Okay...I know everybody loves the ECU reflash to get rid of the touchy throttle, so I jumped on board and did it. Mind you, I didn't feel a lot of it to start with, but thought I just had got used to it and if it was drastically that different then it could only be better. So I get it done, and my thoughts after the first week was that I really didn't notice any difference.

HOWEVER...I'm two weeks after having it done...and now the jerkiness actually feels worse? It now feels like how everbody was describing, very jumpy taking off, to the point that you would spill someones drink in the passenger seat. Much more than I had ever felt before getting it done. How can this possibly happen?

I'm hoping that its just that the throttle responsiveness was unchanged, and now I'm just paying much more attention to it because of the reflash and just realizing how touchy it has always been.

Is there any other possibility that could have happened? Has anybody else had anything like this happen with their reflash?

hmm, Did the service writer give you your paperwork? It says if the Tech Drove it and Experienced the CC Surge Issue, and your ECU had the #'s that said it was part of the Reflash update? If Not then they never did it, since on my papers it descibes what the tech felt,m and listed they performed the reflash per the Instructions!? Or It could be you were used to the Touchy Throttle, and now that it is less sensitive since the Reflash, you have to relearn the lauch?? I dunno.....for me I get a little jerky take off at first since the reflash, but now I got used to the Less touchy throttle, I launch more smoothly then before with less Throttle Input. Guess everyone drives diffrent. But I report the reflash to be positive Even when just driving without CC, like going down a hill and you let off the Gas to coast, before it would feel like the car hits the brakes a little kind of sensation, now with the reflash you can barely feel this now, and it does it alot smoother. Just my 2cents. Hope you get a better feeling for the new Reflash. By the way when was your car built? It was onlt for Early Builds ths reflash was for?

I didn't notice significant tip-in imrovement at all, but my CC is SOOOO much better now. If your CC is better than they did perform the TSB correctly, if you don't notice any CC improvement they may not have reflashed it per the TSB.

I've just gotten used to the touchy tip-in and don't mind it now

I have an 08 and IMO, the throttle was every bit as touchy as the three 2007 Gs I test drove - and I test drove the 07s for long periods.

After 2K miles, I'm used to the throttle now.

TheIvoryG - I'll bet if you just drive and don't think about it, it'll feel fine in a couple hundred miles.

This discussion of the ECU and throttle issues reminds me of the problems I had with my Lexus ES330 (which I dumped for my G). The difference is that the ES (and Camry and other Lexus/Toyota vehicles) had a throttle lag, so the car would respond too slowly to pressing the accelerator (the opposite of the G problem).

There was a lot of discussion about this, but one particularly interested me.

The poster, an engineer, explained that in cars with an ECU, the driver's foot pressure and position on the accelerator is "read" by the ECU to determine the intent of the driver. Simple enough, but the interesting thing is that the pressure and position can change depending on the seating position of the driver. In other words, the vehicle's acceleration and "touchiness" was largely the result of how the driver pressed the accelerator.

I'm certain that the Infiniti implementation of the accelerator pedal is similar to Lexus. That would explain why some drivers find the car too "touchy" while others don't have a problem. Also, if you change your seat position, the feel of the throttle would "feel" different, because you are pressing the accelerator differently.

I'm no mechanic or engineer, but this explanation made sense to me.

G354jb has it precisely right. Seat position made all the difference for me. Moreover, because the accelerator pedal on the 07G35 is hinged at the top, not the bottom as are most pedals, foot pressure is even more significant. I found, just as you point out, that moving the seat back and down allows the foot to get higher on the pedal, thus reducing the lag and jerk you'd feel if you push at the bottom of the pedal.

Having a Sport 6MT with its long clutch and high engagement point also necessiated moving the seat back and down.

Once I found the right seat position, shifting and accelerating both went much more smoothly.
