse move whereby you heel the brake, and toe the gas to maintain revs while shifting down. Takes a lot of practice. [img]/w3timages/icons/smile.gif[/img]

You use it primarily while turning (or am I mistaken?) You can apply the brake with your heel, blip the rpms with your toe to match revs while you downshift and come out of the turn a gear lower.... or at least, that's my understanding, from what I've read =) Never actually done it!

Dang, I have a small feet, but anyway pls correct me if I'm wrong, when Im approaching a stop sign I clutch in then shift to neutral(not fully stop)then clutch out, after that I step on the clutch again and put it in 2nd..what am I doing wrong?

 

Sure. Sounds similar to what I said. [img]/w3timages/icons/smile.gif[/img]

If you're making a short stop, you can just hold the clutch in.... longer stops, you want to put it in neutral and release the clutch (to lengthen the life of your clutch)

I see, thx

 

You'll notice it when if you use engine braking to slow down while coming to a stop. It's not a big deal for me since most of the time I'm usually applying the brakes while down-shifting (when coming to a stop). But if you don't use the brakes and just down-shift to slow down, what you'll feel is the car continue its speed before actually slowing down. It's a similar feel to an automatic just coasting when you let go of the accelerator.

Actually, downshifting at every stop and turn is not recommended on most passenger cars today. Typically nowdays, its suggested use is for helping the brakes hold back the car when going down very steep hills. The logic is that brake pads (and rotors) are much cheaper to replace than clutches and transmissions. Plus, the engine braking creates additional wear on your rings and cylinders. I haven't read the G35 owners manual yet, so I'm not sure what they specifically suggest. Large trucks or auto racing, on the otherhand, is a different story.

There is virtually no wear to your clutch pads when the clutch is fully engaged on fully held in. The wear occurs primarily while the clutch is being released as the engine driveshaft and transmission have to adjust to the same speed. The main reason you would want to put the car in neutral during long stops is so that your foot doesn't get tired of holding the clutch to the floor.

I've heard that too and I understand the logic to it, but this is the way that I see it.

If you modulate your braking in your automatic (ie, press hard, release slightly, repeat), it also downshifts. If it doesn't, then there's a big lag before it downshifts when you hit the accelerator and you receive a nice jerk (when doing a rolling stop, for example).

When I downshift, I'm either at the right speed or below what I need to be before shifting, or I rpm-match before shifting. In either case, I'm braking while doing all this. I seldom just downshift and let the car slow down. For the times that I do downshift and slow down, however, is in preparation for acceleration.

I can't imagine that driving that way would be something that the tranny and clutch couldn't handle.
