Rom Tune A Rb25 Neo With Z32 Ecu

[Lopin18]

Ive searched all day but i always find nistune boards being used. Im from a caribbean island and getting my hands on nistune is hard.

Im changing from a ka24e turboed and chip tuned on a stanza ecu using eprom emulators. So i know my share of rom tuning

Now the question is apart from nistune. Is the z32 ecu capable of being rom tuned using a rom emulator after being wired correctly? I have access to the nistune application but not the boards. So my only option is using nistune's app and a eprom emulator to change the values and burn a chip etc..

Links to wiring info or related info would be appreciated but ive found a good amount on info but all related to z32+nistune boards

Just buy a Nistune board from Nistune and pay the freight. Done?

Will do if i ever can. But my budget is very small. I got the engine through a friend financing it to me. But so far all the budget will go into mounting it on my car. Im just trying to find alternatives. And yeah im not kidding. 500us right now isnt available to me any time soon.

The obvious thought is that if you can't afford the engine, you definitely can't afford to modify it......

[Lopin18]

Hmmm indeed, but this is a 6 month engine project as the drifting season is off right now here so its covered. Im just trying to find an alternative for the tuning part which is the one not defined on the plan. If its doable ill try it, if not ill have to delay and get nistune in the end, but if possible id like to try out the z32 option. Sadly as you guys noted, Nistune is the way to go, and seems like very few people have tried the other way.

Mate buy a power fc and save yourself some time and lastly money. As I value time over money. A power fc did wounders on my gtt r34.

[WMDC35]

there are better options but you could run the 25 with the z32 ecu tuned with emulator

[Marcus89]

Why run a neo on z32 ECU?

[Lopin18]

Supposedly the Z32 can manage the VTC of the Neo, Its a 8 Bit ecu so you can chip it and run a rom tune.... or so goes the idea. Also people usually get that one to run Nistune.

Ill just test using the Z32 with the local tuner, if things get complicated ill just delay the project and get Nistune for the Z32 ecu and RB25, but i have to inquiry now if i should use the Type 4 board on the stagea ECU, or the Type 2 board on the Z32 ecu. But ill go to the nistune boards for that one.

[Guilt-Toy]

yes. the z32 ecu can be tuned with a emulator. i was just emulating one 10 minutes ago.

use the file

Z32_FOR_RB25_41P03_MT_v2

in the nistune rom pack in the type 2 folder

but how are you going to plug the z32 ecu into the neo loom? are you going to re-wire the ecu completly ?

let me know if you need any help.. ive done quite a few of these.

This is true but most people do that for normal rb25's as there isn't a nistune chip to suit the rb's from r33's. There's a nistune chip that installs directly into the nistune computers though

Use the Neo or Stagea ecu - it will run the vct for you - as Marcus was saying people only use Z32 ecus on R33s because there is no Nistune for R33

After many months reading diagrams, confirming ecu pinouts, cutting and soldering wires, i finally completed all mechanical work today got to test my Z32 adapted wiring, after changing the fuel pump relay it was an instant start.

I had a Stagea RB25 Neo, with its wiring loom and i used that one. I cut the stagea plug and rewired the ecu plug to the R33 plug & pinout, almost all important wires have the same name in the R33 just different positions. Then i changed the R33 pinout to Z32 pinout, which had minimal changes in positions, switched the CAS wires to the new layout that the Z32 uses and followed Nistune's guide to prepare a Z32 ecu to work with the R33 rb25. Worked the usual ign 12v+ wires, battery 12v+, grounds, etc and that was it.

Currently running the Z32 ecu with a Moates Ostrich 2 with the file mentioned by GuiltyToy "Z32_FOR_RB25_41P03_MT_v3". Now to put everything in its permanent position and tune it.

Its a cheap way to do it, but it was interesting and i learned a lot. Its an option for those who cant go the full mile.

Well done!

[Guilt-Toy]

f**k yeah!!! well done mate!

thats an awefull alot of trouble to go through for just a eprom z32 ecu when you could have just nistuned your ecu for about $200

there are plenty of ways to shoot yourself in the foot

wouldnt mind seeing some pictures of the wiring job and of the car... very interested.

[Lopin18]

Yeah i know, but ive always liked trying things out and since i had some months free until the engine's swap work would be completed i took this option. Also many RBs here in my country are using Z32 (many of them dying for some reason unknown, probably our horrible gas or something being wrong with their z32 setup) since this is a third world country i knew that if i made it work i could help others here.

Soooo this is pretty preliminary, ill attach what i used to understand and do the wiring, dont take it as a 100% guide since after i printed these pages i did the wiring, they are all marked and dirty etc but ill be busy for some time now that the engine is on and i have to test and check everything, someday ill make a nice guide confirming everything if needed (i know the pinout references are ok, but the power lines and ground lines you have to think about them):

- These two pages are the resume of what i did on the pinouts, one says which pins came from the stagea plug and where they went in the R33 plug, the other page then says from the R33 to the Z32:

Edit: I think there were some pins i didnt write.... confirm all pins with the Pinouts below.

And these ones are that i used to make the pages back there, ugly as hell but oh well, the original diagrams are around found in google very easily.

There are many pins i didnt use, this is a drifting car so i ignored a lot of stuff from Air conditioner etc

This pinout shows on pencil where each pin goes to in the R33 plug, affirmative marks just mean its the same pin in the r33

Z32 pinout, says on pencil which pin from R33 goes into each pin

And finally the Stagea wiring diagram, i marked in yellow the wiring to be done outside of the plug, which are all the 12v positive wires and grounds, so i could make sure i had power everywhere and ground just as the diagram says for any future troubleshooting.

And for consolation, i didnt study wiring etc, i once checked my KA24 wiring with the FSM and decided to shorten it and check all wiring, then i took this stagea thing into my hands, so not a wizard here, i learned by logic and by reading the diagrams and seeing the wiring loom in person along with a tester to see which plug, line, pin etc went to and came from.

lol.. love the piston and spark plug pics......

what country are you in ?

[Lopin18]

Yea that was my poor ka24. Sleeves installed and died in the first 3 runs bah....

Dominican Republic.

Ahh yes Consult isnt working tried everything switched pins rechecked. Nothing. Great

[Lopin18]

Just for the record, Fixed the consult. It was a cut track on the board damaged from the rom chip work. Every is working perfectly now.

Well done! I'd say you could get plenty of work in Aus or NZ sorting out people's wiring.
