My local shop, Adrenaline Motorsports out of STL, told me that a professional tuner comes by every now and again and does a reflash tune on the 09-12 maxima's that gains 30 hp and 30 lb feet of torque. This tune is only done if you have intake and exhaust. Just curious to see if anyone has any input on this? If it is true, what kind of experience do you have with it? always wanted a reflash on my 07 Civic Si, but never got one. Let me know, thanks

 

lmao!!! best youll get is 3-5hp for a tune, come on son

 

hey if the guy can prove those gains with a dyno go for it. I agree with Westwood though it'll probably be on the lower end

 

well, seeing as the '09 Maxima motor is not quite the HR ('07-'09 350z) which only made 306hp, and that was Nissans highest tuned 3.5, i find this unlikely. i love the '09 Max but i just don't see those gains without some serious work involved.

 

paired with an intake and exhaust and a reflash they saw gains of 30-35 hp. and its a reflash. reflash of ecu and a tune are different. read the post

 

reflashing an ecu means installing a different TUNE and/or optimizing the current one.

 

ok, so who has a reflash? the reflash on the 07 civic si showed gains of 15hp and 15 lb ft of torque. proven on a dyno. thats more than 3-5. all i want to accomplish is finding out who has a reflash and what are the gains? I will find out more from the local shop and prove the power gains. they are a respectable company and work on lots of nissans. I find it hard after 9 years of dealing with them that they are wrong. they have an in shop dyno as well. and the last tuning day a 09 max got the reflash. with a combo of intake+exhaust+ reflash they showed 30 hp and 30 lb feet of torque gains on those three mods alone.

 

id love to see a 7th gen with a reflash or tune, if they're that confident about the results hey why not go for it man I'm really curious what you'll see at max WHP.

 

A reflash would add next to nothing. Cobb tuning did their accessport for the 350Z and the results were next to nothing. For turbo cars there is more opportunity to make extra power with a reflash or piggy back system.

 

theres no way this is true. if it is please show me so i can do it =)

 

I am only going by what the shop said. I am ordering my stillen lip on monday, I will ask about this then. I am not confirming or denying what I have been told. Only relaying the information to the others on the site. I dont feel that it is out of possibilities, but I am not planning on doing intake and exhaust within the year so only time will tell. I will share what I am told on monday. thank you and goodnight

 

I was @ Forged Performance on Saturday for their annual dyno-day. I spoke with Sharif, the owner, about tuning a Maxima. He has not done a tune on one yet mainly because of the CVT but is VERY interested in giving it a shot! As we talked about pricing I found that a flat-rate of $695 would cover everything from Up-Rev. Long story short, I won the 3-hour dyno-tuning session that was raffled off We hooked his lap-top to the Max and dumped the ECU file. Like I found out when using a Superchips Cortex on my Frontier, Nissan's infinite wisdom provides 12-15 different ECU numbers for each vehicle! However, so far there are only 2 for Maximas. He is sending the file to Up-Rev and should have the return file in 1-2 weeks. I will post updates as this goes down. I hate being the guinea pig but somebody's got to do it

 

Sneekyfast, what are your current preformance upgrades? Congradulations on winning the free tune! that is awesome man. Thats the free hook up and I am glad a 7th genner got it so we can finaly get to the bottom of this reflash/ tune business. keep us updated as things progress, but I am sure you will be very happy with the results. I want you to prove that there is more than 3-5 hp out of the tune of our motor!

 

Did someone figure out a way to dyno the CVTs, or are we still just pulling numbers out of the nether regions of our imaginations?

 

Whether or not any accurate numbers can be had is still a mystery. We can however still use the dyno, sniffer, brick file etc. to adjust timing and air/fuel mixture for optimum performance. Realistically we won't see absolute peak numbers as the tranny will shift for us @ 6,250rpms or so. Luckily for me I won't have to pay for this experiment

 

I met Sharif down at ZDayZ this year, really nice guy (they brought some insanely powerful Z's and a 600+whp WRX as well). That's awesome you won the free dyno tuning session man. Keep us posted how it goes, as I can hit up Hill's Garage up in MD since they use Up-Rev tuning software as well. Props to ya for being the guinea pig If I won a free dyno-tune with Osiris software, I'd jump at the opportunity!

 

Yeah, he is super cool and obviously knows what he is doing. He's approaching this as a "challenge" and has experience in dealing with several other transmissions that like to "self-help" on the upshifts... LOL! We had already been talking about this, so when he called my ticket out for the giveaway and saw me walk up, he started smiling. He promptly grabbed his lap-top and started dumping the file. He was happy to see that Nissan had only used 2 different numbers for our car's ECUs.
I guess I'll probably remove the third cat and resonator before we tune it and I might even throw a set of Cory's spacers on it. I already have the BOP's so they will probably impact more than the spacers. Heat-soak should not be an issue for our intakes, however air-velocity might improve a little.
Like I said before, peak numbers are not the object here (however they would be nice) and his dyno usually reads a tad soft, but optimum performance should still be attainable

 

That's awesome man! Hell, even 10whp gain throughout the rev range would be nice (especially since it's free lol). The RL y-pipe might be a good choice too before getting the tune done. RL also has HFC's for the Altima V6... might be worth asking RL if they could work on the Max as well?

