sup org,

i have a 99 se i called jim wolf and to my surprize the 99 is not tunable due to the factory alarm is this so?? if so can i tune my car without sacraficing the alarm? JWT also mentioned that the connector is different and pins are in different spots. i have minor bolt ons a cai and a full exhaust factory cat. im just looking for a mild tune; a/f ratio speed limiter and rev limiter. any help on this matter will be much appreciated. THANKS ORG

 

VAFC2

 

The immobolizer system Nissan designed makes it hard for JWT to make the ECU for 99s. However, they were able to make it work in a 99 with a 96 ECU...I vaguely remember the details on that, search that one.

But for the wants you have, why not just go with an EU? You can control your a/f ratio, rev limiter, etc to your desire, for less than a JWT ECU can be had. Just my .02

 

EM-U, VAFC, Diffrent year JWT ECU Swap

 

the eu you speak of is that like a piggyback? and how would i go about finding one

 

GReddy Emange Ultimate

 

ok, so ilooked up the emanage ultimate and it looks like exactally what i was looking for i love this forum THANKS AGAIN ORG

 

Yes, but do you have the skills to install the Greedy Emanage Ultimate, and then tune it?

Install writeup can be found on www.VQPower.com

 

Still what about for some of us who prefer a bogless extended rpm limiter?

 

My limiter is silky smooth.

 

i actually planed to have it dyno tuned i want to squeeze every last bit of performance out of my vq

 

did you ever get to raise your rev limit with your emu?

 

Nope.

 

how much are emanagements?

 

lolz wut?

 

is there any other 99 with a emu?
why aren't you able to go past the stock limiter?

Have you considered using a jwt ecu (modded for the 99's), with just the exteneded rev limiter, and sprikling the emu on top?

 

Thats what I want to do.

Anyways... So what I heard they have done in the past was take 96 ECUs and mod them into 99 ECUs??? And was this JWT? I don't think it's TS because I gave em a call a while back and they said they won't do 99 Maximas..

 

Save the $ for a turbo or supercharger kit

NA tuning the 3.0 is not worth the $

3.5 swap is also more cost effective

 

I don't recall anyone mentioning the cost of modding a 3.0 or even modding options period.

Thanks for the useless post, actually two useless post, because of me jumping on you.

Anyways... Aftermarket 99 ECUs... Who has had them? Would love to hear some current/former owners chime in here...

 

Believe what you want, research what you want, in the end you will still be wasting your money tuning your NA ECU to get what? 15hp?

There's a reason why products like Nistune/Bikirom are not compatible with the A32.

But since you're that tough internet warrior, go ahead and hook up the Greddy Emanage and tune your vq30 to 300 dyno hp. Can't wait for that graph.

 

The Wizard is supercharged, so a raised rev limiter would most likely overspin the supercharger and shorten the life of the bearings etc.

The EU has the ability to go past the stock limiter.

 

i understand where your coming from but, i really dont want hundreds of horsies i just want something respectable. i will be happy with only 15 hp. i only need to go 65 mph but i wanna get there quickly and i want to have fun doing it.

 

If you have 00VI/I/H/E on a 4th gen and tune the AFR and dial in the timing and rev limit, you should see more than a 15whp gain on the dyno.

Tuning is optimization, it makes the most of what you have, so if you throw more parts at it, you can change some settings and make more power.

IMO, tuning N/A-wise is oriented more to pushing the limits of your tune to squeeze power out of your engine (since it's not in any imminent danger) whereas with boosted cars (assuming stock internals, pump gas) you are tuning to prevent the car from blowing up (ie; pulling timing to prevent knock).

 

^^ so... basically i should install the 00vi before the tune? and i read somewhere you dont see any low end torque from that mod (thats just what i read) and im looking for the low end torque.

 

Since someone else will be tuning your car once the EMU is installed, install ALL your mods that you plan to do first, then EMU, then get it tuned.

 

I believe there are a few other 99's out there, but can't recall who at the moment. I've never heard of a 99er with a raised rev limiter via EMU, only JWT.

