Thanks lot for a big head up !!!! BUT wait. Would my mods void the warranty? currently running aftermarket intake, cats and exhaust.....anyone?

 

I went in with an exhaust but cats are under the car too so I assume that won't affect it. But intake they can see so that might be a problem. Not too sure on that though :/

 

But how can you tell if they update to the latest? except that you can feel it lol. Does it say anything on the print out?

 

Tracked by VIN. They can also plug in the computer and see what current software is on the ECM & TCM. If it's not current & you're under warranty, they'll just update it (that's what my dealer told me).

 

Got mine done yesterday its like night and day....thanx OP

 

I got an appointment for tomorrow. Dealer said they gonna take a look at the car first so hopefully they will update it.

 

okay, got it done today and it said ITB12-027D applies. why is there D instead of C like everyone else?

 

I got the transmission update today on my G37X coupe, feels like a brand new car now, shifts are much smoother and the throttle lag is reduced!!!

 

Revisions to this TSB have been to include more models and years.

 

Would this work on my 2012? I just got it in January. Has anyone with mods gone to the dealer to have it done? Did they give you any problem? I have intakes and HFCs

 

Got mine done a couple of months ago...huge difference and definitely worth doing. The revision was up to '075C' when I did mine.

 

Wow what a difference in the reflash. My Ipl before was sluggishand always seemed to be hunting for a gear. All that has changed . Transmmision downshifts far better throttle lag is must less. Thanks folks for the suggestion here on the forum.

 

After reading all the Threds on the updates Motor, Trans etc I called up my Dealer and asked the Service to book me in...
He goes what for??
updates on the Gcoupe! He goes not that I'm aware of...I'm like Biach Please....check...he came back and said yeah there's 3up dates...when can I schedule you in...sir..
Lol lame ****! Thanks guys for the posts go in on Monday! Whoot whoot! Doughnuts and Coffee!
no wash though!!!

 

So if my G doesnt feel sluggish should i still bring it in

 

ok so this is completely ridiculous. I brought mine in and it is no different than before, in fact, maybe worse since it lost what it learned of my driving. I have no idea why people think anything has changed since they first produce the accel tables, etc. Its no different.
