Ahh, I re-read that too. It looks like the sensor replacement may be optional on the 6MT, but the flash isn't.

 

No idea what the problem might be then. My experience is pretty clearly VDC.

 

Despite my dealers initial reluctance to admit anything was wrong, they just called and said they fixed everything except the high cold idle, saying that 2500 RPM cold starts are within operating range. I did have to verbally give them the ITBs for the bluetooth and the cruise control which they applied both. That said, it looks like I got the 028a flash and not the 045. Based on my research the 028a seems like it has a positive response. I'll be posting my feedback later.

They did replace ALL my weatherstrips which I'm really glad since i had some crazy wind noise problems. After having my loaner car 06 G35, I realized how bad my wind noise was. PS - I can't wait to drop off the 06, it's just way less cool. Its exhaust drone gets annoying quick as well.

 

Well windnoise is WAY down and the new clutch feel is totally different, I think better. It seems softer at first but as you drive more it seems to remain consistent. The new 028a ECU flash seems less herky-jerky although there's still "some" throttle lag. The verdict is still out on whether it feels slower. Coming out of an 06 auto loaner it's hard to tell since loaners always feel torquier.

 

An update to my original post.

I brought my car in this morning for service and just received a call from that that they have performed the clutch recall as well as the 028a upgrade. They did not apply the 045 flash as they could not reproduce the problem. I asked that they keep the car over night to test it in the morning as that's a more accurate picture of reproducing the problem as the car had been driven for a good 25 minutes by the time I got to my dealer.

I will post the results when I get my car back tomorrow.

 

The new clutch cylinder is awesome. The clutch is way more consistent and it doesn't chatter anymore. 028a also seems to be an improvement. It doesn't buck when I jab the gas.

Let me know your thoughts.

 

Have had the car back for a few hours now and I'm very happy thus far with the results. I'm especially pleased with my dealer (Frontier Infiniti in San Jose, CA) as although they weren't able to reproduce the issues for 028a and 045 they still applied the updates noting on my work performed sheet as "installed as per customer request and as a precautionary measure." Their service department is great over there.

I agree, the new clutch cylinder is amazing. The car drives like I always felt it should drive. The three updates addressed all my issues with touchy throttle, cold engine issues, VDC being a pain the ***, jerkiness at low gears/speed/rpms, etc.

The first 20 minutes or so of driving I definitely felt it doesn't buck as much when you punch it. However after an hour or so I got used to it and felt it was just as responsive as before. Prior to the updates, the quick acceleration always felt just a tad awkward but now it feels much more smooth. It may not feel as responsive jabbing the gas in 1st or 2nd at first, but when going through the gears it felt much much better. I'm not fighting VDC and seemingly it accelerates much faster/smother (I used to consistently drive with it off because it would **** me off).

Another thing people mentioned was that hitting 5th and 6th gear seemed to be more of a task after the updates. I definitely noticed the difference, but it's nothing drastic. When I first put it in 5th I felt weird about it because it seemed like I didn't have to go as far up and to the right to engage it into 5th gear. The shift from 4th to 5th feels shorter, as does 5th->6th.

I'm sure I'll have some more updates after driving it for a week or so. But for now, I am pleased, and I'm going to drive the **** out of this thing because it feels like its brand new!

 

Yup I agree on the New Clutch Cylinder Update! it's way more Consistent, no Light Pedal feel that comes and Goes! And the Pick-up point is perfect for me Now, Right in the Middle!! I am very happy now. Never got that Bucking thing you guy's mentioned under Full Throttle? And shifting through all 6 gerars is Buttery smooth! My G feels better than before!

 

I didn't have a bucking while in the throttle, I had this LAG if I went from minimal throttle to deep throttle (like passing someone, etc.). It was annoying. It's much better now. You can still tell the car is drive by wire but it's reasonably responsive now; before it was embarrassing.

 

Anyone have any feedback on just the clutch slave cylinder recall (no ECU reflash)?

 

Hey mishmosh,

I just got the clutch cylinder done and the order sheet didn't say anything about a ECU flash.

See my comments about the clutch on the sticky thread above, otherwise, let me know if you have any questions.

 

You can separate my comments. The clutch alone is worthwhile. It's more consistent, the engagement point is better, etc.
