!!!ECU Update For Throttle By Wire!!!

Or, the other option, is that it's just random as to who has this problem. I'll still keep an eye out on this, but doesn't look like I have it right now.

You are exactly right. Actually doing the update would be an unnecessary risk for you. I've read in here that some ppl have had more complications after the update. Consider yourself lucky they got your ECU right the first time.

I'm confused here. I don't see how they could get it right and then get it wrong again, ie. some 02s have no problem, yet they made some 03s with the problem again. That just doesn't make sense to me. I'm also slightly confused about the symptoms as it has been described in a couple of different ways. When I think hesitation, I think lag, which I do get in the summer time and is basically just the car doing nothing for a second after I hit the throttle before it gets on it. Apparently, some say this is not the hesitation issue. I guess the best way to describe my issue is its almost like an automatic making a downshift and then it goes on its merry way. BTW, this is someone else's analogy, not mine. In any case, from those who have had the problem as I have described it, does the TSB fix the issue? Its so very hard to get a concensus on this issue.

Remember, this TSB does NOTHING for "throttle response" or "quickness", etc. and I don't think I got any horsepower change. Lots of people have mentioned getting some extra horses out of this, etc. but I took the car all the way to redline both this morning before the fix and after I picked it up, and I don't notice any extra power, no change at all there. Only change I feel is a smoother throttle tip-in, especially at low rpm. I am very happy with the fix!
BTW if anyone is interested, here is how my experience with the Carmax dealer in Greenville (I only have 3k miles so I have no mods yet)
Called service manager & discussed the TSB, he stated they would have to re-create the problem. Set up appt, and brought it in, they again were atamant about needing to re-create the problem. I gave them a copy of the TSB and a typed document I wrote telling them specifically how to re-create the problem. They cooperated and had the ECU re-programmed within a couple of hours.

Apparently, throttle lag is yet to be resolved. However, I haven't felt that issue either, unless I'm in too high of a gear, in which case the lag is natural!

Ive noticed that in my automatic! Its not like 90 degrees here but its been in the 60s recently in the north east and its been worse since its been real cold out.

They called Nissan technical help for assistance only to be told the update is BOGUS?!? Nissan is claiming they did not put out the TSB, nor does the NTSB have it posted on their website. Lawsuits are pending.
My service guy then stated they ran the update again and the computer took it. Some time maybe required for the computer to "relearn" itself and if my problems continue today, a new computer may be required.
If you have downloaded the TSB from page 5 of this post, hang on to it, you may need it in the future. Caveat Emptor!

Hi all..
Why don't you just put a link to this "How To on Recreating the problem" so you don't have to keep emailing org members..
Just a thought..

PS. If you have no where to put it, email it to me and i'll put it on a file server...

Has anyone noticed that for the auto and manual "if you confirm" parts, the manual says hesitiation between 2k-3k something like that and for the auto it says slight lack of power during acceleration.
Just kinda interested me when the "if you confirm" parts were different, anyone go about "How to" recreate the problem in an auto

How to re-create hesitation - 6 Spd Manual

Massvmax, I just emailed you the doc. Also anyone needing help re-creating should check out 10e's post on page 18. Below is the text I gave to my dealer in case someone is in a hurry; just copy & paste into word or whatever and print it:
Nissan Tech,
Hesitation problem:
You should be able to notice this problem with routine driving, but the problem is intermittent, so here is the easiest way to re-create the symptom:
After thorough engine warm-up under routine driving conditions:
On an empty street, drive the car in 3rd gear between 2k-3k RPM. Cruise at a steady speed for several seconds, then ease down smoothly on the gas; go from no load on the engine to about ¾ throttle fairly quickly but smoothly. You will notice the hesitation about one in every 3 times you do this. It is like a “hiccup”, in other words, the engine cuts out for a split second and then picks up like normal. Do not attempt to repeat this immediately by pumping the gas pedal, for some reason the hesitation does not happen as bad this way; instead, cruise at a steady speed several seconds before trying it again.
You can re-create this in any gear, but 3rd + is easier to really notice because 1st and 2nd are too low to discern the jumping of the drivetrain / etc from the engine cutout. You will also notice the hesitation in higher gears and at different RPMs. The hesitation only shows up when changing throttle position, from a cruising speed / no-load condition to an accelerating position. You will notice it most when trying to accelerate smoothly from a steady speed when keeping the car in the same gear. You will NOT notice it under quick acceleration or when changing gears.

oh alrite cool, I just saw someone say 1/2 hour than an hour for something else, not like it matters I will stick around and look at the new 04's and what not. I can already tell I dont like the gauges on them, the circle crap. Thanks again forthe doc too, later boys

Well, I talked to my service advisor and asked him if he would just charge me 1/2 hour for the reprogramming instead of me having to put the OEM intake on and then removing it and putting the FrankenCar back on. He said to bring it in on friday and he will do it.
My question is, how will I know that it's done and not just in my head?

