I don't know how many of you guys are using 2nd gen JWT upgraded computers, additional 8hp, but I got few. I was wondering if the 87 ecus work in 85 and 86 2 gen maximas?

Am just curious how many of you guys are interested in tuned computers. I even got the programs for turbo 2nd and 3rd gens.

 

how much and who in the world are you?

 

Hey Ned, Glad you came by. As was said via email, I'm not sure if the 87-88 ECU's will work with 85-86's. The only way is to test them out and see.....except we need to find out someone that has an 85-86 to test out the 87-88 ECU.

Everyone, I've been working with Ned. He might be able to do aftermarket ECU programming, much like JWT does for our cars. I actually was bidding on a Z31 JWT N/A ECU he had on ebay, and this sparked interest in maybe making an ECU for 2nd gens. I know I would be very interested in this.....but it also depends on how many of you are legitimately interested as well.

S

 

Id be interested!

Also, there is different impedence on the injectors for the 85-86 and 87-88? You would need some sort of resistor right?

 

I am interested if they are cheap....8hp on this car is not worth that much to me....let me know, I have an n/a 87 SE.

 

The JWT one yields only 8hp....but from my impressions of what Ned has said, he can tune it to get more than that out.

DJ, where did you hear that there are different impendences between the 85-86 and 87-88 injectors? I'm kinda interested to find where you've been getting all your info lately.

S

 

HAYNES!!!!!
Im not sure what the chilton says.
Scary huh?

I know you hate the Haynes,but I like it better than the Chilton. Just for the fact that certain ECU codes are not in the chilton. And it has better pics than the chilton. Usually I just look through both.

 

The Haynes manual doesn't have both code checking procedures in it! It has only the 87-88 ones! Man I'm telling you, the Haynes isn't as good as gold as you think. Your going to run into something that is wrong in there. Besides....best manual anyway is the FSM.

S

 

FSM is the best TRUE

But I don't have one. Dont know where to find one yet. But the chilton leaves out a lot of things for the 88. Thats why I look at both but like the Haynes better. Maybe it because you have an 86 and I have an 88.

 

FSM is usually on ebay every few days/weeks usually between $5-20

 

Ok geez guys. Chilton, Haynes, whatever.

Let's hear more about these ECU's.
1. Any ideas on what we can expect to pay?
2. How long will they be available?
3. How much more than 8hp is possible?
4. Will it affect mileage?
5. Would I have to use a higher octane fuel?

 

$200 each ecu, is a good price. The ecu can not produce more power than 8hp if the engine can not breath any better, the exhaust is very restrictive. Am yet to see a non turbo car making monster power by just installing upgraded ecu. Use common sense.

It won't effect the mileage if driven normally, If racing yes if will consume more fuel depends if you have exhaust and intake upgrade. Turboast4 soon as you start modding the car you don't care about gas consumption anymore man in fact the engine has to burn more fuel for more power.

 

So we need to send you our ECU?
Then how long will this take?(reprograming)
I have a 2.25 cat-back sys and am planning on a Z31 intake manifold and injectors. Would you be able to reprogram to that degree or should I just send a Z31 ECU?

 

Yes I understand that mileage will go down; you obviously need more gas to make more power, but I use my car everyday and go on 6+ hr. road trips often. I just don't wanna get stuck getting 12mpg or something ridiculous, that's all. Lemme know if maybe I'd be better saving my money on another mod, if this might not be for me. My Max is a stock 87 auto. And BTW, it's about time somebody started making mods for these cars!

 

Yup, I guess it's good to point out the ECU upgrades like these are meant to work with mods on the car. They will help on a stock setup, but only can do so much. Also mileage is a little irrelevant to modding cars....however...doing stuff like opening up the intake and exhaust will help in mileage, but when changing ECU to match that work with more aggressive fuel/timing maps, that may cancel out. If anything, you might see the same mileage as your normally get, if not, there maybe a decrease...but it shouldn't be excessive. From guys I know that have done ECU's on thier newer cars, they really haven't notice a drop in mileage.

S

 

I have the ecus here. There is no core charge, you keep your ecu. I send you complete tuned ecu for your car. Like I said on the low rpm the car will not consume more gas. If you whant to have stock maxima then keep it that way. Simple ecu upgrade on bone stock car will not make your stock car a street sleeper its common sense. I think its realy cheap $200 for complete tuned ecu no core charge.

If you go with Z31 non turbo manifold and injectors I can use the Z31 program in maxima ecu that way it will work good.

 

As Ned said also, 200 is really cheap. Most guys are paying $500, plus core charge.

S

 

Ok, last question I promise!
How long will these be available?

 

so how do you have the ecu programed now? Is it programed to help certian mods more? for example, can you run N2O with this ecu? Or is it just a basic program that changes some fuel maping and raises the rev limiter? Is it set up to work with no mods or moded cars? Can you use a different intake manifold and the ecu still be optomized? Just wondering, this does sound like a really good deal though.....I know this same ecu for my fourth gen would cost way more than $200. also is there any turn around time? JWT is netorious (sp?) for taking a long time.

 

Payment method?

 

You must ***** yourself out!

