Hi All,

poking around with the car I found few ecus and appreciate if someone can tell me which one is what .

pics below

also my ecu looks like it had some wire cuts , I am thinking the previous owner may have changed it to those boards that still use same shell with different board.

is there a way to find out without opening it?

does the dignostic software tell you ?

1.in the boot passenger side( is it hicas?)

2.boot driver side (hicas or abs ?)

3.under passenger footwell ( ecu )? look at the tampered wires suggesting cutting was done

4.under driver side footwell close to the gas pedal , what is it ?

5.under drive side footwell close to clutch

So, so googleable. Just for you own interest, why don't you try to google an image of a Nissan ECU? Google an image of a a HICAS CU.

And here's a tip. The E in ECU stands for Engine. So there is no such thing as an ABS ECU. It's just a CU.

I'll give you one hot tip. The numbers on those boxes are also googleable.

And here's a red hot tip. A screwdriver gets you inside the ECU too, so that you can answer your own question.

That was very sarcastic!!

I know what ecu is but not which one is what

Fair enough you can take the e our and say computer unit etc but generally people do say it is x ecu y ecu

Anyway , i will google and if anyone isn't as sarcastic and helpful of gtsboy then reply ( if i dont myself after googling model number)

I know and the box doesnt say on the label

You have the fuse which i know ,duh

You have relays which again is straigh forward but then you have the yellow green pink ones right at the top which have no clue what it is as never have seen such thing in 15 years of working with cars

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
