'02+ Maxima ECU Cracked!!!
hey guys-
i am currently AT technosquare's shop.. they're workin' on my Z..
i'll get to get more info about your maxima ecu today... and to see if there is any more info i can get for y'all--

So let's say an avg. stock 6sp (i think i read this was done on a 6spd) rates at about 205hp at the wheels. According to the dyno above, the new ecu gives 213hp at the wheels on a stock 6spd. A total of about 17hp at the wheels when added with an intake. The intake will give around 3-7hp alone at the wheels. So it looks like the new ecu does what it should with the added air (about 12hp at the wheels minus the intake). 12 is about 15 at the crank, which is good...don't get me wrong. However I don't think I will be spending $500 - $600 for 15hp at the crank. I wish all those well that do, however.

simple as that.
If you're only looking at a peak increase then you're selling yourself short. Any mod you do for performance needs to be studied based on it's gains throughout the entire power band. This ECU mod basically redraws the hp curve of the VQ35 to make it look like it should have looked in the first place. Some of you may only see about 10+ hp which doesn't seem like much for the price but in the real world this mod will make the car go faster down the track which is far more important than a peak dyno number.
I dont know why we bother, people just dont seem to understand. Its average hp/tq that wins races not peak #'s. You could put a car that peaks at 800 hp on the track against a car that has 600 peak and the car with 600 can destroy it considering its average hp throughout thr rpm band is higher. Why do you think nitrous cars are so fast w/o having insane peak #'s?
UPDATE!!!!!!!!!!!
PRICING for 2002/03 Maxima ECU upgrade is now announced!!!
it is $495
YAY.
WE still need 2002 auto/2003auto/2003stick beta testers here in so cal.. anyone interested please let me know..
as concerning the 2000/2001,1999,1998,1997 ECUs, its not like they dont want to modify those ECUs. its just that the phsyical hardware is not present to modify those... and it probably would not be business saavy to try to create five different hardware interfaces....
more updates soon.. but think the 2002 6speed ecu will go on sale very soon..

www.technosquareinc.com is the website.
You also should have noticed that they still need 2003 donors for both stick and auto, meaning they are not available for us 2003's yet.

ok i should have done a search i guess....but i think your wrong about needing 03 cars....the thread says it is for 03.....
as a matter of fact reading the posts i thought the car tested was an 03 stick with an intake and modified bpipe?....
i know he said they were looking for 03 donors but that would be a misprint i would think......i dont know i got an 03 6spd and im ready to buy......if its available ill let you know how it works out when it comes in

well is it available now?in the site it says coming soon......ill buy it and tell everyone how it works.....dont really have the time to dyno first though.....maybe i can get cutlr7 to drive down and dyno it somewhere for me while im at work....see what i can get done

3. Electronic Throttle Body control, getting 100% WOT
4. Variable Timing control switch over
5. improved gas mileage due to efficent motor running
6. rev limiter raised as a buffer zone to prevent fuel-cut off engine damage
7. overall driveability of car is increased. its more fun, at every RPM band
8. will work even better with other modfications you have.. depending how bad the maxima's stock ecu is in trying to provide feedback values to getting the car back to stock a/f program after sensing changes to
intake and /or other mods.
9. ECU reprogram will NOT SHOW UP on Consult II... no one but you will know that the ECU has been reprogrammed... there is NO DIGITAL ID TAG.
Con:
1. time down due to sending in the ECU for flashing. typically it is three days for entire process. 1 day to take out and fedex to them. 1 day to mod and fedex back. third day receive and install
2. some say cost is an issue, but that is subjective
3. for ultimate optimization, ecu should be tuned for each every car, but typically this only results in +1 or +2 more HP than the regularly sold high-performance fuel mapping...
4. closed loop stock programming is not changed (0->3k) for safety reasons for the engine.. it is due to cold start up to allow the engine to warm up.. and typically, you only need the power when spirited driving, so that means above 3k in the open loop areas, right?
comments? thoughts? be my guest and post
i will return shortly

Is the timing change similar to org members having their timing bumped with the consult II?
Is the dip at approx. 3800 on the dyno power curve due to vtc switchover, and if so, can this dip be moved to different points on the power curve via ecu programming? If it can be moved via ecu programming, what would seem to be the best point on the power curve to move it to?
What kind of an increase in mpg are we talking?
Maybe it's to soon to ask this since an auto ecu has yet to be acquired, so please keep this on the backburner..... Could this be an alternate fix for TSB NTB03-023, or does TSB NTB03-023 alter shift characteristics also if the tranny is auto?
If and when you folks do aquire a auto ecu, could you please let us know if the shift characteristics can be altered, e.g. higher rpm shift points, harder shifts, manual shifting, etc.
If an owner wants an upgrade due to a mod, what would be the cost of that upgrade?
You sure this won't show up on a Consult II?
495 is a deal already. If this mod can get me 2mpg more and if the vtc can be altered optimally it becomes one sweet deal. Add in altering auto shift charactersitics, and it becomes the Mona Lisa.
Thanks in advance for the replies.

