JWT ECU delivered about 40 minutes ago, along with that damn stock 98 auto ECU.

HO-LY-CRAP. This thing is sick. First test was from about 4000rpm in 2nd gear, ran it out to 6800 because I forgot that I can go MUCH farther now... bang it into 3rd and spin the tires HARD. My jaw falls in my lap. I pick up the cell, call Brian and Jason and leave hysterical babbling voicemails about how badass this thing is, I hang up and start flogging it again. This time I ran it out to 7000, trying to see where the rev limiter is now. 7000rpm and it's still going strong. Slow down some, into 2nd at 5000rpm and trying to find the rev limiter this time. Rev limit hits at an indicated 7300rpm and I hit 3rd gear and roast the winter tires into 3rd almost as hard as I do 2nd gear with the stock ECU.

Then I take it out to the freeway by the luck of the irish I've got about a 1/4 mile hole between semis with no one near by. Here we go. In 2nd from 50mph to about 75, into 3rd spinning them on the highway, running out third now, third gear goes up to 110mph!!! This is on stock sized tires as well, not my shorter-than-stock 17" tires. Ran it up to 110 and back down to 50 a few times and then on my 3rd run I notice that I'm not going much of anywhere even though the tach's pulling thru 7000rpm slowly. Damn relay, my MEVI isn't open on this one, at 7000rpm the difference is plain as day. So I chill out for a few minutes and just cruise. Jason calls me back and I get off the highway and drive home.

Now I just have to get my MEVI working without the relay so I don't have to worry about my MEVI only working 3/4 of the time.

So the verdict is, JWT ECU and MEVI is frickin' sweet! I'm in love with my car again.

EDITED for spelling and grammar because I was high on adrenaline at the time.

 

so.. umm..
when are you going to the track?

 

glad to hear it...

 

Prediction: 13.61 @ 102mph w/a 2.0 60' on DR's. 13.49 with slicks and a 1.8 60'.

 

time for me to start saving.

 

congrats, that is one fast n/a max!!!

 

Lucky bish!

 

 

Neal did you hug your delivery man???

We are heading to Byron on April 5th. Should have some good vids for you guys!

 

dammit, whens JWT coming out with a ECU for the 97-ups. Im seriously thinking of picking up a mevi as my next mod too


eric

 

Hmm, time to save some money and wire up some type of switch to the CEL! =P Having a 97 sucks! But ofcourse, JWT will have ECUs out for the 97+ cars really soon!!!

 

You're making predictions out to two decimal places?

(Not trying to be mean, Craig, it's just that engineers find this sort of thing funny.)

 

Sounds good. Mine should be arriving this afternoon sometime. Of course I'll be able to spin them in 3rd...............only because it's raining and will continue to do so thru tommorrow night.

Neal-
Can you tell a difference at part throttle 2000-4000rpms?


Dave

 

Your getting me all excited just talking about it. My VI has been working flawlessly with out a relay. You probably know how I have it hooked up.

 

whoa...and i thought my G-force ECU was good. sheesh. i still have to short shift my maxima since i don't have the variable intake and my rev limiter is still at around 6,700. time to hit the track neal!

 

It's actually a 6500-rpm limiter, the tach is what is off.


Dave

 

Well, what do you know. My wife just called. She went out to lunch with a friend and guess who stopped by? I guess I'll have to go to Fed-Ex and get my package tonight.



Dave

 

95/96 5spd + MEVI + JWT ECU = KILLER 3.0!

 

You need to add that comparison to your sig.

 

hope your package didn't go through the terminal i work at.

 

Damnnn.. your working your motor hard there.. 110 on 3rd yr. So you were at 7300rpm.. Wow that's a lotta heat there.. It's only a matter of time now til...... J/k

 

Damn glad SOMETHING worked out for ya Neal!

 

yay! You go!

 

how much are you guys with the MEVIs paying on average for EVERYTHING to do with the MEVI? Also, is it difficult to install? Im definately leaning to this as my next mod, also, where can you pick one up (website?), ive heard theres about a month or more wait for one....

thanks


eric

EDIT: Also, what are the average gains to the wheels?!

