Default REPOST: (Gremlins!) -- RPMs hanging between shifts.

Do others consider this annoying? When upshifting, I let off the gas, put in the clutch, and the RPMs just sit there for a second. On the same note, if I accelerate to about 3500 RPM, and quickly take my foot off the gas, I don't feel any engine braking right away. It just sort of coasts for a second. I'm assuming these are interrelated. Checking the archives revealed something about a "dashpot?" but most info was inconclusive.<p>Is this for emissions purposes? I have heard this goes away after chipping. Have others found this to be true?<p>ChrisWB<br>99 1.8tqm <p>

If you really need falling revs, considered a lightened flywheel?

Seeing how the effect is decreased with &quot;chipped&quot; engines, I doubt it has anything to do with the flywheel.

<i>When upshifting, I let off the gas, put in the clutch, and the RPMs just sit there for a second.</i><p>Yup, sounds like mine prior to getting my Wett chip.The stock chip seems to be setup for "lazy" shifting whereas the Wett chip rewards a quicker shift.<p><i>On the same note, if I accelerate to about 3500 RPM, and quickly take my foot off the gas, I don't feel any engine braking right away.

The stock chip seems to coast as if it were equipped with an automatic transmission. I found this behavior annoying as I constantly had to tap my brakes to slow the car just a little bit. After installing the Wett chip, the engine braking is much more dramatic.<p>Andy Hedin<br>'97 A4 1.8Tqms, Wett 1.0 Bar, ABT Filter, Euro Headlights...<br>

Default Agree; this is a FI control effect

If I'm decelerating with foot off gas and push in clutch, engine speed drops reasonably. If doing a normal shift whre am on gas and lift to do shift, speed hangs up. Definitely in fuel/air control gizmos.<p>Now, looks like a chip helps the 4-bangers. How about the 30V V6?
