I installed the mevi today (not wired up) And replaced my rear gasket because it was leaking oil. It took me and my buddy about 3 hours to do the whole job in the cold. RESULTS:

Im very pleased to say, All the results of everyone saying the mevi loses power at low end or mid range or w/e. Its not the case for me. I acually feel a more powerful pull in all gears. I barked 1st and 2nd chirped 3rd. Never In my life would I be able to chirp 3rd. My friend who I let drive my car Has banged 1-3 gear before and after mevi installation. He tells me the same thing that There IS NO POWER lose and the car barks the **** out of 2nd. He says it clearly that the car feels more powerful.

What I did, Well my old manifold was soooo fulled up with carbon and oil that air was getting really restrictive. The mevi was fully cleaned up inside, I cleaned the EGR (I believe its called that), the idle sensor thing, The back side of the Tb plate, And the ports that lead the air into the engine block under the manifold its self also cleaned my Stillen intake because god knows when was the last time that **** was cleaned. Over all the rir flow increased and thats Why I strongly Feel that That my car was lacking power due to all this carbon and oil build up.

The negative:
My idle is at 900, Someone told me to reset the ecu and it will correct this problem.
----
The lobes on the cams looks amazing! In perfect shape.

Im not saying dnyo sheets lie but I was very curious about everything and all this power lose when I didn't feel anything but power gain. My next research will be when I test the mevi to open up at 4.5k or 5k Which will pull harder. But looking at my tach, I noticed slamming 1st to about almost 7k pushed the rpms back at 4200 and 3rd to 4000. I had to keep an eye on the road as well Im pretty positive for best results 4.5k would be very good to regain power. In the end its each to his own. Im very satified with the results!

 

barking gears isn good for your tranny and motor mounts, dont do it to often or else you will be replacing both very soon...

good result tho, sence you say your manifold was very dirty and resticting airflow, i am thinking more to take mines out and polish it up a bit...

 

Well I'm glad you got the MEVI installed and like it, but the fact is that it does lose power, unequivocally. Also, the best switchover is about 5200-5400rpm, any lower or any higher and you are going to be losing power. Congrats on getting it up and running.

 

I feel a DEFINATE loss of power, especially in the mid range. I'm really surprised you don't notice anything. Do you have an extended rev limiter? 5200 rpm is better than 4500 or even 5000 rpm. I've tried several different settings and 5200 rpm is best.

 

What did i tell you man? People make such a big deal about it losing power in lower rpms, but the gain in high rpms is so much more than the slight loss of low-end.

 

Neal is completely right on all accounts.

You may not "feel" the loss, but it's there and it will become more obvious with more driving, especially in the warmer months. Dynos and 1/4 MPH/ET don't lie. You loose power in the midrange, regardless of tranny or year.

 

Yes, but that little loss in midrange power is more deterimental to 1/4 mile performance than that nice gain in power from 5800+rpms. Lots of us have already shown that our cars were no quicker in the 1/4 mile with just the MEVI and some were even slower. It took the higher rev limiter and increased midrange power of the JWT ECU for us to take advantage the MEVI.

 

Hahahahah......resluts are in.....hahahaha.....congrats on the install, but you act like you have done something ground breaking. 100% without a doubt you lost mid range torque. It is a fact, it is not just some theory that it happens with the MEVI.


Oh, and I am going to have to go ahead and call BS on the whole "now I am able to chirp third". The power that you land into on an up shift is the same as it was before. I

 

99.9% of the time you reply to my threads its usually something nasty towards me. If you didnt like what I posted then please dont bother to reply. I did chrip third gear. I would know Because Im the one driving the car and I was there with my buddy when I did it. You can raise bs on me all you want, its fine to me, but Im not going to doubt what anyone else says, I wanted to see the results for myself. There's a kid in my school with a civic running 14.5 that chrips 3rd all the time. Doesnt mean he has a powerful motor his tires are just bad. I dont have the best tires in the world I spin a lot, If I had DR's It would be a diff story. Anyway Im not attacking you but please just give it a rest with me IDK why you constantly keep doubting everything I say. Thank you

 

Some else was telling me that the best switch over would be 4900-5000. Im guessing the car needs more power around 5200 like you said. Thinking about it more and more it makes more sense to open it on higher rpms on top then around 4k. Thanks nealoc

 

Yeah I hear you, I was just excited at the time And wanted to test it out
I taking it easy now and waiting to go and polish everything up because theres nothing but oil finger prints under my hood. I did polish my mevi and looks great under the hood, Im going to go out soon and clean up everything then ill take a pic.

 

What does that have to do with ANYTHING??!!

