Ecu...............

2 Da Max

iTrader: (2)

lets see, intake y pipe, pulley[ well thats up to u] uhm maybe u should get a ecu.

2 Da Max

iTrader: (2)

actually forget the ecu u should definitely get a full catback to get more power out the car first

opps.. i have catback and intake.. after them too....

if u want the best power mod..get turbo!!

Its goin to be ECU. Honestly, I could not feel any real gain when installing the full catback,or udp. When I put my ECU in, I immediatly felt a gain. To me, it was like the power of the y pipe all over again.
I know the UDP and catback gave some gains, but theywerent noticable like the ECU or Y pipe.

those with ECU do you have a MEVI? if not did you get the raised rev limiter?

Terran

iTrader: (6)

If you don't have and don't plan to get a MEVI, there is no point in the raised rev limiter. There isn't any reason to go up there without the shifted powerband. If you don't need the raised rev limiter you can also get the less expense and less downtime of technosquare.

ECU hands down, get it with a raised limiter for the mean time until you get a MEVI...

97WhtSE

I say ECU and MEVI.

well if you get the MEVi, it won't be like the ECu where you have to wait a while with car down before you can drive it again., and with the MEVI you will have a faster car and highways, since it is a top end mod.

You dont have to wait on the ECU if you purchase a used one from a Junkyard and have that one modded.
MEVI is a great mod, but it has issues ranging from RPM switches to the dreaded butterfly screw.
MEVI is basicly useless without the JWT ecu and the raised rev limiter.

i have a chance to get the mevi very soon but i was looking up the gains with one and they dont seam all that great for all that money... it really doesnt seam to be worth 500 bucks..

Terran

iTrader: (6)

I don't think it's really about the gains so much. It's more about the shifted powerband. If you want a highway beast, go for the mevi, if you like the lowend more don't.

ok apart from the raised limiter what else does an ecu upgrade get for yu

SlackR237

Yeah I'm curious about this too... How does an upgraded ECU really help with performance??

Flava_24/7

iTrader: (46)

The MEVI is a mod you do once youve done all the normal bolt ons.
The ECU upgrade consists adjusted A/F ratios and advanced timing.

naijai

well after what i just went through tonite my y-pipe is coming in and start saving for that new ecu

headers and ecu and mevi.

what r gains like w pathfinder TB?

Zipp028

iTrader: (3)

yeah the pathfinder TB sounds like it might seam to be a good mod any one have dynos or tell about there experiences once they put on the TB?

i drove a mevied and ecu car and it was insane and felt awsome. massive fun!

I think MEVI is less gain by itself than ECU by itself. With MEVI you lose the low end. MEVI really shines at WOT in high gears. WOT on stock ECU has a rediculously rich A/F and therefore not very powerful. Also, the lack of an extended redline means that the longer plenum effect only takes place for about 1K RPM's. I have a 5Spd ECU on the way that I got cheap. Now I have the ability to run the auto ECU once my swap is complete and wait to save up for the JWT upgrade all while having no downtime on the car. Definitely the approach I recomend.

vsamoylov

the fuuny thing is the maf tube that holds the maf sensor is the same size as a 2k2 maf sensor tube but the 2k2 maxima got the bigger throttle body. but on the 4th gen maxima, after the maf sensor tube, all the other piping nad tubes that are in front of the throttle body are smaller than the actuall maf sensor tube. so the same amount of air gets through the maf sensor tube but less gets to the trottle body. on vq35, this is no longer true because everything is the same size. just some info.

UDP then ECU

TAPOUT

iTrader: (5)

PF TB makes a hell of a difference for top end, and opens up the flow big time. With all the mods I have done, that is my latest, and it perked up everything. But I'll tell you that nitrous is the best next mod. If you do it right, there is no problems, and you are instantly credible against anything on the road. When was the last time you smoked a Corvette in your Maxima ? I did it 3 days ago.

mevi you do loose alot down low, but after 5000 you gain about 40+ horses. That is insane. SAve up for for mevi and ecu. do it at once, and feel it!

burn more gas

Flava_24/7

iTrader: (46)

Not to be an ****, but do you have a ECU upgrade or a UDP?
I have both, and honestly the ECU makes more of a difference then the UDP. Im not saying the UDP doesnt do anything. I know it frees up some power. Just feeling the weight difference between the two and its obvious.
But I felt more of a power gain from the ECU.

Niice!!!

Your very wrong. I'm not being offensive here. The reason that the ECU reprogram has such potential is that the stock A/F at WOT above 4K is very rich. Leaning out the mixture creates more power because thats simply the way an engine works all while using less gas to make that power. JWT/TS sets a moderately agressive A/F in their reprograms(I think between 12:1 and 13:1 near redline). The only reason you might burn more gas after the mod is because you can't control the rediculous urge to feel the insane amount of power that your N/A grocery getter has.
