You're correct that a heavy flywheel has more inertia, but this is more than that. The revs stay at the same point or even increase slightly for a second, then drop off normally. It's due to the ECU holding the throttle open momentarily. Years ago, this used to be done with a dashpot that was readily disabled. It's a whole different ballgame when the control electronics are the issue.O_GT said:what your talking about is how the the rpms kind of hang when you shift.That has to do with the weight of the flywheel.If you get a light weight it wont do that
This is just like the valve in the clutch master cylinder; it's designed to help people who don't drive a manual transmission well. For experienced enthusiasts, it's intrusive and counterproductive. It would be nice if Hyundai would offer some alternative ECU programs to allow drivers to custom tune this setting to their personal preference.skycam said:the ecu hangs the throttle during shifts but also if you just get off the gas abrutly. Hyundai does this to reduce the rubberband effect in the transmission, and to keep the tranny gears on the load side and not the idle side of the gears. Have you not noticed that there isn't a lot of engine braking when you let up on the gas, thats solely because of the ecm keeping the thottle open. Also helps with engine and tranny smothness. my .02
How do you do this? is there a DIY on it?2004ElantraGLS said:I did the Slave Cylinder Mod. The only thing it does is increase the amount of clutch fluid flow. In other words, it makes your clutch grab better/harder/faster. Don't get me wrong, it's not even close to having a Stage 3 Clutch, but it does get rid of the feeling like your clutch is slipping.