Ice, I think we could use another Thread title change. Could you make it '02+ Maxima ECU Cracked!!!

Thats good news on the pricing! I was expecting $595.
Does TS have a dyno in house? And are they planning on doing anymore tweaking prior to the release?
Thanks,

I'd also be curious to see what kind of results we could expect to see on a fully modded N/A car. If the car has an intake, headers (which aren't shipped yet), Y/B pipes, CAT, muffler, UDP, advanced timing (which I'm assuming that the ECU upgrade would override that mod), and some sort of air/fuel management, what would the gains be then. Alot of people know that ECU mods can help a partially stock or stock vehicle, but to see the gains on a fully modded N/A car would also be cool.
Cheston... ask them about this. I'll be a donor if they want some numbers for a more modded car.

You won't ever see the VTC operation on a dyno because it is gradual and not just a on-off switch like Hondas and some older Nissans.
Yes it can be changed and it has been changed.
The blip you always see on the FWD VQ35s is the intake manifold opening up and bridging the plenums.

Donkey has TOMEI cams, but I think they are still a closet trophy collecting dust, so no feedback yet.

Well, do they work? i dot know... rasearch says yes. Cost... I'm talking to a custom cam maker who may be able to bring down the price if we give him specs... remember, those cams are NISMO, so R&D costs a re built in
Is the timing change similar to org members having their timing bumped with the consult II?
the consult II is limited in the amount of timing change, as well as where the timing changes can occur… the ECU reflash can alter the variable timing change-over, and yes you will hit VTC on the dyno.
Is the dip at approx. 3800 on the dyno power curve due to vtc switchover, and if so, can this dip be moved to different points on the power curve via ecu programming? If it can be moved via ecu programming, what would seem to be the best point on the power curve to move it to?
yes. Dip will/can be changed. It will be moved lower as to take advantage of the power of the VQ.. so it engages a little bit sooner.
What kind of an increase in mpg are we talking?
typically I saw ~2 mpg increase above 3k rpm driving (when the car is out of close loop) but you will not see any gains if you’re heavy on the throttle all the time testing it. its more of a gain when you drive ‘normally’
If and when you folks do aquire a auto ecu, could you please let us know if the shift characteristics can be altered, e.g. higher rpm shift points, harder shifts, manual shifting, etc.
shift points are not altered. That is on the tranny control unit… although it will raise the rev limiter. So when you are manually shifting you can maintain gear longer.
If an owner wants an upgrade due to a mod, what would be the cost of that upgrade?
if you want custom tuning, that will cost more.. but typically the ECU reflash will work with most NA modifications (headers, test pipes, catback, intake)… unless you are adding an extremely large amount of more air into the system, then the ECU will probably have to be reprogrammed…
You sure this won't show up on a Consult II?
the code itself is not digitally tagged.

on a fully Modified maxima, I would except a fully NA modded car would be quite high… ~20-25 fwhp.. but im not ‘in the loop’ any more with Maxima motors.
but I would assume you could benefit from your NA mods significantly with a tuned ECU program..
i am expecting Technosquare to release the full version modified ECU this week-- they are building the webpage with FAQs, Dyno numbers, and install/deinstall instructions....
updates soon!

WOWWW GOD!!! what a post... 
it will void my waranty on my 2k3 maxima? my tranny will be better and stronger? the redline will be in 7100 or 7300? and the more important... how many $$$? thanks guys...

- TCS muffler (angle cut)
- Warpspeed SS Y-pipe
- Custom b-pipe 2.5 w/o resonator
this won't void it any more than any of those.
this has nothing to do with 'strengthening' your tranny
redline will be increased, it's not 100% clear how much (7100 seems to be the number but the dyno didn't go that high)
I'm not going to answer the money question... you can scroll up a posts and see for yourself. This thread would only be 1/2 as long if people actually READ it rather than asking the same question for the 4th and 5th time.