 

Congrats!

Because the tach is very inaccurate at WOT, especially in the low gears, maybe you can verify the 7200 rpm limiter by setting your shiftlight (if you have one) to something greater than 7000rpm. Otherwise a dyno could verify that you can truly go above 7k.

Despite not appreciating the BS Ben had been feeding me, I decided to keep the JWT ECU and think it is great. You really get a nice little extra ooomph starting at midrange. I think it really is a must for 95-96's with MEVI.

 

now you wonder why i have been dumping all this info on this great combo congrats on finally getting everything squared away. you will enjoy the ride thoroughly. lord knows i do. After all that wait i am sure it is worth every dime and every second. again congrats, you are going to have some great times in the up coming season.

97

 

sorry, steve has spoken b!tch.

 

99

 

you will have to take me for a spin next time your in town

cant wait to see the track times

 

i hear you nealoc. first time i took my car out for a spin with the jwt ecu, i didn't come back home 'till 2 hours later. the ecu makes the car pull so much harder in EVERY gear at EVERY rpm. WOT in 1st and 2nd is scary (no, i'm not a p*ssy ). even when you're not on the pedal, you can feel the gained power - when cruising (rpm below 3k) and i step on the pedal i can feel the car pulling harder than b4. with the stock ecu the car would feel weak if i didn't down shift when cruising (rpm below 3k).

personally i think the jwt ecu is the best bang for your buck. it was the only mod that made my jaw drop.

nealoc, what oil are you running? time to put some amsoil 2000 20w-50 b/c you will want to pound on your car every time you're behind the wheel. glad things finally worked out for you. peace.

 

I use Castrol GTX 10w30. JWT ECU is a great mod even shifting at the old redline, the torque gain is great, I can only imagine what it would be like with USIM instead of MEVI. For reference I lost about 17ft-lb with my MEVI vs USIM.

 

Yep, even with 100% humidity (drizzle) and a very low baropressure, the gain in torque from 3500-5000rpms is very apparent. Like Neal, I lost about 3-11 fwtq and hp from 3000-4800rpms with the MEVI. I actually gained a little power from 2000-3000rpm with the MEVI.


Dave

 

Wow - I'm converting to 5spd soon.

With the 5spd and MEVI, exhaust, SC, and Y-pipe - My times should drop substantially if you were puling a 13.9 with the VI and Y-Pipe.

Looks like the JWT is on my mod list this summer also now.

 

I have an old dyno of a max with I/Y/E/ECU. The torque the car makes is sick. We are talking like VQ35DE type torque. 3-4 years ago Biomax dynoed the JWT ECU vs stock 95/97 ECU and gained an average of 5whp/7wtq.

 

so are you guys saying there would be a very great torque increase with the stock USIM combined with JWT ECU and exhuast?

thanks

 

sorry to poke my head into a 4th gen thread

but why not just plug a 2k ecu into a 97-99 with the MEVI?

 

VI - ~$550, Misc Parts - $100+, Peak HP gain about 10HP, Gain at redline about 40HP (but with the stock intake manifold you shift way before redline.) Check the group deals forum.

There are no Gains until after 5500 RPM and a slight midrange power loss. That means you are only seeing gains for about 1000 RPM with the stock ECU. However with the stock Manifold you shift before redline, with the MEVI you can shift at redline and enter the next gear at a higher RPM (and higher HP)

Personally I don't think this Mod is worth it unless you can get an aftermarket ECU w/ raised rev limiter (~$500). Even then it is of limited use on the street since you can't really begin to use its power until 60+ MPH (top of 2nd gear). But for 1/4 mile guys and those who love highway power it could be the ultimate N/A mod.

Nealoc Any plans to dyno?

EDIT - I meant to put in this dyno comaparison of stock IM vs MEVI put together by SteVTEC

 

STFU b!tch.. once again you are talking out your ***..

you can use a 96 ECU in a 97
