Performance after transmission software update
Hey Forum!
I know this topic has been discussed, but I just wanted to confirm that those people who had their transmission software updated feel that their car is not as lively as it used to be.
I have a feeling that my car is now a duller and more subdued. Is this a common behavior after the transmission update?

Based on the 35 page thread, (which I skimmed through), it seems it's the other way around for most people.
I was actually looking forward to doing the reflash on Saturday, but "duller and more subdued" is not what I'm looking for.
I know this topic has been discussed to death, but that 35 page, 500+ post thread is a killer.
Only the people that had this done, please chime in

For me, it does mellow out the tranny a little, thus making the shifting a little smoother. This is the complaint so the fix usually results in a compromise in something. In this case, the car is a bit less aggressive. It's not to say that the car is any slower, just feels more tamed because of the more mellow tranny.

I also noticed that it holds the gears more, even when you press 2/3rd's of the way down on the gas pedal.
Also, I wanted to ask: Sometimes, i'll go from driving very tamely to needing to pass someone, so i'll put the pedal to the metal and the car would take off, then I would let go of the gas entirely and the RPM's would stick at something like 4k to 5k for about 2-3 seconds, sometimes 5 seconds. Why does this happen? Is it holding a lower gear just in case there is the need to do another passing maneuver?

This was an update I wrote in the other thread. To me the car feels the same, just less clumsy (especially in traffic and hilly roads). Since the engine braking has been reduced the car "feels" less aggressive, but if you want it to move it will.
"The car drives smooth and accelerates hard when called upon. Only complaint is the jerky downshifts below 35 mph (especially in stop and go traffic). But thats just the nature of the beast I guess. I mean there are 3-4 shifts before 35, so the trans is doing a lot of work. I still experience the lag, but only when steping on the throttle hard after coasting. If I slowly get on the gas there is less of a lag. Then again I know a lot of you don't want to get on the gas slowly and want to make use of the power under the hood, so step on it. Do it once and you might get a lag, but do it again and the engine and trans will be ready. I've done this many times and its a thrill when engine/trans rev match and choose the right gear. This all can be done in D mode. The DS mode is of course more aggressive. This trans is a compromise of a fast shifting sports car and smooth shifting luxury car while still being fuel efficient. It's trying to do it all, which is hard to do."

After my transmission update, my driving got smoother but when i press down the gas pedal to push more power it is more responsive. Considering my original complain was when i press on the gas pedal the car "lags" before putting out power.
So overall, on regular day/street driving, the car is more smooth and the engine is more mellow. But when you gun it it's more responsive.

I feel a slight improvement. The 40 MPH lag is still there, but reduced maybe 30-40%. After the reflash I initially noticed it selecting higher gearing when coasting, but it seems to have relearned its old ways and reverted back to lower gear selections at coast. Since my wife babies it and uses it as a daily driver to work on lower mph city streets, I sense it might also get a little confused when I get behind the wheel and drive aggressively. Overall I feel the reflash was positive.

nope, not regretting at all
only thing thats negative about it would be my local driving mpg went down but my high way driving mpg went up so it balanced out i would say.

^^ It would make sense that the city MPG would go down since the car stays in lower gear longer. Someone posted in the other thread that the MPG went up, which surprised me and also made me happy since I'm at 10 MPG city in NYC.
Is it much worse in the city after the reflash?

Shifts are smoother for me... and less frequent (significantly) in stop-and-go traffic. I ran just the TSB update for a few days while I waited for Hypertech to send me an updated calibration. I'm happy with the TSB update. It's not perfect, but they are definitely on the right track.
