The G-spot

What's the date of the latest TSB?

[SVT666]

Those with AT shifting problems you may benefit from a flash upgrade. It's a common G37 complaint and discussions of the below TSB are very common on G37 boards. I did the earlier version of this and it solved the clunking problems but it made the up shifts gooey at anything less than WOT. I'm gonna try to get the latest version of this TSB done when my car is in this week. The dealio is you have to ask the dealer to check - their flash machine analyzes if your car qualifies (S/N of the ECU and whatnot), and make sure they check too (sometimes they apparently do not).

I had it done two years ago. It helped, but it still wasn't great.

What's the date of the latest TSB?

I dunno about dates - it's rev D. in the link I posted but when I had it done it was rev B. Could only be documentation rev though, not sure. Will have my dealer check.

Steering with Pilot Super Sports is fantastic. Make sure everything's inflated to spec.

Bad or underinflated tires makes the G steering very syrupy (esp. with 19s)

Pilot Super Sports! Must me nice

[Laconian]

They're a helllll of a lot better than the miserable OEM Potenzas.

[12,000 RPM]

Hmmmm.... they are a lot cheaper than I thought they would be. I thought they would be like $2000+ a set

Nope. I think I got mine for a little over a grand after a Michelin gift card. That's not a whole lot more than other performance tires.

Where did you buy them that they cost that much?  On Discount Tire Direct they are $156 per tire.

[Laconian]

What size wheels do you have? Mine are 19".

[SVT666]

Ahhhh.  Mine are 18".

[Laconian]

There is very little competition for 19" hi-po tires. Methinks the wheels be too heavy for actual sporting.

[GoCougs]

Seems to be a fair number of 19" performance wheels out there - Corvette, Mustang GT, S4/5, M3/4, Q50/60, C450 AMG/C63...

[MX793]

There's a decent selection of 19" hi-po tires.  I've already started looking for replacements for the OE Pirellis on my Mustang and there are about a dozen different options on Tire Rack in the same size.  There appears to be more options if I look at changing from staggered to a square setup (which the front rims are wide enough to support).

If you can find what you want on Discount Tire, shipping is free.

I've actually heard that Ford dealerships offer very competitive tire pricing.  When my dad last needed tires, he shopped around at Tire Rack and Discount Tire and the like and his Ford dealer matched or beat their prices.  I'll see if that's still the case when the time comes.

18 and 20 inch sizes have much better selection. 19s suck for that.

I was just tire shopping for 14s; $50 a tire!

[12,000 RPM]

DWS06 16s are still like $600 for my Civic from Tire Rack. Then I gotta get them installed. Def gonna shop around.

17s and 18s are normally preferred, 19s are riding the line between stiff sidewall and heavy wheel.

So I have a Q50S AWD loaner for a couple of days. This version does not have the steer-by-wire and has trail braking (called "trace mode"). The latter actually works quite well.

[Laconian]

Trail braking, waat

[Eye of the Tiger]

So this thing has automated oversteer into fast corners. Pretty sweet.

How the Q50 doth shine...

A3 is a good buy. When they give it that dash screen in the new A4/TT/R8 the A4 will be redundant.

And I will bet all of the disgust with the Q50 stems from its infotainment system. Most of these new luxury cars are unbuyable IMO.

[Laconian]

I think it's OK, the car just drives really badly. I can't overstate just how bad that videogame steering is.

[GoCougs]

Steer-by-wire is an option though. This last loaner thankfully did not have it (it is indeed awful).

I was able to turn off all three displays which helps.

The G is simply a better car. Not as refined or upscale, but better ergonomics, more interesting to drive, costs less. Sad really - the Q50 has been a disaster for Infiniti. MY2017 is supposed to get the 350hp+ V6TT and better AT, but that doesn't address the core problems of the car. 

[GoCougs]

So I got that the ECM/TCM reprogram ($225). Not a huge improvement but it is noticeable, but you're gonna have to be fairly in tune with the car.

When in D it does kick down quicker, and will give a slight throttle blip too. Manual shifts are a bit more responsive. What I was really hoping for was quicker more solid up shifts at part throttle but that does not seem to have been addressed. The G transmission is supposed to be "adaptive" and I've been doing a lot of freeway miles the last couple of days so perhaps that will change.

[GoCougs]

So after a bit of city driving I can confirm part throttle upshifts in D are sharpened noticeably. Definite recommend. I like the car that much better now - much more pleasurable to drive.

[CALL_911]

The dealer charged you $225 for a reprogram?

[SVT666]

It was $400 here.

Surprised to see the C class so high.