Dealer Recommendation to Perform TSB?
As the subject line describes, I am looking for a recommendation for a dealership in or near NYC that already has performed, with success, the Drive By Wire TSB for one of you. Thanks in advance!

Ok, heres my post:
Took my 2k2 in for the wind deflector and hesitation problem this morning. When I picked it up the service manager told me the reason for the hesitation is because I have a K&N filter in my car(I have an amsoil panel filter in right now). According to him and the tech the filter is not seating properly and it is allowing debris into my MAF and that they have to replace the MAF. He then tells me that because of the filter it shouldnt be covered under warranty but they will do it this one time. After that he says that when I bring it back in I need to have a Nissan air filter in place and that is the only kind of filter I can run under warranty. I wanted to tell him to stick it up his a$$ because hes full of it. He knows he cant tell me that so thats why they are replacing it. I didnt want to argue because of that. Oh well, once I get it replaced I will put my Franken on and be done with it. Just thought I would share the crap they pull.

Well, my 2K3 is at the dealership right now. I dropped it off last night not knowing for sure if they were going to actually perform the update. However, I was quite impressed this morning on my way into work. The head mechanic at the dealer called me up and wanted to chat about the work he was going to perform. Basically just politely asking for my input on how the car hesitates etc... We will see what happens. I will post results tomorrow.

Nissan's U.S.A. Nissan-techinfo.com site has all this stuff as plain as day! I downloaded the farking ECU update from the site with a registration account! I have this sitting on my laptop as a .DAT file.
This is bogus, and whoever told you this should be the one being served notice!
Please note!
This is only if you are having this problem. It says it right on the TSB.
Sorry for the emphatic response guys, but it's the same thing in computers. If you don't NEED a BIOS update don't do it, because it will only give you aches and pains in the end...

I know I update most of the time whether or not its supposed to fix an issue I have, just my personality always wanting the latest I guess.
okay, i just got back from Montgomeryville Nissan and they tested my vehicle and said that my maf is bad. first question he asked me was whether i had an aftermarket intake on my car, i never had any intake. I asked if they were replacing the maf meter and he said no . he said that the maf was faulty and that the ecu would not be reprogrammed. I am very confused now. they are going ot call me when the new maf arrives and then i guess i will know if that can allow me to put on an aftermarket intake.i was hoping that they would change the meter and reprogram the ecu but it look like that may not happen.i just hope they dont try and put on a 02 maf again. that would defeat the whole purpose of this.

Again, in my experience, updates usually clear up some aliments that user/consumers don't really see/feel. Any there are plenty of examples, ie. a simple tweak in the way chipset communicates with main memory can improve performance and resolve software bugs.
Car, IMHO, are the same, and for that matter much anything that is software controlled...EVEN mobile phones!!!...
Back to the point, most updates ARE beneficial, this doesn't mean that one should get ALL updates that come out, especially in this particular instance (ECU). As I said before, the "improvement" in performance the some are seeing, maybe in fact just an update to bring the car up to specs...
Has anyone who has had the ECU update FOR the hiccup driven a non-hiccuping Max???...or vice-versa???...

I got my reprogram done on Wednesday. I have an early build 2k2 Maxima, and the service department ordered me a new MAF.
Although it does feel a little more responsive than before, I don't particularly think it's that noticeable a difference. However, keep in mind that I didn't feel I had a problem to begin with. I have experienced the hesitation as described on some posts here, but that was prior to the car break-in period. Since 10k miles, I've had no symptoms.
I also requested that the service department advance my timing to 17 deg BTDC. Service claims they did this, but I am suspect as they did not charge me for it, and there is no mention of it in the service order they gave me. I think I got yes'ed to death on this one. My "butt dyno" can't tell the difference, is there any way (other than going to another dealer) to verify whether or not the advance was performed?
