rb25 with z32 ecu

[virus77]

I was blind, asked a stupid question, nevermind.

What year maxima are we talking about here, not that the z32 ecu stuff is complicated but plug and play sounds better!!!

1992-1994 VE30DE DOHC

[virus77]

And its a direct plug and play, not just the o2 sensor part? none of the ecu pins need to be changed?

And im assuming this would be the type 2 board from nistune?

See I told you lol Me and Carl H (I believe) talked about this about a year ago. The maxima seemed to be a easier option because of the single O2.

I hope something comes out of this! If I had time I pull up the rb25 ecu diagram to compare wire for wire. but if we can start confirming and have a few ppl actually up and running on them that would be a huge step

[vsaini]

honestly.. the o2 sensor is really a minimal concern.. you just bridge the 2 inputs together.. hell the damn 02 sensor doesn't even really function most of the time... the ecu ignores all that **** most of the time

[virus77]

The o2 sensor part is not my main issue, its the following pins swapping...for the RB25DE(T) based R33's these are the wiring modifications:

R33 pin 19 to Z32 pin 34R33 pin 105 to Z32 pin 110R33 pin 110 to Z32 pin 105R33 pin 112 to Z32 pin 114R33 pin 114 to Z32 pin 112

R33 pin 57: cutZ32 pins 29+52 : join

if I could avoid this by installing a dohc ve30de ecu from a maxima it would make a cleaner/easier install... no harm in making things easier...

plus I've located a 93 dohc ecu locally for $60 bucks so im gonna be rooting for this right now lol

Give Jim Wolf a call before you get this. Like I said earlier, I can't remember if the ECU I'm running is a 92-94 (I can't remember the year range, but it HAS to be specific). Call them and verify it. I got mine a while ago and sent it off to them to tune. I'm pushing around 500 with this ECU.

[virus77]

alright just got off the line with JWT

They tune the 92-94 DOCH ecu only which would be the SE edition maxima with the VE motor not the VG...

it comes with a single O2 like the skyline, runs the Valve timing and requires NO REPINNING...

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?

Here is a list of compatible ecu numbers I got from the site.... I am not responsible for this not working... merely my research

Yea there you go. Hope that helps you guys. I actually thought a lot more people knew about this.

[Neejay]

Ok, so the 92-94 Maxima ECU can be used, but it MUST be tuned?

I wonder if I shouldn't just buy the JWT tune and be done with it for now...

[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.

[MATTs14]

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..?
