All i had to do on my Dodge Ram 1500 HEMI, was to disconnect the Neg. Terminal on my battery for a bit.. And you can spped the process, by turning your ignition key while its un-hooked. This will help drain it..
From what i understand, that when you reset the ECU you erase you drive habits that the car learns. This helps optimize max performance, or so they say. When i reset the one on my Ram, it increased my HP and MPG, and worked well with after market parts. The computers are designed to reset back to Stock Performance, even after you add aftermarket parts on it. Thats the reason to buy a TUNER, or Chip to keep what you set it to. This worked for my Ram, and i had to do it 2-3 times a month to get it to work correctly.. It does work. As for the Maxima, i think i read somewhere on here that it basically does the same thing.. It's a Learning/Smart Chip in your ECU that needs to be reset/drained..etc..
Hope you understnd my meaning.. guys??

You should also read the STICKY "Problems with 6th gen..." along with the other ones.

guys, flashing our ECU's is possible just by the pedal/timing method? we dont need an Apexi etc etc..right? cause when i installed a new K&N filter...even such a small mod, throttle response felt crazy...but only for like 2 days. so im hopin that method works.. are those the directions uptop? thanks.

I wouldn't call that method a 'flash' or a substistute for a piggyback by any means. It does just what it's called, 'resetting' the ECU.

my SES light came on again, for the umpteenth time, while under warranty, dealer dealt with it, now out of warranty and on again, tried the "A33B" multiple times, never even gets the SES light to flash...some secret I am missing??? Takes something special to see the error codes? I had a mechanic with some type of analyzer that checked it and then cleared it for me twice. Something available to public. I do own the FSM, but, cannot find a reference to resetting the ecu anywhere...

Not to beat a dead horse but I've done the "idle air volume learning" procedure for my vehicle about 87459087435480 times now with a stop watch. I've also tried the 987590438 variations of the "idle air volume learning" procedures provided on other nissan related sites. Sometimes the SES light is gone after ignition and sometimes it's not. One thing that it does have in continuous fashion is a severly rough idle and the SES light comes on while driving. It will blink really fast on and off and then stay on after awhile. I just had my spacers installed and I'm wondering if I can just pull my neg cable and let the car sit over night and see if that will work. Maybe I just don't have the timing right for the procedure. Any help will be appreciated. Kevin

They all seems related to not doing the learning process correctly. I called the stealership and they said they would do an alignment (ecf programming) for 108 bucks. Thought it was a fair price to get my car back on the rode. It's been suspected that my tech touched the throttle body plate. I was told that throws the whole system out of whack and would definitely require an alignment. Nissan confirmed the suspected mistake. If any of you pro's were a beginner enthusiast like me, would you resort to letting the dealership do this to ease the stress?
Any advice on this will be great.
Thanks Again

PS As of next week I'll be setting up my annual contribution and will no longer be hijacking and, in some cases, killing threads.

ECU Resetting Procedures
Timing is extremely critical. If it is NOT DONE within the specify time, the ECU will not reset and the Check Engine Light (CEL) will continue to remain ON.
A stop watch or an analog clock with a seconds needle will be useful.
Operations Procedures
1. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
2. Repeat the following steps (2a and 2b) procedures quickly five times within 5 seconds.
2a. Fully depress the accelerator pedal (HARD).
2b. Fully release the accelerator pedal.
3. Wait 7 seconds, fully depress the accelerator pedal and keep it for approx. 10 seconds until the CEL starts blinking.
4. Fully release the accelerator pedal (while the CEL is still blinking)
5. Wait about 10 second.
6. Fully depress the accelerator pedal and keep it for more than 10 seconds.
7. Fully release the accelerator pedal (The CEL light will continue to blink).
8. Turn ignition switch to OFF position and now you can start the car. The CEL light should be gone.
If the CEL light continues to remain ON, repeat the above steps. Timing is EXTREMELY critical to resetting the ECU.

This method does not seem to be working for my 2001 maxima GLE.
I tried resetting the ecu like a million times with a stop watch and everything what do I do?
Plus when i checked under the dash for the ecu - (next to the gas pedal), to do the screw driver trick, there was no screw its all flat on the side of the ecu. Is this normal? on the passenger side i took the panel off and there is a strip that i was able to take off and tried to start the car but it wouldnt and i could not see the ses sign in the dash itself. So i reconnected it and the car started but the light is still on.
Should i try the battery trick?

Yes, the method works flawlessly. It may take a few times because the timing in the process is so crucial. As for the injectors, this will have no bearing on the vehicle since it is not "ON". It can't be compared to what could happen with a carbeurator for example.
