The NEO is still made as it is their newest product of it's type. The SAFC/VAFC are not available on their site, but I'm sure otehr vendors will have one in stick.
If not there's dozens more car forums that will have one, since it is not Maxima specific. There's always eBay. I bet you could find one used in the classifieds here on maxima.org.

If the dealer has to reflash your ECU to correct stalling or tranny shifting issues, etc then you will loose the TS flash. If you have a 2004 MAX, I would check the TSB's (nissanhelp.com) to be sure your model does not require any dealer reflash. Then, do the TS flash.

Just a thought...
Oh, my "Service Engine Soon" went off today. Also, I found a Shell station near me that sells 100 octane gasoline. Before I fix the A/F I'm going to fill up on $5 gas juz for fun.

Yeah If I can find one for cheaper I will but the thing is that if I get one from a junk yard I will have to get it cloned or drive with the ECU program that is in the one from the junkyard. RH chime in at anytime to elaborate.

............are you ****ting me? Why would there be issues with the transmission shifting wrong?.... What would it say on nissanhelp.com that would let me know if they have to reflash it or not? I'm going to 
myself if something gets screwed up here...

Ocassionally, there are warranty updates to the ECU programming. My wife's BMW gets a new program installed every time she even goes in for an oil change. That said, I know of no reason why Nissan would want to upate your ECU. However, I think our friend Madmik is correct in making sure that any of us who have paid $500 for the current program oun our ECU (from TS) never have it overrided by some dealer install to overcome some petty warranty issue. Best to ask, I guess, when doing any warranty service.

To program key to ECU, they only need to get to the key encryption chip, nothing else. And if for some reason the dealer reflash your ECU, you'd be out $150 for another reflash; $500 if you don't.

Just check the TSB for the '04's that require ECU flashing. If you need it, get it done first since TS will only adjust the timing, throttle, A/F, etc.

installed.........................bottom end seems same, haven't tried mid-top end much, but neutral I get to redline to 7100! 
The tech hooked me up and only charged $105 labor for the ECU install since I shortened his work by taking everything off so it'd be easier.
I was freaking out when he went on a test drive because he was gone forever and I thought the ECU was bad and something happened to the motor.... lol

lolMy car has actually been running better this week. Just took a trip to the store and let it loose in a tunnel. Sounded sweet with the CAI and Y-Pipe. I'm going to put some 100 octane in it tomorrow (half and half) and see what that does. Found a local Shell station that sells it at the pump. I also get my 07 spoiler put on tomorrow. I plan to drive the car a lot tomorrow, so it should be very informative. My tech will also check out the A/F situation for me.
Have FUN!!!

To be clear: The dealer most certainly CANNOT adjust the A/F. He CAN, however, tell me how lean I'm running, etc. I suspect that my ECU has done a bit of learning this past week. The "Service Engine Soon" light came on for a day and then went off, so something is going through it's mind ;-) He's just going to give me some insight as to what is going on.
I forget you're only 17 years old. If I were you're dad (my oldest son is 21, so I'm definitely old enough to be) I would let you get the NEO installed ;-) But, you'd have to mow the lawn all Summer long - just kidding.
ROCK ON, my young friend

I can sell you my stock ECU...make sure to find out what your #'s are though. If mine are different from yours, then no work!
My buddies dad owns his own shop and he managed to find a spare ECU for $350...oh well!

man this is so confuse can we get ECU reflash from TS with not problem at all or any one that have his ECU reflash will have some diferent problems????
Other question is HOW the APEXI NEO WORK ??? how you know if you getting more gas than air or more air than gas or whatever we need that APEXI?? do we need to run the dyno first to know what to do with apexi or it can read what we need to do someeeeeeeeee body explain meeeeeeeeeeeeeeeeeeeeee all thissssssssssssssssss pleaseeeeeeeeeeeeeeeeee pleaseeeeeeeeeeeeeeeeeeee very slow and clear jajamy english S**K

I wonder how many 6th gens had a reflashed?

Nice way to blow it up.

The wiring is the same across the board for any AFC, since they all are after the same signal.

I think this would be cool for a modded Max. Lots of adjustments and I love that bluetooth link to a PDA. I already sent an email to them asking them to make a plug and play for the Max. Maybe if a bunch of requests came in at once they would do it. They aready do the Z so it can't be that much more to do. I like the idea that the setting can be changed so when you do a mod you can continue to correct any fueling issues.

right now I kind of feel like one of those "I think I feel some more power" people. We can't really find out if TS did what they were supposed; only thing you could is the redline, and other stuff you would either have to go all out and go over the governor, or get a dyno to see your AFR.
Maybe I need to give the ECU to "adjust" to my driving habits for the next few days and then it'll learn and perform better. Low end, is still about the same and mid I can feel a little difference, but top end seems almost the same if not a little sluggish...maybe I have to be a
and test out the no governor?
Main fun thing is the 7100 redline. Holding the shifter down and then letting go so it could shift by itself...it takes a little practice so that you don't bounce the redline and bog the motor, but once you get it, 1-3 gear is
