While it seems with minimal tuning, most of the MS's functions (MS-II in my case) can be made as good as or better than stock.... When I'm returning to idle it's not the snappy fall I'm used to, nor the quick stable recovery it could be. Some of that is the maps near idle, I imagine, and some the PID settings in the idle valve. I'm curious what you guys do, did you learn any tricks, etc?

I'd love to know how to get the revs to drop like a stone with zero throttle myself

Wouldnt there be a 2 second lag before the revs drop like a stone because thats how long it takes the injectors to shut off during over run?

Overrun? I'm not sure what overrun is, but basically, I'm just talking a run of the mill shift, in traffic or where ever, where you lift off the gas, press the clutch, and would like the RPMs to drop to idle without floating.

How long do the RPM's float?

I wouldn't say they "float" so much as return to idle slowly. Picture a stock car, and instead of lifting off the gas, you slowly over 5 seconds back your foot off the gas. That's what it's like. It doesn't wait-wait-wait-wait-DROP. It's backoff-backoff-backoff......

If it does drop, it overshoots, then hunts for idle for a while. I just posted a log in my other thread: "99-00 MS-IIx Initial tuning issues, Logs..." I guess you could look and see what I mean in there, there's a good stop maybe 1 min before the end at a stop light, and you can see it hunt.

injector opening time on a high impedance injector is 1millisecond I seriously doubt they take 2 seconds to close.

on a stock OEM car the initial lag is for emissions.