I'm not even gonna bother with the rest of the post cus the other guys already did.

 

Umm, I replaced my rear valve cover gasket... my engine has 104k miles on it Just implying that for the miles they look great, ive seen lobes on another maxima motor that has 120k and one of them were completely rounded off.

 

I see. But just sticking that in the middle of a post like that sounded incoherent that's all. :shrugs:

 

Did that noise go away?

 

MEVI without an ECU is basically "shifting" your power from midrange to upperrange

 

Nope, Still there im guessing it something else running on a pully.

 

I'm guessing all the power you recouped is from the nwe manifold being so clean, and all the other maintanence stuff you did. When you mevi is actually functional, maybe then you'll notice more of a loss in the mid range, congrats on the install.

One thing i dont understand is, if the mevi is not functioning, how can he be getting any more power? its not opening or closing! why and how is there a power gain?

 

^^ I believe he is referring to the before and after impressions of the "mid range" power only.

 

maybe so but then where does that "barking 1st and 2nd" thing come into play? idk i think this post just confuses me lol

 

That doesn't make any sense either. A filthy USIM will produce more midrange TQ than a squeeky clean MEVI by virtue of it's design.

Classic case of the placebo effect.

 

Yo... I was the friend who drove the car.

Man I definitely noticed an all around power increase. Pulls harder up top EVEN WITHOUT the MEVI being hooked up. I can't wait to feel that difference now. The car from 1st - 2nd drops off insane... all the way to about 4100 which is way to much... thats why I figured the MEVI opening at 4500 would be best, all that time wasted getting to 5200... when it could just open earlier.

Call BS and then take the flag you raise and nicely place it in your rectum.

I drove it and the car chirped 2nd but you had to really hit it hard.

Now it spins into 2nd and you hear a nice little birdy chirping into 3rd. Call it on us, but then drive your *** here and witness it.

SMX isn't lying, the kid at school with the Civic... actually chirps 4th and ran a 14.7... if SMX had the tires the Civic had on, he'd be chirping gears in other peoples cars.

Don't worry SMX... kids like I30tMikeD just need a severe beaten... either with fisticuffs or being blown away by lets say... my car?

 

The earth is flat until someone proves me wrong.

 

I can see nobody believes me, I wish everyone lived near me so they can test drive my car. Once the mevi is hooked up I will get a dnyo test done. simple thing, you need good tires to keep the power to the ground.

 

i believe you....

STOP .ORG BULLYS!!!!!!1






j/k

 

So you know that your old manifolad was dirty and clogged yet you don't think that's the reason you feel the power gain. Interesting. Look at every single MEVI dyno without an aftermarket ECU and you'll realize you're wrong.

 

Its already been discussed where the optimal switchover point is

 

I never said it didnt, I said "Over all the air flow increased and thats Why I strongly Feel that That my car was lacking power due to all this carbon and oil build up."

Therefore since I cleaned it, I can feel more of a response and also being the that mevi is clean inside.

 

I would think dyno numbers and quarter mile times are more conclusive than being able to chirp gears. SMX, once you get the ecu upgrade you will have a very good combo. Congrats on the install.

 

Now i definitely know this is BS. I won't even waste my time replying to the rest of this post.

 

I'd love for you to come down here and TRY to give Mike a beating. The MEVI isn't even hooked up properly and yet you try to deny what's been proven MANY times. I just don't get it. Speaking of rectums, I bet yours hurts a lot.

 

i probally could chirp 5th if i never got off the gas when i shifted. but good job on the install

 

am I being e-punked?

High 14 sec civic's

Chirping 4th

High School kids

Non functional MEVI's that gain power through out the whole rpm range

Throttle body cleaning

4500 MEVI activation points





Yep, you guys are the shiznit

 

Here is a dyno of my car a while back. The red line is what the power curve looks like with the butterfly valves not opening. Hmmm.....look at all that power up top

 

Im raising a BS flag. It doesn't fit my rectum but it certainly fits yours.

 

wow guess you have the only mevi in the world that produces more power than anyones else`s.. i had swapped back and forth between the usmi and mevi and the mevi sucks me-range hands down.there is no more power increase with the mevi cloesd at all on the top end.its just like having the usmi.. you need good tired to keep the pwoer to the ground. ther is no way you can chirp 3rd with bald tires with the mevi there is no power in the mid-range. go get the dyno and prove to yourself there is no extra power

 

the only power gain he is feeling is from him having a clean manifold. when i did my mevi you should have seem the build up inside .but when i put the new one on (good looking out nismology) i felt a gain only due to all that gunk being out the manifold and me cleaning the trottlebody and airfilter

 

what the hell is going on in here???? This thread is worthless
