rb25 with z32 ecu

[l0nestar]

lol, you guys are silly...the nistune board is updated realtime thru the consult port.

+1

NIStune uses a daughter board as an alternative to an emulator or EPROM chip for real-time tuning using a modified version of Nissan Consult. It provides faster transfer rates, realtime modification of maps, constants and tables using the NIStune software.

Also, make sure you have a wideband that works with Nistune. There is a list on their site of confirmed units (most quality units are).

Innovate LM1 and LC1, Zeitronix, PLX Devices (R Series), are all confirmed. AEM UEGO is also confirmed, but I would throw that in a dumpster =P via Nistune -> Equipment -> Widebands

sounds like i need to blow off my notes on installing a 20 ecu on a 25.

1. Remove RB25 ecu2. Plug in RB20 ecu3. Tune to Suit4. ???5. Profit

If you go to the Nistune website and download the RomPack there is an rb20 ecu tune in there to suit/run rb25. It is not perfect but it is a good starting point.

Fixed that for ya.

What do you re-pin?

[Kansei240sx]

The only thought that i have is.

If i use a Z32 ECU, do i need to copy pasta the factory map from the RB25DET ecu to the Z32 ECU to use as a base?

If so how do you go about doing that.

I plan on using the Z32 ECU with a Nistune board, and already have a Zeitronix wideband for it.

[jdmae86]

im pretty sure you can download the base maps from the nistune website... thats what i have heard... i do not know if it true

[l0nestar]

Sorry guys, not to be a d!ck, but I edited some of my posts and removed some info. reason: I don't want to spread mis-information / un-verified information.

I will have solid details up 'soon'.

[Carl H]

lawlz, love it!I actualy had sat down at one point and converted a rb20 image to hold all the maps needed to get an rb25 running but lost interest in it as at the time the pfc was the tits but has since been discontinued.

Ok, well the only wiring changes needed are if you are trying to sort out the lack of idle switch and vct control. But there are various ways to address these problems.

[jdmae86]

well I found a PWR FC for super cheap so I might be selling my RB20det ecu I just picked up. If anyone needs one so they can get the nistune stuff lmk.

[nissandrftr88]

I have a z32 ecu running my rb25 in my s14(untuned just repinned),and my friend zach had my rb20 ecu running his rb25 in his s13 before he sold it..

[Kansei240sx]

How does it run with nothing to modify the tune?

I cant remember off the top of my head, but doesnt the Z32 N/A and Z32 TT have different maf codes?

Repinned #112 and #114 which are injector 4 & 6 then added a wire to pin #37 to the maf(which i dont think mattered) and im running a z32 maf.

I know how it works, i was curious to how it runs, not how you hooked it up.

It runs fine,it runs a lil rich but i havent had time to put a wideband in it to see how rich....mainly just wanting to run rich at light throttle,but once you floor it runs great again...been driving on it for 3 months now...it's chipped and i have access to a Dyno to tune it,just to busy between 2 jobs and side work to take it

[Kansei240sx]

Did you ever run the ECU as is with no chip?

What kind of chip is it that you're using with that Z32 ecu, and is it a DE or DETT

[300Plus]

I believe that you buy the :-board(type-2)...........................................................$200.00 AUS-Rome Emulator(I have one already).........................$175.00 USD-One of the PLMS Consult cables(me usb).................$110 AUS-Individual License.....................................................$200.00 AUS

And I have found a few ecu on the internet for under $100.00 bucks.

So a total of about $685.00 you can tinker with fuel/timing and more.

I looked into all this awhile back but lost interest as well so a few probably dumb questions...

1) how do u determine what a "type 2" z32 ecu? what years do they come out of? any Maximas with them ?

2) I have Nissan Consult and cable, will this work?

3) when you say "individual license" what are you referring to?

[TSL]

1. It is an early model z32 ecu (256k rom), up to 1996 iirc. A Maxima is a different car to a Z32 300zx so no they don't come with the z32 ecu.

2. Yes.

3. The license is to unlock and use the nistune software.

Having the nistune daughterboard makes the rom emulator redundant.

So it is $510 for board, software and cable.

[tight240]

I have a couple questions concerning this, i got a little loss from people switching from z32 cpu and rb20 ecu.

1. whats needed or what pins do i need to switch to make my rb20 ecu work with a series 2 rb25?

2. i have a 90 s13, is there anyway for me to be able to get a consult cable hooked up and working?

[300Plus]

awesome I did a little reading on the Nistune board and I see its a daughter board thus like you said doesnt need the romulator. On Nistune.com it shows the same board works on the M30 which I thought was the same VG30de that was in the Maximas.

1. Not sure because the R33 RB25 S2 ECU has the igniter in the ECU, and I believe the Z32 is similar to the RB25 S1 where it uses an external igniter.

2. It should have a consult port, under the dash, near the clutch pedal is. You would need a USB or Serial to consult cable to connect to it.

No it doesn't. The ignitor is built into the coilpacks on s2.

You don't need to change any wiring to use the rb20 ecu to run an rb25.The only thing you may want to change is if you want to get the vct and idle switch working.

[tight240]

how do i get those working with the rb20 ecu???

On alot of the older models did not have a consult 2 port. It had a consult 1 port, which you really could not read any parameters of the motor. Thats why the consult 2 was brought about so they can eventually get rid of the FSM's and put it all on computer.

Cliff notes:

- Repin- Nistune + cable of your choice- Install- Dyno Tune

?

[l0nestar]

Was your S13 a KAE or KADE? KAE did not have a consult connector, but Nistune appears to work with it (use a Ver1 board, as opposed to Z32 that use ver 2)

Z32's use Consult (v 1)



Consult II is OBD II based. Not what you have.

More or less, Consult is Nissan's version of OBD 1 (early 90's - 94/95), and Consult II is for OBDII (96-2000). Then they switched to CAN-BUS in 2001.

Is that better?

The only thing you have to worry about is an ECU from a 96 Z32 - those were OBDII and were bastard cars..

[TSL]

Yep.

But just to clarify, because it has gotten confusing between the two...

- Repin for Z32 ECU (RB20 ecu does not require repin to run rb25 s1/2)- Nistune + cable of your choice- Install- Dyno Tune

I think you forgot to add '- Profit ?!?' somewhere..

but yes. that is the basic Cliff-Notes version.

Got it. So I see you were saying a repin would be needed for the RB20 ecu for "idle switch and vct control" but there are ways around it/fixes for it. What are these ways/methods?

I've never repinned an ecu and I'm very nervous to do so...

[eh?]

Yep.

But just to clarify, because it has gotten confusing between the two... (RB20 ecu does not require repin to run rb25 s1/2)

Double check your sources... swap sockets 112 and 114 if you want to use the RB20 ecu.
