Hello all, my first post here. I searched my questions for a few hours, Im hoping this isnt going to be repetative, I tried my best to make sure it isnt. I have a few questions in regards to the ECU's (ECCS) found in 89-90 model year R32 GTS-T and GTR's.

First question, I have learned there are 3 types of computers found in Skyline's. I was wondering which of the 3 are in the models I mentioned? The 3 I have read about are as follows: First type has two LEDs and five modes, second type has one LED and two modes and the thrid type has no LEDs, the output is done with the engine check light in the instrument cluster acting as a single LED ECU.

For the two turbo R32's, what sort of standalone systems are out there that offer relative ease of use. As plug-in play as possible. I know this has been discussed before, but Im still a bit lost. Does Apexi make a PFC, or can one from another engine be adapted? How programmable is the factory ECU? At what levels of power and modifications should a standalone be considered for the RB20DET?

My next question, how difficult is it to find a good used (or new if I can get it still) Electronic System Diagnosis Tester, in English if possible. I noticed there is a number in the R32 GTR service manual, EG1180-0000, would this be a Nissan part number? Is this devise compatiable with all RB ECCS's? And lastly, anybody have a clue roughly what this would cost new and or used?

My last question is in regards to the ATTESA and HICAS control moduals. I have yet to find this in the manual, but does anybody know the pin out wiring diagrams for these two?

Thank you much for any help!!

At what levels of power and modifications should a standalone be considered
When your budget allows for it basically. The factory maps can nearly always be improved upon by an experienced tuner - every car of the same type leaves the factory with identical ECU maps, but each will have slightly different engine characteristics. This'll be exaggerated even more when you start doing exhausts/pods/boost or more, which takes the engine further and further from what the ECU was originally programmed for.

In a nutshell: You will more than likely gain power from a programmable ECU even in a stock car, particularly earlier models, but they really come into their own once you've started modifying.

R32 ECU is reprogrammable, but by the sounds there wouldnt be too many workshops that know how to do this?

There is a power fc for R32 plugs straight in and comes preloaded with a base map so you can start and run the car without dramas.

The only Nissan consult I have seen cost the guy around $7K AUD second hand, so he told me.

      Strange issue RB25DET wont start

      By jtha7 · Posted

      Ps i found the below forum and it seems to be the same scenario Im dealing with. Going to check my ECU coolant temp wire tomorrow    From NICOclub forum: s1 RB25det flooding at start up Thu Apr 11, 2013 7:23 am I am completely lost on this. Car ran perfectly fine when I parked it at the end of the year. I took the engine out and painted the engine bay, and put a fuel cell with an inline walbro 255 instead of the in tank unit I had last year. After reinstalling everything, the engine floods when the fuel pump primes. if i pull the fuel pump fuse it'll start, and as soon as I put the fuse back in it starts running ridiculously rich. I checked the tps voltage, and its fine. Cleaned the maf as it had some dust from sitting on a shelf all winter, fuel pressure is correct while running, but wont fire until there is less than 5psi in the lines. The fuel lines are run correctly. I have found a few threads with the same problem but no actual explanation of what fixed it, the threads just ended. Any help would be appreciated.

I found the problem though. There was a break in one of the ecu coolant temp sensor wires. Once it was repaired it fired right up with no problems. I would have never thought a non working coolant temp sensor would have caused such an issue.

      Hi sorry late reply I didnt get a chance to take any pics (my mechanics on the other side of the city) but the plugs were fouled from being too rich. I noticed the MAF wasn't genuine, so I replaced it with a genuine green label unit. I also swapped in a different ignitor, but the issue remains. I've narrowed it down a bit now: - If I unplug and reconnect the fuel lines and install fresh spark plugs, the car starts right up and runs perfectly. Took it around the block with no issues - As soon as I shut it off and try to restart, it won't start again - Fuel pressure while cranking is steady around 40 psi, injectors have good spray, return line is clear, and the FPR vacuum is working. It just seems like it's getting flooded after the first start I unplugged coolant sensors to see if its related to ECU flooding but that didnt make a difference. Im thinking its related to this because this issue only started happening after fixing coolant leaks and replacing the bottom part of the stock manifolds coolant pipe. My mechanic took off the inlet to get to get to do these repairs. My mechanics actually just an old mate who's retired now so ill be taking it to a different mechanic who i know has exp with RBs to see if they find anything. If you have any ideas please send em lll give it a try. Ive tried other things like swapping the injectors, fuel rail, different fuel pressure regs, different ignitor, spark plugs, comp test and MAF but the same issue persists.

      Freddy Plenum vs Genuine options RB25

      My return flow is custom and puts the return behind the reo, instead of at the bottom. All my core is in the air flow, rather than losing some of it up behind the reo. I realise that the core really acts more as a spiky heatsink than as a constant rate heat exchanger, and that therefore size is important.... but mine fits everything I needed and wanted without having to cut anything, and that's worth something too. And there won't be a hot patch of core up behind the reo after every hit, releasing heat back into the intake air.

      There is a really fun solution to this problem, buy a Haltech (or ECU of your choice) and put the MAF in the bin.  I'm assuming your going to want more power in future, so you'll need to get the ECU at some stage. I'd put the new MAF money towards the new ECU.
