rb25 with z32 ecu

[virus77]

a question about address files

If you were putting an rb25 tune on a z32 ecu for instance. Would you copy the rb maps to the z32 maps which will be under the z32 address file or would you load the rb25 address file and maps and use that with the z32 ecu?

For a rom tune through JWT the maxima ecu is the way to go, but im not sure if nistune supports the maxima ecu though, I really dont wanna be the guinea pig either but I want nistune for sure... looks like I will be going z32 after all

The guy at JWT i spoke with said send us the ECU and $595 and they will put any tune on the ecu for your RB25

Just saving other people the hassle of calling. I am assuming the the nistune TYPE 2 board should work on this the same way it works on a z32 ecu correct?

Why do you think it's the TYPE 2 board?

Seems like, the only options are:

1) Z32 repinned + tuned/get tunned2) 92-94 J30 Maxima VE30DE ecu tuned by JWT (unless it's determined which version can use Nistune)3) PowerFC

And each time something changes, the VE30DE ecu would have to be re-tuned ($) by JWT.

[virus77]

the maximas are in the same years that the 300zx used the type 2 board and it has the same harness plug so I figure if its any of them it would be a type 2...

Most likely I will do the z32 route unless I can use nistune on the maxima ecu, jwt route is out of the question... I might just try the maxima ecu for the sake of future RB owners lol

[meet07]

this is what I found on nistune about the J30 maxima vg30e------

Type 1 boards cover the following earlier non-consult vehicles:

CR31 Skyline (RB30E)HR31 Skyline (NICS/ECCS RB20DET)VL Commodore (RB30E)VL Turbo Commodore (RB30ET)Z31 300ZX (VG30E, VG30ET) 1984-1985, 1986, 1987-1989A31 Cefiro (RB20DET)J30 Maxima (VG30E)S12 Gazelle (CA18DE/DET)S13 Silvia (CA18DE/DET)S13 Stanza / 240SX (KA24E)N12 Pulsar Exa (E15ET)N13 Pulsar (CA16DE)N13 Pulsar (CA18DE)U12 Bluebird (CA18DE)E10 March ST (MA09ERT)

Type 1 Hardware Install Sheet

This is a first for older non-consult ECUs!

You can now view and log RPM, Speed, MAF voltage, O2 sensor, Temperature, Battery, Timing and various switch settings. Diagnostic Terminal Codes can monitored and cleared. You can also perform real time tuning with this board!

This board along with the NIStune software provides consult capabilities (including Diagnostic reporting) and map tracing for non-consult Nissan ECUs

Current price is $400AUD for board, USB cable and NIStune Software (Individual Users License) and documentation set. Additionally, shipping and transaction fees may apply.

I dont know much about the old school ecu's but it seems that it doesnt have consult. Im not sure if it comes with a duaghter board or not but I dont really see how it doesnt work. Ill try to contact but last time I got no answers...

There are a few people in the states that you may be able to contact with more info im sure:

The vg30e ecu doesn't work, plug is different. The one that works its the ve30de from the 92-24 SE maximas. I need info to see if nistune works on this ecu, I'll call some of those numbers and see if I can get anywhere.

[skylinedrifter]

Does it matter if I use a M/T or a A/T Z32 ecu on my RB25det R33 or can I just adjust the romtune.

BR,

Johan

[meet07]

I coped a z32 ecu yesterday at the yard for 45 bucks..

[mobilemedianj]

it sound like a lot good luck

[mobilemedianj]

I heard its really hard....

[MATTs14]

Any updates on whether or not the maxima ecu will work?? I want Nistune on my rb25!

[virus77]

I decided to go the z32 route in the end, gotta swap like 6 pins on the ecu. All i have to say is DO IT!!!! I love my nistune

[MATTs14]

So you do exactly as it says on what has been posted on here with swapping pins? What about what vsaini posted?? I assume all of that is taken care of in the repin. IF so I'll just follow the post on Nistune's forum and do it that way.

Also did it run rich out of the box or was it a fairly accurate tune for the RB25?

[virus77]

There is a correction somewhere on one of the wires, I believe the nistune website has the correct pins to swap like you mentioned.

I started my car with a z32 mafs and 525cc injectors so I never really used a stock tune. However, I loaded the stock z32 code and it did start and idle decent, since its designed to work with a z32 mafs. I can't imagine wanting to keep a stock mafs so if I was you, I would get a z32 mafs even if you have stock injectors. This will get you close enough to run on the stock z32 maps with a pretty close "K" value. At this point you can just copy the main fuel and timing maps for the rb25 and paste them into the z32 file (I noticed the z32 timing map work like poop with an RB25) after that its just tinkering a little here and there to make her feel right at home. Nice thing is you can open up the rb25 maps with nistune running, open another instance of nistune with the z32 maps and swap over most of the variables (cold start, vtc, redline, etc..) Just remember that if you use a z32 address file you cant view the RB maps. So one of the nistune programs will be using an rb25 address file with rb25 maps and the main program with your tune on it will be a z32 address file with a modified z32 map because you are running a z32 ecu.