Why?? Beats me. The EMU was/is programmed to do so via DandyMax's instructions, but it just doesn't work. I even had my tuner call DandyMax on the phone as tech support while my car was in his possession, and the two of them couldn't figure out over the phone why it wasn't working. I suppose I should send my map to DandyMax and have him take a closer look.

Yes, I've considered having JWT modify my ECU just for the raised rev limiter. When I called JWT about 6 months ago, I spoke directly to Jim Wolf himself. He kept trying to persuade me to ditch the EMU and go with his ECU exclusively. I kept telling him no way. He said just for the raised rev limiter, it would still be the full $750.. At that point I just forgot about it because I was in the process of building my Supra and modding the Max was a low priority. Now that the Supra is built, I'm getting back to modding the Max.

 

This is true. I'm already over spinning my blower based on my calculations due to the extremely small pulley that I'm running.

I still plan to extend the rev limiter somehow or another, add a few goodies I have planned, and break 400hp at the wheels.

 

So you tried to add fuel at fuel cut per Dandy's instructions and it didn't work? What happened exactly?

 

[s3] - grow up you really sound like an idiot, we're not discussing about what motors to use or what mods to have, I can't believe I've succumbed to even replying to you TWICE, but I won't participate in your foolishness anymore, help the thread or get out.

Sooo lucky!!! The guy I talked to was telling me it's a no go for 99's.

Just got off the phone w/ a guy (Phil?) @ JWT he said no way, only thing that could possibly happen is what I thought from before... Taking a JWT '96 ECU and having things rewired.

If I'm fooling with ECU wiring I minus well just do EMU only or hell full VQ35 swap outta a 04+ so I can use osiris... mmmm... osiris.... TS-F... Sooo many choices!

Still looking for that white buffalo who has done the rewiring for their '99

And +1 on the problem w/ extending the rev limit via EMU... This is news to me

'Cef have you dyno'd w/ a "Silky Smooth" extended rev limit? Maybe things have gotten better over time and that little dip isn't as pronounced as I've seen on older dyno sheets.

Bottom line:
I see the only benefits of using a ECU vs. EMU is the plug and playability (which may not exist in the case of a '99 owner) and not having that little dip @ like 6550rpm for extended rev limits.

 

You kids and your Maxima's

who said i was a kid?? if your referring to the lack of knowledge you really dont understand the point of a forum and really need to have a nice day

 

Not you, the other kid with the attitude and his ferociously tuned NA Maxima.

 

i get what youre saying....obviously boost or 3.5 swap is gonna yield more power than something to tune with. but if youre gonna boost or 3.5 swap, youre probably gonna wanna get something to tune with anyways...so why not. doesnt matter which order you do it in. chances are he'll max out his n/a potential and wanna boost eventually anyways.

 

retarded 99 ecu's.. i think this is the only year that doesn't have a raised rev limiter!

 

do i hear t trim with a 2.69" pulley?

 

u are gonna need tuning equipment anyway u look at it.

 

Correct, however tuning/dyno time isn't free

 

yea like $200 is really gonna kill ur funds for any kind of forced induction.......

 

Don't mess with the evil red USIM monster...

 

I'm a former owner of a modified 96 ECU that I had in my 99. Never tracked or dyno'd it but the raised rev limit, etc sure felt good with the other "power" add-ons I had. (MEVI, UR UDP, Cattman headers, Greddy SP2 exhaust, Fidanza flywheel).

The only 2 complaints I had with the ECU in my 99 was that if I left my car running in the winter to fill up with gas, as soon as I unscrewed the gas cap, the car died. Other issue was the idle was raised to around 900-950rpms. Not sure why it did that with the JWT ECU.

As an added bonus, for anyone who has the crappy 99 key that breaks to easily, if you have a modified 96 JWT ECU in your 99, you could use a 95-98 Maxima key. Whatever JWT did to make the 96 ECU work in the 99, they disabled the feature that links to the chip in the key.

I sold mine to i30dvr. 97_Roadrunner is now the owner of it. Perhaps you can contact them as well to get their thoughts.
