2009 and newer ISx50 paddle shifters shift quicker than 06-08

When I say more responsive I mean that when I lower the top gear (i.e. "downshift"), the car "shifts" into that lower gear with less of a delay. Assuming my perception is reality, that would most likely be a difference in the ECUs, not the trasmission, right? We do know for a fact that the ECUs are different (the '09+ ISx50 allowing use of the paddles with in drive), so to me this theory is entirely possible. I've also driven '06-'08 IS250s on several occasions, and the paddles have the same lengthly delay as my '06 IS350. Again, it's all anectodal... Where's lobuxracer?

The reason has been provided several times so far in this thread: because they aren't actually paddle shifters, but merely gear limiters. The only scenario I could envision them being useful would be on a freeway race when you want to force your car into a lower gear before gunning in (to save time on downshifting).

To add to brociouz comment, you still don't have full control of the shift. When you downshift with the paddle shifter, you are only locking out the gear and forcing the ECU to use the lower range of gear. The ECU still decides what gear to use between the range of gears left.
That is why the paddle shifters on the ISx50 are utterly useless. The only application I see is for downshifting, or in other words, lock out the high gears.
I learned this from the school of Kurtz.
If anyone wants to compare apples to apples for the next CL Meet, we can compare pre 09 IS250 to mine with the paddle shifter. Perhaps, record the downshift with a camera.

If you're asking if the IS-F will prevent you from downshifting to a gear that would cause the RPMs to exceed the redline, then the answer is yes. The same applies to the ISx50 gear limiters. The car will emit an electronic beep to let you know "I'm not going to let you blow the engine up, stay in this gear for now."

The paddles are NOT worthless.
When cruising down long hills in vermont they come in nice and handy to throw it down a gear or two (from 6th) to hold your speed where you want it.

Like every other technology solutions, the end result is how one adapts with the technology at hand. A creative driver will combine the ECU's recommendations to upshift with his/her need to downshift on demand, within the constraints set by the system to not destroy itself ie. not let you Rev over redline nor let you shift into a higher gear that will stall.
