we really need a reflash from these guys. some poeple on the other forums are sending emails to them so we can get a reflash....here's the one i sentQuote »hello there i am a member from nissanclub.com, me and other members are very interested in doing a reflash, i'm pretty sure other members have contacted you already about this. i'm also wondering if you guys could do a 2.5 reflash also, i mean tuning the 2.5 should be alot easier than you guys might think, a lot of members would love to get the most out there 4 cyls and you guys seem to be good with nissan tuning and we're hoping that you guys would help us out.i hope you guys would take this into consideration.-Tammer[/quote]these people did a reflash for the 3rd gen 3.5, start guaging interest guys![email protected] them an email. NOW!

bump!

so no one wants to remove the top speed limiter, no V6 owners wanna rev to 7000RPM? just send an email, we need to gauge interst...even if you're not intersted just support the cause

[theoctopussi]

I thot piggy back systems where nissans route?

[shift_mikey]

Speed limiters? I like to keep it under 120 anyway (or whatever the speed limiter is set at)

Rev-limiter? Good insurance for a stock engine. leave it alone.

How about horsepower gains?

FEATURES:

REV limiter modificationWe found that with the ECU upgrade, more power can be gained with a higher rev limiter. A 7100 RPM (stock 6600 RPM) rev limit is set to take advantage of top end horsepower, while still providing a safe protection for the motor.

Speed Limiter RemovalThe stock speed limiter of 236 km/h (148 mph) has been removed.

Ignition Timing Map AdjustedThere wasn’t much room for improvement at the bottom end since the ECU retards a lot of timing by using a feed back system in stock trim. So, we have added more timing at the mid range - high end to take additional advantage of higher-octane gasoline. This aids in improving torque from 3000 rpm and up.

Fuel Map AdjustedStock fuel was set to detune the top end horsepower. We discovered that the car runs extremely rich after 5000 rpm. Air to Fuel ratio (A/F) of 10.8 was found right before the stock rev limiter kicks in. Cleary, Nissan was trying to detune the power output at higher rpm to discourage the driver from hitting the rev limiter. For the performance enthusiasts, however, this is unsatisfactory, so we set the A/F to 12.5 all the way to redline to provide adequate power gain while still maintaining a safe margin.

Drive By Wire AdjustmentThrought our testing we found, the drive by wire system was program to never fully open (throttle flap) when you smash the accelerator pedal. In fact, it actually closes the closer you get to the rev limiter, by as much as 20%. This restricts air into the motor and causes HP and Torque numbers to go down. We have remapped this setup so when you go wide open throttle, the throttle flap fully opens and STAYS OPEN, increasing HP and Torque.

Adding to above modifications, a few other adjustments were made to other maps to enhance the feedback function which improves power, torque and drivability. The resulting achievement is a remarkable improvement in driving feel, which is more than what numbers alone can tell you. We are very satisfied with the results and are proud to release our TECHNOS ECU for this tuning-challenged ECU.

I'm in. Ive had alot of success with my ECU reflash in the past.

cool can you send them an email

[LongBeachCoupe]

Hey guys... im completly clueless when it comes to tuning things like this.... What would be the cost? (would we be able to pass one around? flash mine, then give it to another guy with a 2.5 and injen, and so on?)

Also, i see the gains they claim... Can they be verified (by you guys atleast to some degree?)

Also, im not looking to comprimise my car for performance... I am going to be paying this thing off for almost 5 more years and i am concerned about extra stress on the engine and the possible negitive effects of this mod...

Please clarify

[theoctopussi]

aye bourne, are those stats on the 2.5? *did they have that technosquare reflash for the 06 QR engine? if so, it should fit ours...

[TheBourneAltimatum]

no it was the VQ they did.

man i'm so disappointed of people not giving a **** about more power. i mean **** just gauge interest how hard is it to do, my email took me less than a minute

[Loop]

Honestly, calm down. There is no need to act like that. You have a better chance of calling them and explaining the situation. Emails tend to fill up too fast and doesn't get seen.

[adidas2go]

cool can you send them an email

done

[TheBourneAltimatum]

thanx, it seems like me and someone else only emailed them on the other site head:

EDIT: Damn it can we add this smiley as head:

I'm interested if there are not MPG loss associated with the ecu flash. I'll email them too

[TheBourneAltimatum]

lol mehdi you know that more power= less millage lol....just wait till you boost your altima...you'll be lucky to get 15 mpg....but even if you're not interested email for the cause...you might change your mind later and want to faster

[BlackNWhite]

I'ld like that but isn't an ECU reflash a big for people that want to keep their warranty.

I know intakes and exhaust are like really not a big deal warranty wise, but ECU reflash and cutting wires and splicing and things like that are warranty killers no?

[TheBourneAltimatum]

^there is no way a dealer can prove that you have a reflashed ECU...unless you tell them they'll never find out

[BlackNWhite]

If anyone can confirm that I'm down for this.

Just seems that they can hook the ECU up to a computer and they'll be able to find out that it's reflashed.

[adidas2go]

Just got an email from Technosquare. They cant do the reflash on CVT ECU's.

[BlackNWhite]

Great, so much for this thread...

[08altima35]

i just emailed, hopefully they respond

[mcheddadi]

6MT ftw I hope then

[windex]

Any explanation why they can't or they just havent done it yet? I'm gonna be pissed if its just flat out impossible...

[GreyZone]

lol mehdi you know that more power= less millage lol....just wait till you boost your altima...you'll be lucky to get 15 mpg....but even if you're not interested email for the cause...you might change your mind later and want to faster

Boost on this engine? 10 to 12 mpg at best, and of course, premium only, plan on ponying up the money for the ponies.

[Hussain]

ya i totally agree since most A/C are CVT. i'd really like to see an ECU upgrade for CVT. i mean if they can make sure throttle stays open the whole time and it will stay at 7000 RPM the whole time, that would be pretty cool

[TheBourneAltimatum]

got a reply....they wont do QR's

this is what they told me

Well, you are wrong about 2.5L tuning is easy.We have been working on the QR25 for Sentra for racing applications sowe did a lot of testing on it.There is not enough gain from stock motor as we like to see.Gains are very minimal because of its VERY long stroke,and we can'traise Rev limit higher either. (will kill piston rings very quickly)So, we are not actively marketing QR25 application right now.

If you are serious racing guy who would rebuild motor after every race,then we can work with you.

That's not what they told me.

We are currently working on the 07 model 350Z and G's right now.Altima and Maxima are on our list to work after G37 coupe.

Since the most of people use Altima and Maxima as a dairy driver, weusually have very hard time to find test vehicles, because we will needthe ECU for at least 2 weeks to extract stock data.Also every model (AT, MT, different options) have different data in theECU so we need to get hands on every single one of them.

As far as O2 sensor issue goes, we are not allowed to touch emissiondiagnostic part of the program by EPA.If any after market part causes CEL to come on, then it is not a goodproduct to use.

Someone was asking earlier whether or not the dealer can tell if you have an ECU reflash. Unless you specifically mention it, the only way they could find out was if they tried to download the flash off the ECU, something the never do during diagnosis...

[blancs3030]

I sent them a email.

[adidas2go]

This is what they sent me:

Well, if it is manual transmission or regular auto, we can work on theECU, but we can't on the CVT models.We work very closely with Nissan and they don't want us to play with CVTvehicles.CVT is not as strong as regular transmissions, so that's the reason.

that sucks...well i hope stillen makes a QR pro for the altimas... i just want to remove the top speed limiter....it might help at track when i'm done modding
