Does the Mevi help only on 5spd or does it help on automatics as well.

 

It only helps 7 speed semi-automatics with a clutch.

 

If I'm not mistaken, they work even better on autos

 

I thought it produced better results on a 5 spd.

 

works better on 5spd, the auto shifts too quick so you cant really take the gears to higher rpms... by time your mevi kicks in, shift next gear.

and low end loss will suck with auto.



u just answered your own question

 

wow, you're on quite the roll today!

 

autos have fewer (and thus longer) gears so they can stay in that peak HP range above 5000 RPMs longer than a manual

 

unless you get an ecu upgrade, you will get back most of that loss.

 

Not if you get a JWT ECU and shift "manually"...

 

will shifting "manually" harm the engine/tranny?

 

mmm hmmm

 

Do you even have a MEVI? If your car is in tune, it will feel very close to stock. If anyone doesn't believe it, they can drive my car and I don't have my TS ECU anymore.

 

I just found this old thread, so can anyone just become decisive and tell me weather the mevi intake manifold will be worth putting on my automatic maxima? Cause I'm about a week from ordering it. I really need to know i dont wanna spend close to 500 dollars for no reason.

 

Yes it is.... search more

 

mevi is good for high ends in both auto and 5 speed, no doubt. however..

if you plan to drag race with the mevi on, you will need to do more mods soon because mevi kills your torque by bunch. i was so pssed with the torque loss at first, so i went on and did the rest of my mod list after that and now it feels great.

if you plan to just roll with mevi, it won't make a big difference to have lost that low end torque, but your high ends driving will be very appreciable. this is a plus for rolling with mevi on the highways, both auto and maxima. then you will also hear from a million of us saying over and over again: If you get mevi, make sure to upgrade your ecu to get most of that torque back; preferrably, get the jwt's 7200 redline ecu so you can ride on the elongated mevi powerband.

 

My rpm switch broke shortly after I got it so the mevi didn't open up more then once. But the time it did it was freakin sweet. I put the old manifold back on and only noticed surges that the mevi eliminates. Mevi creates a much smoother, quieter sound. I'm auto by the way and I liked it, just need a new rpm switch.

 

get a 00vi, and call it a day.
a little more intense to install but you dont loose as much of the mid range power, and you can get one for 500.

 

wher can i gt a rite up uv 1 uv these?

 

hey just want to ask, do you actully need to install a relay on the rpm switch? i didn't put one in. but it works fine, I just install it not to long ago, about a month now.

 

No relay on mine

 

So are you saying that with the mevi intake manifold you loose the the jump edge in the beginning of a drag race, unless you have mods installed.

Posts #'s 338, 341, 347, 352 are the reasons I was telling you not to do as you were doing, so there's the answer to your email.

 

that's right, right after the mevi install, the jump is still there, but not as strong as with the stock intake manifold. however: after modifications, you'll be able to compensate it greatly especially if you have a 5 speed. anyways, take off is the key to the qm drag race, but after take off, it's all mevi...

 

Only one case where someone did NOT lose any low end w/MEVI.

 

out of the blue question realting to mevis, JWTs, and autos, i dont even have an auto so just wondering

but is there anyway to chage the shift points up on the transmission to reflect the new redline with the JWT ecu?

 

By manually shifting it ...

 

on my 5 speed stock setup with mevi, i remember going redline on first gear, then drops back to about 4700 rpms to catch 2nd gear. then 4600 catching 3rd.

after i had mevi coupled with the jwt's 7200 redline ecu. my shifts would catch around 5000-5100 right on. after i complete my mod list, shifts were never caught up below 5200, governing my driving on the mevi's powerband. this was good until my clutch started slipping like a btch... rpm's would be higher but with stick-slips.

 

I think he was referring to autos

 

Zach?? someone else? I personally talked to Sean05 and he said that he did not feel any low end loss wutsoever. No dyno to prove, but maybe it was such a minimal loss that it just felt the same to him.

 

Unless he has a dyno, good is a "feeling"? Yes zack342

 

Hey wen you're in your ride, "feeling" is all that matters rite? As long as it feels good

 

Ok .... ... IMO, Actual #'s are better.

People in civics feel good when tehy hit the "sweet spot" :

 

So Zach had no loss, but wasnt that with the stock ecu? i remember he was having problems with jwt, but cant remember if that dyno was with it. Assuming that dyno was with the stock ecu, could we say that he had a lowend gain by adding the mevi?

 

.. explain yourself, that makes no sense He has bot w/ and w/o JWT.

 

ahh, nevermind. I cant even explain myself.

 

JWT ECu did nothing for him ... Check the thread... something happened after 6500 and the power went --->

 

thats a hilarious smiliey.

ECU isn't necasary, I don't have one yet. But it would be nice, once the MEVI opens my car runs into the rev limiter really fast. Hopefully Greddy will get the timing advance and extended rev limit working for our cars on the EU