I'm a little confused on how to get the r33 bin file onto the z32 adr file. Any input on this?

[l0nestar]

:foreheadslap:

Read directly above from Virus77.. It requires two copies of NisTune open since you have to open the corresponding address and rom (bin) file.

CTRL + C, CTRL+V ?

[sx1and2]

rb25 + Z32 ecu + Nistune + rewire +tune = good?whats with the earlier posts about needing a specific a AFR meter?

[DrifterProdigy85]

The Nistune Type 3 board works with the VE30DET. Are you positive this is a plug and play ecu once its tuned? No swapping pins or wiring needed for RB25DET S1?

[nshort530z]

I know that this thread is over a year old, and I hate to dig it up but I was wondering if anyone knew if it was possible to modify the z32 harness to work with the rb25?? this would be awesome as I dont have the ecu or wiring harness for the rb25 but i have spare z32 ones just sitting around...

[l0nestar]

Using a Z32 harness in what chassis?

I would assume it is better to use the correct harness, for the correct engine.. It's simpler to move 4 pins than convert an entire harness, but if your up for the challenge..?

[Cjmartz2k]

Z32 uses twin CAS's, so challenging to say the least.

[DustinZ]

z32 is single cas.

[Cjmartz2k]

As in rocking a VG30dett kinda Z32? Am I thinking of the wrong car here?

*Edit--after some picture searching, it does, in fact, appear they only have one CAS. What the hell am I thinking of then? O well, ignore the crazy Polish guy and move along

[DustinZ]

Dual VTC and Dual TB and thats it. Even still has single tps with the doble linkage.

[rhd240]

does anyone know how to do this? i hear about it alot and dont know where to begin.its going in an s13 single cam car.

did the z32 ecu. repinned a couple wires no tune just plug in and drive. ran 10 times better than 25 ecu. now im upgrading the car so im gonna go with aem series 2

[mixeds14]

does anybody sell the ecus already tuned for the rbs or would it be cheaper just to buy the ecu n send it off to get tuned... if only a few pins have to be mess with, i reather get into this n buy some upgrades for my engine than buying 1500 standalone..plus the upgrades

for now anyways..

[z32pilot62]

What would be needed to run a 90 N/A ECU, with a JWT chip already socketed in, on an RB20? Just do the previously mentioned joining of o2 sensor wires, resistor in fuel temp sensor wire, and what else?

Im about to buy a 20 without an ECU but a full harness and came across this thread. Now im kind of excited to know I might not have to buy an ECU.

[240z!!!]

there is so much information in this post that is wrong its not even funny...

why is everyone so caught up with the early z32 ecu's?
im running a later z32 ecu on my s1 rb25 and it runs just like the early only difference is you use a type 3 board from nistune(and when you burn your tune it doesnt give you confirmation that its burned but it is)
http://forum.nistune.com/viewtopic.php?f=12&t=1567

and repinning the wiring is cake its only a few wires and took me less than 10 min to do including soldering the resistor in for the fuel temp, and you can get the board from andy at autovaughn performance in murfreesboro the board itself is like 240 on his site and 50 to install and i just had someone tune mine so i didnt have the cost of the cable or the program

there is plenty of information on all this on the nistune forums but they have all the fixes you can do internally instead of doing the wiring(id suggest letting whoever installs your nistune to do it) they also have all the fixes to turn off the fuel temp, the idle switch and multiple other things

or you can run a rb20 or rb26 ecu and run an external controller for the vtc (on the 26 you'll need a intake air temp sensor, which is the exact same as the coolant temp, but after a certain temp it starts to retard timing im not sure what it would do without it though)

and if you want any kind of accurate tuning tool dont go apexi neo seen it so many times it isnt funny

[txQ45]

Done three Nistune Z32 ECU's with the RB25 via re-soldering points in the ECU...
Have a few guys who have done the re pin ..
Doing one right now that the owner is going to do the re pin..
The re pin seems to be the easiest .. even tho I get more $$ to do the re-solder
Considering time to do it and the extra cost

[mixeds14]

man this is interesting.. so if u can solder the pins in the ecu would be a better choice than repined the harness, cause if u ever had an issue on one of your upgrades, say like ur turbo or injectors take a crap, u can just put ur stock ecu n other parts n still run with it...
that alone seem like a better alternative then hacking up the harness... but how much would this run n would u be able to re tuned the ecu once u get better parts?//
