Can anyone help identify this ECU?

[BAMR33]

So I took the punt on scumtree and bought an r32 ecu chipped for rb25det.

I've received the ecu and it is chipped but checking the numbers they don't line up with an rb20det ecu and the numbers on the case don't match that of the board. So here's some pictures of what I've received...

I think the outside case is r32 gt-r but I don't think that has any relevance to what's in it.

The idea was to nistune this ecu for my s1 rb25det r33 but I don't think it's going to work with this ecu unless someone knows otherwise.

Post it to Nistune - they'll soon tell you.

Google the ecu numbers mate and you will find out
Nistune is still able to install there chip aslong as they havent poured epoxy over the chip like some mines ecus
But looks ok

Looks like at r32 gtr ecu rb26

[Coullsy]

It is a R32 GTR M/T 4WD RB26DETT ecu case, but the circuitry is for an R32 GTS25 AUTO RB25DE

The 23710 number on the lid matches R32 GTR.  The MEC-R233 on the side matches either an R32 GTS25 or and R33 GTS25t (I'm not sure how that is possible, but anyway).

The MEC-R231 on the mainboard also matches an R32 GTS25.

Send it into nistune they will sort it out for you

Contacted the seller, the outside case is irrelevant just a spare cover he had laying around.

Apparently it is an r32 rb25de ecu and has been chipped to suit an r33 gts25t, which I didn't know was even possible... Just requires the wires from the third and fourth injectors to be swapped.

Has the daughter board fitted so I guess he has no reason lie. It appears to be lacking the knock board like 25t ecu so I probably won't be using the ecu anyway.

Contacted nistune, I think he thought I was a time waster lol, I do genuinely want to get nistune on an ecu. Probably just have join the nistune forum as suggested and get some more specific knowledge on the ecu...

Well, I told you it was an RB25DE ECU.....

And yes it is chipped.....but there is no daughterboard.  All I can see is an EEPROM where the original EEPROM was.

You could quite easily buy a Nistune board to install into it.  The absence of the knock board is not something I've ever thought about before, not having looked into too many NA ECUs (ie, none!), but seeing as the knock detection on these old ECUs is usually pretty shitty, most people just end up putting the same values into both the main and knock maps to stop the ECU going soft all the time.  You're not going to be horribly handicapped by it unless Nistune just refuses to play.

But here's the other side of the coin.  Surely a suitable R32 RB20DET ECU is only 3 beers and a small reptile tank swap.  Just get another one.

refund it.. useless ECU
 

Get a proper ECU or get your stock one modified to accept a Nistune board. I can get it done cheaper than RRP or supply you the board to solder yourself - however I suggest the soldering done by Nistune themselves as the can bench test the ECU prior shipping it back.

I wasn't doubting your advice, I also come up with the same result of rb25e before posting this thread, I just wanted opinions without my bias added. I used the wrong terminology when I said daughter board before, I thought that was the cradle thing where the chip sits which definitely has installed.

RB20det ecu's are priced like they are gold plated because as you probably know you can't chip the r33 rb25det ecu's and have to use either rb20det or z32 ecu so demand and price has gone up. These ecu's go for about 250 second hand on eBay out of Japan, 25 years old plus and could be stuffed and then you have fit nistune on top of that which starts to get into the power fc price point. That is I why I bought this ecu, I thought I was getting a bargin but poor man pays twice I guess.

[BAMR33]

So it has the socket soldered in, that's what I meant when I incorrectly said daughter board.

[GTSBoy]

Yuh, I still reckon you could Nistune it.  It's the same basic type as the RB20 ECUs.

[Dose Pipe Sutututu]

I can supply Nistune boards cheaper than RRP. 

[chiksluvit]

Ordered mine from Dosey, good service too! had it sent back to me within a couple of days plus got a map uploaded and settings preset so I could pretty much fire my car up straight after install!

Thanks for the offer mate, so do you know for sure if this ecu will work or not? And do you sell the cable and licence?

[Dose Pipe Sutututu]

yep.. but I don't get discounts on them.. will just sell as Nistune sells RRP... but you save on shipping if combine...

ECU.. no idea.. needs to be powered up.. can't just use the Internet to tell you if it works or not haha
