It does say on the specs that the N1 is disabled for KBM50AA. I was told its a different part for N1 ecus, its possible yours has been spec'd for the N1 ecu.

Im sure it a address issue.

i believe they use something similar to s15 board - but i dont know what exactly.


That board is an S15 board, they're the same board. The 8 injectors is really nothing to do with the board, its to do with the programming/rom that runs on the board as the board only interfaces with the CPU, it doesn't actaully drive the injectors.

What board did bazza1600 use on his N1 over there? I'm *sure* its the same daughterboard ??

I will look into this more looking at diagrams of the two eucs for comparison but there will be the small issue that the N1 diagram is in Japanese.

They can tune the De ecus just perfect over here. The country is full on high hp nissan drift cars. I never said that they couldn’t tune them.

It’s the Ve ecus equipped with a daughterboard I am talking about. And for whatever reason these are not as simple to tune with the nistune software.

I understand that you can just get a DE ecu with a board, a vvl controller and tune away but this a slightly different situation.

I have searched this forum and various other forums and only put up this thread afterwards.


My apologies for sounding like a total dick head, or bell end or whatever you guys call it I read my posts later and am sort of shocked at how they read back.

What exactly is so different about the N1 that it needs a different ECU? probably centered around injectors, since it has 8. Possibly different resistance, such as in the GTI-R motors? if it is that much of an issue, I would just go standalone anyway, far superior to any daughterboard setup.

No worries will .

I don't know the differences electronically honestly except that it runs the 8 injectors and the flap on the intake pipe.

I agree that standalone would be best but cost etc plus already have the board installed.

As far as I am aware thats the db thats in all the chipped ecu's over here. I
checked and thats defiantly the one in mine.

What boards are used to tune ve ecus in New Zealand or have you different type ecus to the normal sr16ve's we imported over here Evlnxr?

Here is a picture I copied form another n1 build over here but mine looks the exact same, I checked tonight.




The 8 things LOL on the top left are for the injectors from what i'm told.

What information would I need to get to help you help me LOL?

Its the same board and yes those are the injectors drivers.

The only thing i don't know (as i haven't done it) is the installation of the board normally requires a lot of resistors to be removed/changed/added in various locations on the board. I don't know if the N1 ECU is the same in that way too or not as i never pulled the ECU out of my N1 when i had it and those who have N1 modified ECUs don't seem to openly post that kind of information (for obvious reasons).

I say just ditch the extra injectors and run a standard ECU. Our daughterboard setups are the same as that one. One Issue is that later model OBDII ECUs (at least the the US) are much more complicated to tune.

There will be new Realtime Tunable ECUs available from a vendor on this forum soon, I see no reason they would not work on an n1 (other than the injector issue)

Speak to POC, he's in meath I think
He's your Irish contact to bill in Greece... considering cost, this is your best option. Uses the n1 standard ecu with a custom nistune board

I would recommend LINK though. Gtir plug and play board.. can run 8 injectors. More expensive but very much worth it

Custom nistune board ?

What ?

The new B14 boards won't work on the N1. N1's are still OBD I. I have spoken with Dave from tunercode, developing a VE board is 'on the cards' but is not a priority as Tunercode for B13 (and soon B14) does everything most people need with the reallocation of existing outputs, and is more compatible for existing USA owners.

ok, so run an OBDI board? I don't see what the issue is? OBDI is much easier to work with. You have the later style harness plug? just get a step down harness. The only drawback I see is the loss of 8 injectors, correct?

If it was "that easy" people would be doing it already.

The VE ECUs are uniquely complicated in their design and interface that's why there are less than a handful of companies or people that did/have/do make a board for them. The market is so small, that the devlopment tech time to make a board is really not worth it, which is why nistune don't already have a board for it. The board pictured above is, at the moment, the best & most cost effective board if you need to keep the existing hardware setup.

The N1 ECU plug is very similar to a regular B13 OBDI, but its slightly different so you can't just run a conversion harness, not to mention the wiring in the harness is totally different so a conversion plug (if you could find the right plug to go between) would be a *real* pain to do.
