I've seen it mentioned here and in MotorTrend, but has anyone actually had the "new" ECU programming for the 2008 sedan done on their 2007?

I'd be interested to hear results.

I'm less worried about how aggressive the throttle is, and more curious to see if it'll fix any other wierd quirks with the car (mostly tranny issues).

 

I just read that yesterday too! I haven't really had an issue with how the throttle responds. Maybe it's in the auto's.

 

What tranny issues? The AT tranny is as close to perfect as it gets.

 

I got the new program this week. I went to get the "cruise surges when going downhill" TSB fixed, and they reflashed the ECU. So far, I have noticed that the car is easier to drive sanely in town (throttle is a lot less touchy).

No report yet on fuel mileage change.

 

did you ask them to do this or did they do it as part of the TSB fix?

 

I asked for it. I brought the car in to get the new i-keys, and decided to have the cruse and htd. seats fixed while it was in.

 

Tiger:

Did you just ask for the TSB fix, or did you ask for the 2008 reflash as well? I sent Infiniti a question yesterday about this and received this very helpful reply ;-)

I just purchased a 2007 G35x. The throttle tip in is extremely abrupt. I noticed that the review in Popular Mechanics mentioned that the 2008 model had less abrupt tuning. As the engines and electronics are identical I would like to have my ECU/ECM reflashed to the 2008 settings. How can I go about having this done? Would ITB07-028 accomplish this? > I bought my vehicle at Infiniti of Ardmor</comments>

I wanna have this "reflash" done too.. but i guess i'll wait for a little while

 

The TSB fix for the cruise control is a reflash of the ECU. The air/fuel maps are all rewritten.

 

you still didn't answer the question. Just because the ECU was reflashed to fix a problem doesn't mean it was reflashed with the '08 ECU program. Did you ask for the '08 reflash, or did you just assume the TSB's fix was to the latest ECU (i.e. the '08 sedan). Because if that's the case, then I don't think you have the '08 program.

 

Does anyone have a reference for a 2007 being reprogrammed with 2008 SW? I have not been able to find anything in Motor Trend, only this article in Popular Mechanics:

http://www.popularmechanics.com/auto...s/4220194.html

"But it’s difficult to be smooth around town with the Infiniti. The engine’s throttle tip-in off idle is pretty abrupt. It’s not a problem on the open road, but in stop-and-go driving with just a touch of throttle, we’re spilling our morning Starbucks. Trying to grandma off the line just creates a lot of cutting-in-front and merciless honking. Sheesh.

So, we called Infiniti, which resulted in a senior powertrain engineer coming by to demonstrate a 2008-spec G35. The company had identified the same issue, and revised the engine-tuning param*eters appropriately. It’s a big improvement."

Note that the 2007 was not reprogrammed; rather a 2008 G35 was demonstrated.

 

I'll try to reword this as many different ways as I can...

I went in to get the TSB fix for the cruse control. I left with a car that is much easier to drive at a moderate pace.
I don't spill my Starbucks every time I leave from a stoplight anymore.
La válvula reguladora no está como rápidamente

 

Would this reprogram have any benefit for manual cars? It also seems an abrupt engaement. Thx all

 

Not trying to be a dick here, but you posted in a topic titled "08 ECU reprogram for 2007 cars" claiming you got a TSB fix and they reflashed the ECU and it appeared your throttle is smoother.

Whether or not you intended it, by doing so, it implied that you thought you got the 08 ECU given the topic heading.

So chances are you didn't get the 08 ECU update. Just trying to get a perfectly clear picture.

 

Thanks for the clarification dopey, I was also confused in thinking we were discussing a 2008 ECU reflash into the 07.

That being said, even if the 07 TSB does help the problem, those of us with the ICC are still left out?
