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.

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.

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

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      R32 GTS (RB20DE) Injectors Replacement

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
