How's the Drive-By-Wire (DBW) throttle?

Vegitto-kun · 08-14-2010, 03:29 AM

I have done that plenty of times when mates ask me and I don't notice any lag.

+ reving in neutral doesn't matter anyway, what matter is while driving/

I dissagree. It's probably not that big a deal in the autos, but it is much more pronounced in the manual. For instance, it makes starting from a stop more difficult and also makes heal toe more difficult as well (for those that turn off SRM). The biggest thing is that it takes away from the "feel' of the car. I like a car that has instant response to my inputs. For the most part while driving it is responsive, but i have had some instances where there is a massive delay in respone (like the car got confused).

If you have driven other cars with more responsive throttle response then you will know what I'm talking about.

Another reason why AT > MT?

The biggest reason why there is such a delay is probably emissions in some way.

But my car was a demo car that the owner of the dealership drove most of the time and he is a car nut who loves upgrading and tuning cars so I wouldn't be suprised if he fiddled with the throttle response

I turn off the DBW first thing after I get in the car, along with the VDC.

i would love for your explanation on how to do this.

IMHO where you notice it the most is when the car is cold... You know, you start it... it idles a little fast cause its cold... so you rev just a little - but once you let off it doesn't return to idle like it would if it were mechanically linked. This sensation is not as noticeable once the vehicle is warmed up.

I don't think the issues everyone is experiencing is specific to DBW responsiveness.. I remember, so does my friend, that the 350z had a "protection" where WOT isn't available till an RPM is met. Because of this you'll feel an unresponsiveness when you hammer the pedal to the floor... Almost like a turbo is spooling super slowly.

Get a tune to get rid of that.

I do agree though that I think this "protection" causes 0-GO a bit more annoying and especially uphill.

Doesn't it stop at 4K rpm's when reving in neutral ?

KusoSama · 08-22-2010, 10:28 PM

Yeah there is something wrong with the car but it's nothing a good tune wouldn't fix.

I'll patiently wait... Well... I'll try to.
