I was thinking of gettin this next week...it this a very worthy mod?how much hp?benifits..how does it work?lemme know..peace..
ps-i tried searching but nuttin..

 

I have an auto. It is noticeable, but I've never had it dynoed. Advertised to make 15-18 hp, but I think my auto eats up half of it. The raised shift points in an auto are noticeable on the tach. Also noticeable on the gas gage when you get on it. I might have done as well with a Y-pipe and a CAI. If you have a manual it should be quite a kick!

 

know what parameters the JWT ECU improves?? So far all I know of is fuel and ignition re-mapping, pushes back rev-limiter...what else am I missing?

 

I don't know exactly what it changes, but I can tell you that it is very noticable. I did it over a year ago, never once been sorry I did it. Get the y-pipe also.

Does the ECU upgrade help or hurt your gas mileage, I know the y and CAIs have been giving increased mileage.

 

im gettin my valve body done..so then it should be a real kick then..

 

Go ahead and get it.I plan on buying one shortly,It will definately help your car out.And if you plan on getting NOS it is something you will need.But I would say if you dont have a Y or CAI get those first.Because the ECU will kick a** even more with those mods.

 

DON'T use NOS with the JWT ECU alone, you will need the $450 NOS "daughterboard" add-on! if you run NOS on the JWT chip alone, you will see major damage due to incorrect timing settings!!

 

Yeah,I forgot to mention that thanks DA-Max.What I meant to say was you will need that but did not mention to say what you would need to go with it if you add NOS.Such as Fuel Pump,Injectors,Plugs,Daughterboard,Etc...Just to be safe

 

That's about it. I heard it may eliminate the top speed governor also, but not sure. Stock limiter is at 130mph. It increases the shift points on automagics by about 300rpm's. I think that's what you mean by "rev-limiter."

 

While I have the Factory Supermax, my good buddy Jonnymax said that it was the most impressive gain when he got the JWT ECU. Next best thing was a y pipe. He has an 94 SE 5sp. Also the fuel cut occurs at 7000 rpm on VE's and that would be any speed limiter. I have gone 150 in my car so I know that there wasn't any speed limiter.

 

czar,I was just curious if you can tell me WTF is a factory supermax? Some special Maxima Nissan put out that I dont know about?

 

Czar is not an idiot. Supermax is just his term because he likes his car alot. He doesn't doesn't claim "factory supermax" is an offical term or whatnot. He car is pretty super though, it's one of the cleanest 3-gens I've seen(besides mine!)

 

I dont think czar is an idiot.I was just curious if there was a supermax I didnt know about.I guess you can call me an idiot.

 

i bought the ecu and it was totally worth every penny it doesn't really hurt your milage unless you step on it all the time...cause it is tuned for performance...but it is a good investment if you are looking for performance

 

how much do they run? and yeah, i agree with czar, i've had my max over 145. maybe autos are geared differently or something. i dunno. . .

 

$550+shipping; JET also makes one for $400+shipping.

 

the ecu cost me 500 for the ecu then 500 security deposit that i send them my old ecu so after they get my oe ecu i got the 500 back ....it might have been a little less but that is about what i paid

 

I just say that to alleviate the frustration that some people have when they run marginally better times than me with waaay more mods. I have just an intake and my buddy has everything that you can reasonably bolt on to a max and his best (so far) is 14.6....

 

i'm sure with some practice he could do alot better...i have just the same amount of mods as jonnymax besides the sts plus i have larger wheels but i am sure his time could improve with time....but you did get a good time i'll give you that

 

The JWT ECU does NOT change transmission shift points.

-Kaleb

 

isn't his a 93? i heard that for some reason the 93's were slower but i don't kno if that is a fact...i don't know where i heard that but it just seems strange that the same motor on the same frame and it is slower..maybe some minor things were changed...i don't kno oh well..

 

we have 5spd sorry..

 

With the jwt daughter board can you use another brand of nos like nos,zex,etc

 

the basic thing i wanna know is if the ecu is gonna make my car go alot faster..and free up more hp and torque

 

as long as you inform JWT of the shot of ntrous you are using, so they can custom design the chip for you. Personally I'd stay with NX or NOS since ZEX has that "computer controlled" solenoid box and is sorta different from the NOS solenoid set-up(if I'm correct).....

 

How much HP and TQ will it increase a VG 5 speed and is the rev limiter raised. I want to know if it is worth the money.
