fast shows that p/n 23740 0V310, as being an ecu out of a 08/97 to 08/98 stagea which puts it as a S1 ecu

here is a fast screenshot:

and here is a fast search of you ecu number, 23710 0v801 but look like you could use a 23710 0v800 with out a problem.

I concur - the 0V310 is an auto trans ECU.

bad news, you have the same bastard child stagea ECU that I had. the lovely people at nissan jp created an ecu and wiring loom for only a single month of production which was different to every other one.

what do you need to do? no other ecu will work unless you modify it to suit...i've been through all this including a burnt out PFC (injector driver issues)

[lachlanw]

thank you very much qwk32 . come collect your reward any time you are in chch nz

[lachlanw]

cheers duncan . can you tell me what else you know about the bastard child ? pm if you want . my intentions were to get the ecu for sale re mapped by nzefi in christchurch nz as they can re map r34 gtt ecus and have done stagea ones but they said theyd need to check it out first , and keep my standard one spare .

do you agree with qwk32 i could use an 0V801 in place of mine or is that what you were talking about saying it needs to be modified ?

[QWK32]

i think duncan misunderstood your post a little in thinking your ecu is the 23740 0V310. the ecu the guy is trying to sell you was only in a short run of S1 stagea's, and that it has a completely different pinout configuration than the other S1 stagea ecu's, i think i'm right in saying that there were 3 different S1 ecu's, duncan? and each of them had a different pinout configuration.

but thats really got nothing to do with what your after lachlan. you need a S2 ecu, a S1 ecu wouldn't work and aren't easily chipped like the S2 ones are. the 2 ecu's you could use are the last 2 p/n's on the bottom of the second pic i posted, the 23710 0v801 and the 23710 0v800, as they are both S2 manual ecu's. though one thing you may want to look into is using a R34 GTT ecu, its the same engine. 4WD compatibility shouldn't be a problem and you don't have the auto shift logic to worry about.

oh k cheers for that . yeah i had a gtt one lined up aswell . this one popped up on $1 reserve and he says its a manual neo stagea one . its like frukin jack pot but yeah not happenin . cheers heaps guys . will get a pfc later on when i get new turbo and everything else

[Duncan]

ahh yeah sorry I had it all backwards. no-one wants that ecu and its worth about half what they are asking....

[Brad_00]

I'm hoping someone in here could help me? I have a 2000 RSV AT stagea with a ecu part number 23740 0V801 that I think is stuffed and i need a replacement ASAP.

If someone could tell me if there is an alternative part number or someone has one for sale, please let me know.

Cheers,

Hmm lol while were at it

My s2. Auto.... Now manual... Can use both auto and manual s2 ecus now?

There's an as new R34 G4 Link for sale on SDU for $1500 which is a decent saving. EFI can install and tune.

definately OK to use an auto ECU in a manual stagea

[chef_stagea]

i have a guy keen to buy my nisstuned ecu (rs4 auto...also fine for manual)

but he wants to swap with an RS ecu... this is no good for either of us is it?

answer being no... any one eles keen??

i get that auto ecu runs manual and auto car.... but will manual run auto and manual car? silly question maybe.. but dont want to swap and have issues

[QWK32]

a manual ecu wont have the A/T controls in it. so no, a manual ecu wont run an auto

[chef_stagea]

How about the rs - rs4?

[Race__24]

I'm pretty sure the AT ECU is a separate beast all together, located behind the drivers side kick panel. The only thing that you will loose is possibly the ignition retard on gear changes which isn't a problem if you have a good shift kit in there

[Race__24]

I can't say for sure if it will work or not but if it can go one way you would think it would go back and Atleast run the engine. The only other thing I can think would be a problem is the neutral switch. Could be nasty having the car start in gear

[QWK32]

On the S2 (NEO motor) the auto shift logic chip is apart if the engine ecu.

Chef, as far as using a RS ecu it will run the engine fine, and i guess the auto too. only difference being the RWD stagea's have traction control. You may have to do the resistor trick to disable the TCS and stop it throwing up error codes.
