what he said ^

 

98s can get ecu upgrades.

 

Finally!

 

order my ECU

 

where have you been 98 can use a 96 ecu with no problems

 

take that and wind it back Maximeltman got the ecu to make his go fast. lol..
but seriously i plugged the 96 ecu in just now, and the engine turns over but it doesnt ignite. i tried a few times then smelled gasoline so i swapped back in the 99 ecu..normal again. question i have, and i know i'll regret it but is this right? or should it only work with the jwt upgrade?

 

and it is a 96 5spd ecu btw..

 

jwt is moving the necessary pins in the ecu for it to work with our 99's...so if you didn't rewire the pins, then no it won't work yet!

 

ya i know...just wanted to postwhore and bring it back...thanks bro! this will be a cool mod.

 

yup...I'm smiling a lot more lately!

 

wat about a 97'

 

lol like ill say again where have you been your not new here... 97 can use a 96 ecu
many people are using them i think they give a check engine light though?
not sure.

 

I got a 99 5speed federal emmisions. It has the 115 mph cutout, will this mod still work with it and will it get rid of the cutoff at 115? if so, i already am searching for a 96 5speed fed ecu to get modified.

 

i have an unmodded 96 5spd ecu...but jwt wants like $600 i don't think its worth it.

 

how much hp estimate will this ecu upgrade give?

 

i wasn't aware cali-spec maximas existed before 99....

 

oh us poor 98's

 

Read the stickies...It'll tell you how to get rid of the limiter...

 

This thread is confusing on the topic of the immobiliser/NATS. Someone said JWT rewired the 96 ECU to work with NATS (or is NATS part of the ECU?) and someone said the immobilizer won't work.

What's the story? Is this truly plug and play? IOW, if you get a 96 ECU back from JWT and install it in your 99 5-speed, will EVERYTHING work just as stock?

 

^supposedly. and I don't think it matters whether it's a fed or cali spec ecu btw
right now i'm contemplating getting it modded.

 

If this thread were Lazerus.....you'd be jesus

 

I have one if your interested

 

wait I don't know why everyone is so excited, someone explain this to me?

 

I saw that post about getting rid of it, I am asking if by replacing my 99 ecu with a 96, will that take out my speed limiter, i can do the snipping of wires easily and adding a switch.

 

I still don't get why everyone is mad happy about that car hitting redline, my car is able to...

 

It's not just because of the redline capability. Its what it gives them as far as tuning is concerned. Imagine being able to stretch beyond 65k if you had a 00vi, and boosted even! As long as I have owned any Maxima, I have never red-lined until the other day. I went up to 7k rpms at first and jammed to 2nd, at third I was gone! I would not do this often.

 

The remapping (air/fuel, timing? other?) for more power throughout the RPM range is what most attracts me. I don't really care about extended redline,, although 7K does sound more respectable than 6550.

 

i own an auto 99 cali spec, am i totally screwed about upgrading my ecu, i mean is this impossible

 

i suppose you have a gxe..not se =]

 

yep, no abs, less curb weight, more room for modification AM/FM CASSETTE for the win

 

Wait a second...so how does this work?

 

If any of you guys are interested i am selling my 1999 JWT ECU. Car has to be a 5speed.

 

How much are you asking for your jwt ecu zack?

 

yea .....and how much is it if u have a 96 ecu and send it in to get moddified for a 99 gxe.....ps.. my gxe hits 128-129 before the speed limited kicks in ....stock

 

also does it matter if i use a 96 auto ecu for my 99 5spd car?? thanks

 

he took the picture with his cell phone, since his digital camera is broken, if you read above.

oh and sorry, i just had to make a correction, custom is spelled with a 'u', not a 'y'

 

yeah im only interested in the fuel/timing boost does this only apply to the 5-speeds?

 

LOL, off his cell phone

 

great news for the 1999 Crew !

 

I sold it to zazon. last week.
