engine braking effect
+1 on the front motor mount. Either get a front motor mount or an ingalls stiffy and set it high. That will stop the jerking motion. All this talk about BOVs and timing and such is stuff to try if the mount/damper doesn't work. Also remember, its a transverse mounted engine; theres gonna be some rocking at low RPMs.

I've got the HKS SSQV. And I know exactly what you're talking about there. That's when boosting and trying to modulate throttle at higher rpms, though. This happens to me when just cruising, and releasing the gas at a fairly slow speed. I hope it's not the clutch, because I'm already on my 2nd twin disc with one rebuild in there since the February prior to last. (Long and painful story.) And I only have about 2k miles on this clutch, with extremely proper break in.
I've been told that it's just the nature of the lightweight flywheel, which I tend to believe. It's something I can live with. I just hope all the clutching I do doesn't wear out my TOB too quickly. Well, you gotta pay to play.

You did replace the TOB when you switched out the clutch?
It's called coasting fuel cut by DSMlinkers. DSMlink gives you the ability to push the RPM up as high as you want, or effectively disable it. IIRC, AEM calls it DFCO (Decel Fuel Cut On) and you can set it up however you want. It's strictly an emissions thing, no need to be burning fuel when you're coasting. The ECU looks for RPM over the set value, plus idle switch or throttle closed switch made, and it cuts fuel.
here you go...

If its just compression braking, is it possible to max out the MIVEC table in the low load, moderate rpm cells so that there is as much blow through as possible? Probably would make only a small difference I guess.
Drivetrain slop?
When I let off the gas in the conditions you stated, my car jerks back and forth quite annoyingly.
Tephra, can you release a patch to get rid of drivetrain slop? he he...

I honestly find it difficult to get the injectors to shut off. When letting off, and going down hill my AFR are still around 14, I blip the throttle and THEN it realizes and the AFR goes up to 20 (leanest the WB can read). Maybe that helps you find it? For me it only engages after an abrupt throttle change.
