Thumbs up Good News

Went to Infiniti of Manhasset in Long Island today to get serviced

Service guy said they are aware of the problem and every 07 will get a letter in the next 30 days and everyone will have to come in to get a reprogramming of ECU and ICC

Has anybody got there re-flash done any where near Sac CA or bay area. I am looking for a dealer that has more experience doing these. Talked with IvoryG which he got his done a Infiniti of Sac, he says he can't tell a difference. I am not sure about the guys at Sac Infiniti. These are the same guys that told me they had no way of telling me what the off-sets where for my G. I mean come on, I guess I should have asked the guys at the Honda dealership!(Sarcasm)

I had my g35x tech/nav done last week. I was supposedly the first person to have it done at Ray Catena in Bridgewater, NJ.

The car definitely drives differently now. Much smoother.

BUT - they botched the distance censor install, it was picking up cars in the right lane, but not right in front of me. The car would let me get about 20 feet behind the car in front of me before braking. If I was in the left lane with no one in front of me and came up on a car that was in the right lane, I'd either be good until about 40 feet and my car would slow as it ordinarily would for a car in the same lane as me, or worse, it would let me get to about 20 feet behind the car in the right lane and then SLAM on the brakes. Totally unusable.

I called the dealership and, get this, was told that this is how the car is supposed to operate since I was tested after the distance sensor replacement and ECM reprogram. When the service writer asked me if it only happened when my wipers were on, I knew I was in trouble. After some convincing, I got another appointment to have it fixed.

I was there today and watched them do it. Kinda neat actually -

They plugged in a bluetooth adapter to the computer connector under the steering wheel, that connected the car wirelessly to a Panasonic Toughbook running Consult III. Then the tech put this big cardboard pattern about 15 feet in front of the car and the computer did the rest.

All is working fine now - back to normal.

Moral of the story? If you have this done, make sure you test the car your self before going to far away from the dealer.....

OK, second dealership had a clue. Service was done and the car is much improved. I still have to grade the thottle response linearity well below my S2000, but that car is best I've ever sampled, and the G has a slushomatic trans.

The TSB service made the initial throttle response much more manageable and all but eliminated the little hesitation, any remaining hesitation is most likely due to the torque converter and is just the reality of not having the correct sporting (manual) transmission.

So, the car is much improved. anyone with an 07 G should get this done.

This is also why it is less apparent when you mash the throttle: the problem happens for a shorter time, and gets drowned by the fury.

Anyway, it is irritating, mainly because they can't fix it, and it is only a software patch.
It's not a bog (that implies power is lost), it's a lack of reaction. From what I can tell, you can push the throttle close to half an inch with no reaction from the engine - then once you get a reaction, it's the one you'd get if it actually followed a linear curve (in other words, you get the '1/2" throttle response' instead of the curve just starting late. So you get a bigger hit of throttle than expected.)

The problem is still there exactly the same when you mash the throttle, it's just that you wind up the throttle curve very quickly, so any perceived gap is minimized.

It was the same in my Max, so I'm used to it - would prefer not to have it, but not a big deal.

Bottom Line on flash to correct acceleration

So, first you need to understand. For 45 years I have driven nothing but sticks. I have never owned an automatic. Big standards, little standards, sport car standards, trucks, everything. I think that I am VERY good with a clutch---Until I got my '07 G35S. I drove it out of the lot and was back 20 minutes later complaining about the lag and then lurch in getting out of first. They said it was normal. I thought it was absoutely terrible. Came back to complain a couple of months later. Same thing.

So, yesterday I downloaded and brought over a copy of the TB07-028a correction and the '015 correction for the voice tags. The voicetags now work fine. The clutch is now UNREAL. This is the single best thing you can do with your car Completely, and I mean Totally erased the lag and lurch problem. It seems like a completely new car, could not be better. Perfect.

Try it. You will be amazed.

I'm having a trouble finding the TSB for the update. Could someone point me in the right direction or provide a link. I'm getting ready to purchase a pre-owned '07 and I want to make sure it has the new key FOB's and the computer update before I buy.

Thanks,
Chad

OK, i'm not too savy with car and engineering lingo so bare with me. I'll try to make some sense of some problems the ECM fix did. Some problems I noticed with the car was when you accelerate from a stop, the car has a tendency to leap forward. It basically goes from 0-20mph in 0.01 seconds. Another problem was say you are accelerating and then for a moment you take your foot off the accelerator, the car seems to lurch back as if its in between gears and cant decided which one to go to. This leaping forward and lurching back motion just after a while seemed normal for me and I had gotten used to it, that is until I got the ECM fix.

It is honestly a completely different car now. The acceleration is super smooth from a stand still. You can basically punch the accelerator and it refuses to leap forward as it did before, in fact, this might be psychological but it seems as if the smoothness has actually made it faster from a stand still. Also the lurching back motion when removing your foot from the accelerator is completely gone. The shifting of gears is almost non existent. Its like that Maxima commercial where the lady is putting on her makeup while the guy is revving the car. Can't even feel it. As others have done, I highly recommend this TSB. It brings new life into your car.

There is NO SEPARATE TSB for this fix. It comes with the "CRUISE CONTROL SURGES WHEN GOING DOWNHILL" TSB aka "ITB07-028a". I had to basically lie to them that I had the cruise control problem to get it done. Luckily the service consultant did ask me any further questions about it. They do a variety of things with the ICC sensor to fix the cruise control "problem" but most importantly they reprogram the ECM which fixes all the above problems mentioned.

You can download the TSB .pdf file from here after you register with the website: http://x.infinitihelp.com/forum/loca...s.php?catid=77

Can anyone who has had the reflash done with the ECU and the CC PM me your vin. I have a dealer out in NY that is willing to do it but he needs a vin# so he can see what was done to your car.
THanks.

what do you guys mean exactly when you say the car "surges"? I'm in LA so it's difficult to test ICC cuz of all the traffic but I do have the issue with too much throttle from a stop. I'd like to get the ECM reprogrammed so i want to know what you mean by the car surging when going downhill using ICC. Thanks

are you guys using ICC or the "I" is off?

It just surges. Feels like the CC is playing with the gas, obviously on the gas, then purposefully off the gas, then on, then off.

Your cruise control should be smooth. Without the reflash it is not when going downhill.

I'm in Florida, I used a bridge and/or onramp to feel the surge.

I also don't have ICC.

I just gave my car for service. Hopefully they will take of this.

The loaner I got feels so much better than the other loaner I had driven. The throttle feel is excellent - it almost makes wish I had got an auto The last loaner would just surge when pressing the gas and was not fun to drive.
