Hey guys

I have beeen driving for 43,000kms, and my car felt like @ss forthe longest time. FOr the longest time, no matter what i do, I could not shift gears smoothly, every shift was greated by a lurch. My guess was because of the drive-by wire or something that makes the throttle ultra sensitive.

Anyhow... I did an ECU reset, throttle position learning, idle air volume resets. (can't believe the procedure is so stupid) and took the car for a test drive.

What i noticed was my idle dropped down abit. But no more lurch. The car FINALLY drives so smoothly.. Even on/off throttle application has improved immensely. God i missed how my car USED to drive when new.

You guys should all do the rest.

The procedures are on the TECHNOSQUARE ECU website. I don't have the website on hand.

Thanks
ED

 

Most common mistake that people often have done is to install the aftermarket intake and don't perform the above procedures. Especially the "idle air volume" is a must otherwise the idle would be way too high.

 

so how do you reset?

 

I just bought a 1993 Sentra SE-R as a commuter, to save miles on my Maxima, and MY GOD, the difference in quality of the two transmissions is rediculous....


My SE-R shifts so much better, I love it..

to bad it only makes about 110 hp at the wheels...

Auto or stick?

 

does this procedure also work for the earlier 5th gens?

 

both are stick...

probably, but your tranny is so much better than the 6 speed,

are you experiencing some of these problems with your 5 speed?

-vq

 

I believe the procedure only works with the models with drive-by-wire ('02 and beyond). And yes, it made a difference in my '02 responsiveness to throttle changes.

 

I did the reset on the ECU, but on the other things, how the heck do you know if you were successful? There is no flashing of the SES light or anything.

 

Why is the 5speed much better then the six speed? I like the 6speed better... except when it grinds going into 3rd... but thats getting fixed. what did they change in the 2k2's that the tranny dropped in quality?

-Chris

 

Agreed. the 5 speed tranny in the 95-2001 maximas is about 300% better as it is linkages and not the crappy cable shifter.

Its smoother, and feels like a million bucks. The cable shifted 2k2/2k3 feels like @ss.

BTW.. drove my car yesterday all day long, and it still feels a lot better than before the reset.

When you do the ECU reset, the CHECK ENGINE light should blink (fast and slow) which indicates that you did it properly.

 

You need to redo the sequence of resetting until the the light flashes as illustrated in the procedures.

BTW, the prodecures are for the 02-up w/drive-by-wire electronic system on both auto and manual models.

 

had a '91 SE-R 5-speed for over 10 years. Unbelievable how much better that car shifts vs maxima (or any other manual Nissan). The Original SE-R was a ball Nissan should never have dropped.

It is sad when the flagship has a lesser feeling manual.

I love my '02 max 6-speed, but I loved my '91 SE-R more!

 

How about a link to this?

 

You'd rather drive in a car that's louder, more cramped, with alot less HP than the 3.5 Max?

 

That wasn't a fair comment...
The Sentra, although less HP, had a lot of potential with its SR20DE (or T) power plant. and given that its a smaller car, it handles aobut 1000x better when modded over a maxima.

To this day, I miss my mazda protege for its simplicity, and the mere fact that it would stick tot he road like glue.

A maxima is a totally different ball park, ie. Japanese Caddillac STS. Lots of power, FWD, but a boat... and floaty as hell..

 

Did you do ALL of the resets? ECU, Throttle, Accelerator, Air Volume??

 

Yes..

I did the ECU reset first... then throttle accelerator, then air volume

Still drives good today too!

 

Actually, it was a question, not a comment. And seriously, I have very good memories about some of my previous cars, some of which could definitely out-handle my Max. But there is no way I would go back to driving any of them after living with the Max.

 

Could someone post a link to the info on how to do all the resets. Thanks so much.

 

have you ever driven a classic SE-R??

are the resets only beneficial if you have performance mods?

 

Does Nissan do an ECU reset after it performs ECU reflashes?

 

Yes. And I have to say it's great car.

 

Here is what Bryan from Berk Technology filled me in on:

"Brian,

I was wondering if I need to reset my ECU since installing the Berk intake.

Alex,

It's not neccesarry to do so. The ECU will relearn on it's own in about a week. By resetting the ECU, you are putting it back at baseline, which it will still have to relearn anyways to your climate so you aren't really gaining anything.

Regards,
Bryan"

 

for the last procedure on the website (Idle Air Volume Learning) the first 2 steps are to perform the other 2 procedures. does this mean to do all 3 at the same time in sequence? or just to make sure you do the first 2 before you do the last one?

 

fill me in....
