Hi, forgive me this has been covered before, I'm a newbie here. Just picked up our 04 MCS on Monday, and I immediately noticed that the engine revs do not drop as soon as I lift my foot off the gas pedal. The revs stay up for a second or two before dropping. Is this an inherent "feature"of drive-by-wire, or is it something I can have adjusted out via programming by the dealer? It makes it sound as if I don't know how to drive a stick, and I've never been without at least one manual tranny car in the household in almost 40 years.

 

First off, Welcome to NAM! :smile:

This is a "feature" of the throttle-by-wire. The briefly maintained RPM helps reduce emissions and smooth shifting. It is also noticable when during idle, you mash the gas, there will be a few milliseconds delay as the engine prepars to ramp up the rev's, reducing emissions as much as possible. This technology implimentation is not new, and has been around for many years. This is not adjustable by the dealer, and currently only the Webb/Powerchips and reportedly the AmD OneClik have optimized the throttle response map to make engine response "quicker" at the expense of emissions.

I hope that helps,
Ryan

 

I noticed the same throttle delays on my MCS test drives. When I finally get my MCS, I will be interested in seeing how long it takes me to relearn my throttle & clutch timing so rpms are correct at moment the clutch is let out for a given gear and road speed.

I am used to doing minor throttle adjustments to help steer the car, particularly on snow. Has anyone found the delay problematic in adverse driving conditions such as snow or ice?

 

Thanks for the info. Glad to know about it rather than complaining to the dealer. My wife hasn't even noticed it, and I'm sure I'll be able to adjust. Of course, I may never get my wife out from behind the steering wheel anyway.

i noticed run on a lot when i got my 03 MCS but after a year of driving i don't notice it at all. V 36 software eliminated stumble, but now have deceleration stumble at 1900 rpm thats annoying.