Either way, really look forward to hearing how your Dyno-day goes man

 

same platform so i don't see why not

 

Exactly, people seem to forget this. A road tune can be done also. The dyno is the issue if you are looking for numbers. But AFR and timing can be safely achieved by a road tune. Still, the difficult part is finding someone to tune the Max. I wanna say if you can tune a GTR, you can tune a MAxima. LOL.

 

Has anyone heard anything? I would love a reflash or even a full tune!

 

Scheduled for mid-January

 

Have to see it to believe it

 

im sure the 7th gen will get big power with a tune because i know FOR SURE im burning RICH because of the fact that i remember a few times i got a CEL and when i read the code it said sensor 1 bank 2 - too rich. Which I believe is due to the fact that with all these mods im sure the engine is getting way more air flow into the manifold thus the injectors trying to shoot in more fuel to make up for the extra airflow.... with all the mods i have im sure the VQ should push out an extra 30hp because we need to keep in mind the VQ in the 09+ maxima is he HR motor with a single Intake manifold and a lower rev limiter so im sure the tune WAKES up this engine

mods:
Real CAI
UD Pulley
BOP
Manifold Spacers
Headers
Y-Pipe
Catback mandrel bend magnaflow exaust (with electronic cutout)
+2 Timing advance
100Shot NX w/ Fogger

 

same engine as the VQ in the altima but the ypipe and flanges from the altima EM have slightly different bends...but for all that why waist ur time and money when you could just unbolt the cats take out the **** inside rebolt them then put the o2 simulators on and call it a night...save urself $500

 

nice man! keep us posted....i had a tuner from CT call me up to tune my car but i told them no because im not doing a all motor setup and i dont wanna waist $600 just to waist another $600 in 6 months

 

yeah a tune would definitely help this car, when I did my dyno runs the shop owner showed me the AFR and I am burning super rich. question is how the fk to you dyno tune the damn CVT, and does removing the ABS relay really get the CVT to stop freaking out when it redlines?

 

If someone can tune this car it will be a BEAST!

 

Still curious on the dyno thing and CVT.

Same engine as the L32 Altima and they have more conventional trannys, so I'd say if it shows gains for them, it is safe to say it will show gains for you guys. Moreso the Altima coupe, since the early L32 sedans had lightly different intake manifolds and throttle bodies.

 

why do you want dyno a family sedan? this is beyond me! its auto its is slow this car is meant for some hott wheel dumped on its nutz and u cruise with! and its auto cvt! its not a race car guy remember that! go buy a new sti if u want go fast and tune all thia reflash crap

those 30 hp will make a dicference when your going o the supermarket ull waste more gas then me hahaha lol

 

LOL! I don't go to the supermarket in mine

 

its funny you say that, cause anytime I see a 7th gen dumped on coilovers with tons of negative camber I ask why the hell did they waste their money on making the car look ugly on top of negatively affecting performance.

to each their own brotha.

 

Why do folks with Honda Civic's want to dyno a stock 1.6L making barely 120hp?

Also, you obviously don't know anything about auto vs. manual transmissions at the track. Auto beats 5MT or 6MT ANY given day. If you can post better timeslips with a stick vs an auto, I'll shut my mouth.

We know this car isn't a racecar. Anyone who thinks otherwise is just kidding themselves. If I wanted a small car with a chintzy interior, harsh ride, 6MT and a highly boosted 4 banger, yea I'd get an STi. Guess what... that's not what I was looking for in a car, much like many of the members here who own 7th gens.

Like Ghozt said, to each their own.

 

I do, but I get there fast

 

this is my 5th 7th gen i have had mostly all the colors i had a different one every 3 month this one im keep becuase i like the car.. i just feel like this forums focus must on issues and all this crap i was seen this car on some wheels stanced out guys doing nuce systems and see these cars ok air body work still that for this car to make serious power worth looking at you need to go boost and this trans cant hold any power

but each there own i still doubt ull make 30hp on a ecu reflash with just exhuast mods! lets be serious turbo make that with ecu reflashs on stock turbos what makes u think ull make 30 hp gains! this isnt a 3.7

 

hey Papies...the guy who claimed 30 whp gains (iFuxwituz) with a tune has way more than just exhaust mods...lol...it would really help for you to read the entire thread before you respond.

 

Most VQ engines (including the VHR37) will see a net gain of about 20-30whp from intake, exhaust, HFC's and a tune on a DynoJet or Dyno Dynamics. I have numerous friends with both 350 and 370's who saw roughly the same results from Hill's Garage in MD (premier Nissan/Infiniti tuner in this area).

Have you seen other car forums? All forums have a plethora of posts regarding people b*tching about their car's issues and things they wish would be fixed.

One last thing... the 3.5L VQ engine is actually MUCH easier to tune than the VHR37. The VVEL system on the 3.7's has yet to be hacked to allow additional gains. Tunes on the 3.7 are only utilizing the cam phasing on intake and exhaust cams. Once someone figures out how to integrate the VVEL system into their dyno tunes on the 3.7, that motor will crank out some more ponies N/A.

 

ok guys your right im the dumb one sorry im curious to see what power you guys can make prove me wrong power to you! i want see the tuner make power then will see how that trans and everything else reacts

 

Anyone have a stock/baseline dyno? And if so, how did you dyno the CVT?

 

Please forgive my newbie question, but why has no one tried the Bully Dog Triple Dog GT Gas Gauge/Tuner?
