Maxima TECHNOS ECU

Supposedly increases the rev limiter to 7100, removes the speed limiter, changes the timing and fuel maps, adjusts the drive-by-wire system to keep throttle flap open and adjusted air intake constraints. 20hp increase with HKS muffler....Should be quite a bit more than 20hp with I/E....Looks like my next mod.

ECUs for the 95-96, even the early production 97s..now this upgrade for the 2001-2003..I would just like to state, that with my 98..I feel throughly violated, us 98-99s have no options, which really hurts us if we were to get the MEVI, only thing I know of, if to get the AEM P+P system, and reprogram everything yourself..siGh..

Actually, at this point, it is only for the '03 since it has a different ECU than the '02. So, looks like I'm waiting until they "do" the '02 myself :(

It's too bad we can get a Exhaust Temp gage, Manifold pressure gage, a fuel mixture gage, and a mixture knob, like airplanes. We could adjust as we drive, for the optimal performance, or fuel economy.

Any idea where I could find the part # for my ECU on the car? I emailed Technosquare about whether the reprogram would work for my I35 and they thought so, but wanted to know my ECU part #.

You could either take the ECU out (passanger side, under the radio), or have it hooked up to a Consult II, which will tell you your P/N...

Hey Metaorbit, Nice lookin ride! I too am after the 02 I35 ECU. Just sent Danny at Technosquar ECU pinout values and elictrical diagrames for our car. I am trying to locate an inexpensive factory service manual so he can compair it to the 02 Maxima. The manuals on CD rom cost $210 from Infin. parts! If you get any leads post or e-mail me,[email protected]

Hi 240sx, If you are asking what my red line is it is 6500 rpm. The upgraded ECU will kick it up too 7100 and remove the top speed gov. along with fuel maping and allowing the throttle to open all the way. also tweeks the timing and leans the afm to 12.5 at wot. By the way, have you noticed anything with the rear tower strut bar, my nephew has a 95 240sx with a skyline moter (turbo). Nice ride

Well the rear strut tower bar stiffened up the rear alot. I autocross alot. Also when the back tires do break free, it makes the rear end a little harder to predict. After I put it on I went drifting and the first drift i ended up countering too much ended up doing a 180, I evenually got use to it though. It is also a cheap strut tower bar and it came on my parts car free. Nick

Just sent my ECU for 02 I35 to Technosquare to be flashed. I had sent them the info. they requested and said it was now possible.It will take several days to get it back but I will let you all know how I like it. After this is done the down time should be much shorter,maybe 3 days.

I will, I have been trying for 3 months to get the right info to them, they are great to work with as I am not tech. or very mechanical, just an Infinity enthusiast. Now that it is in their hands I am getting excited.

Got an e-mail from Technosquare today 1-22 and they were already able to flash my ECU. They will ship it back on fri. 1-23 and should be here about 1-26. This is sooner than I expected so of course it will go in the same day and I will let you all know how I like it.

Thanks for the compliment!

I'm real interested to see how the Technosquare ECU turns out. Given any thought to some dyno runs?

I recieved my ECU and installed it today 1-27. If I can find a dyno in St. Louis I will. So far no luck but there has to be one somewhere close. First impressions with only 100 miles. 50 miles highway 27.8 and climbing mpg. Drove the other 50 in city and co went down to 24.2 but I could not resist getting on it alot. First gear manual shift goes to 6500 rpm faster and when I shift to second it is about 69 or 7000 grand and it pulls strong all the way. Their used to be an a sort of power lag at lower rpms 1500 to 2500 but I dont notic that any more. This is the subtle part, in other words the drivabilty. From 4000 grand it seems stronger like something kicks in. I know this is all seat off the pants and not many miles but that is all I have right now. I will try hard to be objective and not let my expectations carry me awy. Gateway International Speedway is just accross the miss. river from me, might be a dyno in that area. Have over 500 miles and will say everything is true, I really like the upgrade.

Also I was having to reset my ECU about every 10 days because of the y-pipe, catback exhuast and CAI. It also smelled like it was running richer after the mods. With the flashed ECU I won't have to reset it anymore and it already has lost that rich smell. I know, nothing scientific here just nose and butt. Look at above post Meta. Take care

Another update, 70 more miles hwy. 30 mpg, I like that! Pulls strong and then at 3000 grand I could feel a real surge and at 4000 grand a deffinate kick, very strong. I really liked that. This was not my imagination. I did this about 5 times and each time that same kick was there, very strong.

Yeah, this may be my last upgrade other than struts/shocks. I'm still kicking it around and waiting for all the kinks to be worked out first. Pretty positive reactions so far....

Yea I know what you mean, maybe next year or so Volk lit. wt. wheels and some better tires but for right now as an older kid (56 in june) I'm having too much fun and running out of extra cash. I really wanted a Maxima, great car but the I35 fell in my lap, new the sales guy and he gave me a great deal but couldn't resist modding it some, Had a 69 440 GTX in younger days and the Max and I ,beleave it or not come very close to being as fast. My GTX stock was 14.3 1/4 mile,auto. Now thats a hoot, Nissan, better built smaller engine 15.1 or mid 14s stock, Wow, technology Oh forgot to mention 7 too maybe 12 mpg in the GTX, 23 too 30 in the I35 VROOOM!

LOL....

50's is not too old to have fun in an import sedan. I'm not a teenie bopper either at 38 ;)

Would of loved to have driven that GTX. I look through ebay at them from time to time. I have driven a '70 Road Runner with 400 that was decent. I had a 350+hp '78 Cutlass years ago and I know the Maxi is faster. Comparing late 60's muscle cars to the 3.5L VQ is pretty funny. Most of those cars were barely in the 14's and the faster ones would get low 14's (Boss 429 hemi Mustang had a "best" of 13.9 I believe with slicks).

I am hoping to order one before the March meet. Intake and Exhaust are just not quite enough yet :D

Man with that post you sent me back 35 years to daydream land. Cat jumped in my lap and scared me back to reality. THere was a magizine called muscle car 69 that spected all those cars out and that is how I picked the GTX. Thanks for reminding me. Check out http://www.classiccars.com sometime. Has all those gas hogs for sale, I would still like to get a GTX when I retire,Hey came to think of it thats not to for off---Yes! Well gotta play guitar for church early, take care

I'll have something soon enough. There is potential in all of them. Wish I had kept my '67 Camaro now....

Not sure what my second resto will be (first was the Camaro), but I'm sure I will have fun with it anyway or simply buy one in a few years that has already had a frame-off ;)

Take care and good night....