 

This will be available for while don't know how long but there is no wait time, I allwready got two ecus ready and I can get shipped. Yes there can be tune for NOS systems. Stock maxima ecu has really lean fuel mapping like 13:1 across. My first stage is the JWT copy. THey bumped it to 12.5:1 and bumped the timing map 2deg and there you go extra 8hp. Now I can tune the chip more agressively to get a gain of 10hp plus.
My software shows two rev limiters one at 6600rpm and other 6400, Its pritty high so my idea is to leave it stock for safety reasons, after 6600 rpm vg30e does not make more power but just puts the motor in danger.

I need to get some fotos here. let me take some.

I got the ebay account for payment or Money order

 

so I see you are advancing the timing by 2 degrees....would we need to run a higher fuel grade than 87 with this ecu? I am guessing the advance of the timing is making up for you making the air/fuel mixture more rich?

 

Is this because of the Haynes debate?J/K

 

cardana24: If you are runing 87 octane fuel in your max why are you even debating performance tuning maxima??? 87 octane is crap fuel for any car, it leaves deposits like crazy plugs the valves up with varnish. You whant to run best fuel possible for best output. JWT recommends premium fuel with all their upgrades. If you are cheap and can't afford the premium gas then get out of tuning culture.

 

I have no clue who you are but I have been on this forum for a while....you just started posting today. I run 87 octane in my 87 Maxima because that is all it calls for from the factory....the compression is only at 9:1 and its not boosted from the factory so you really dont need anything higher. I am not cheap by any means but this is an 87 Maxima.....I have over 15 grand in my fourth gen.(above and beyond the purchase price), so until you know who I am dont pass any judgement on me, thanks

--I think what you are trying to sell is a good product, I am just trying to find out more about it....I know plenty about a JWT ecu for a fourth gen. I like my 87 SE but in all honesty it is a beater compared to my other car...I would like for it to be faster but in my personal opinion I dont want to spend that much on a car that is worth $500, so when I ask questions about gas grade that is why I do it....

 

Any chances of getting a hold an 86 ECU....or could I find one and send it in to you...though if I get that JWT ECU, I can probably send my stock one in.

S

 

Hakentt
I would be interested in an ecu!!!!!!!

 

I can get any ecu for second generation so its not a problem. Maximase86 you are bidding on that Z31 ecu like crazy and you are not sure if it even going to work in your car.

cardana24: I got 3rd gen and it calls for 87 octane but it runs so much better with 91 premium. I have been a member here but I never posted anything because am mainly into Z32. 2nd gen is not that bad of a car but its true the car does not worth much thats why no one makes tuned parts for it.

If anyone needs a tuned ecu now I can do custom job for him or just upgrade it with JWT chip. Email me if interested nedimhaken@hotmail.com

I will post some fotos

 

Yeah, I know....but I figure if it doesn't work, I could always sell it anyway.

S

 

Hey Ned,

Do you mind post something about this on the 2nd gen Max group on yahoo? The very bottom link will take you there. You might have to sign up and all, but you might get more folks interested.

S

 

Ned, I was posting on the 2nd gen group about this, and there are some questions that we're brought up that I figure you could address. So here it goes:

Where did you get all the ECU's...and are they via legitmate means? This is asked because there have been many shady deals before here on the org.

How do you reprogram the ECU, with what interface/program?

Also you state that these work. If they don't work, or perform as advertised, what would you do to remedy the problem?

Again these were questions raised by other people. They want to know the legitmacy of this before saying anything, and I can't blame them for that.

S

 

I get all my ecus from local salvage yard, I have my own testing tool and I test the ecus before I buy from them. Nissan ecus are good and its rare that they go bad. I do have a warranty on them for working condition, now when it comes to chipping I will not refund anything if the person is not happy with performance, because what if the person never changes the spark plugs or something and it happens to go bad when he installs the tuned ecu, he would think the ecu is not doing well and request a refund, I do the same thing as JWT, they don't refund money. JWT dont take **** back and it takes them forever to fix it. I sold many on ebay and never had a problem so...

I use the japanese software to tune the chips, same thing that JWT uses.

I will be posting some ecus on ebay soon.

:

 

I guess you could verify the reprogram by printing the screen for the ign/fuel maps of the stock vs modifed ecus. I would also think if your ecus were a fraud like other have said, your ebay feedback would be bad.

 

Well the owner of the 2nd gen board has his doubts. I guess a good way to find out how legit these are is in the ECU I'm getting from you. I can put it up on the dyno and do a comparison between the two ECU's if I have to. Though I like the idea of Jeff's idea of getting a print screen of the fuel/timing maps..and doing a comparison.

S

 

Well since the owner isn't banned he should voice his own opinions here. He visits anyway

 

If there is no trust then don't buy from me. The people who bought from me where happy. YOu can't realy see a 3 deg. of 3d map change on print screen. The screen print does not work with this software and this site does not support the big pictures taken by dig. cam to clearly see the map.

 

lol, no worries. I got an ECU coming. People trust me, so if I'm happy with it, that should put them at ease.

S

 

maximase86> I got a hold on some ecu wiring shematics from 86 max and z31. Seems like Z31 uses different location from ecu for ignition coil. I printed bouth and am sending them to you.

 

Alright, so I actually need to redo the pin out on the ECU for this? Thanks for sending the schematics, I will look them over.
