Guys - Major break through. Went back to my car dealer as Nissan was hesitant in diagnosing the car. They have very little knowledge about cars in my opinion. If the service manual doesn't state it, t

BIG DRAMA

Car was booked in at NISSAN by cardealer where i bought car from,When i got there at NISSAN dealership the guy who is working on my car said he is keep sending request to Nissan to get software update but frm japan they are not releasing.Now he said to wait till monday to hear from them they have requestd again.Otherwise they have got the part no which is brand new ICU,they wll have to buy.Cz cleaning throttle body has caused trouble to car which is wen dey start the car its playing up with RPM,it keeps playing between 1100-1900 range its not stable

any advise what to do ???

I have asked for a refund for my car but manager says plz give us time to sort this out.

Cleaning the throttle is something most Nissan mechs know not to do.

There are plenty of throttle relearn procedures they can do in the consult 3 diagnostic program, but I think they need to be done in a certain order.

I had issues when I did a TB clean. My rpm fluctuated fro 1.5-2.5k rpm non stop...I went as far as getting new TBs but still same issue. Not too sure what the issue was there. Nissan couldn't figure it out. They did ECU reset, reflash, throttle relearn and whatever other relearn/reflash/reset possible. Nothing worked. I ended up taking one of my mates TB, same part number everything but that worked on my car...so we just swapped.

That is my next step if I can't get the file. Buying a new one already updated.

I think dats what they will have to do as well for my car,cz if u cudnt get update from Infiniti Australia.There is no way they can get here as well.They might endup buyin another ECU used one or may be brand new.Looking forward to get my car back its been two weeks now.hopefully good news gona come towards coming monday fingers crossed ....

I tried finding a second hand one, but could not get confirmation from anyone if they were updated or not.
Not sure of the price of a new ECU (wouldn't be cheap) compared to a second hand one (see them on ebay around the $300-$500 mark sometimes)

Hello All

Just an update on this dealer bought second hand ECU to fix my car which arrived last weekend.Nissan was hoping by replacing it problem will go away.But today i got an update throttle body and ecu codes doesn't match.So they need two brand new throttle bodies and brand new ecu.

Anyone knows will this work or not ????

And the idle relearn procedures aren't working? There are 3 processes that need to be followed in order to get the idle to relearn. If it doesn't find 650rpm + or - 100revs it won't set, in which case you most probably have a vacuum leak.

If the process works, and the idle drops, but then goes back to a high idle after you restart the engine next, you probably have an engine fault code logged in the ecu.

The rough idle, what makes it rough? Does it sound like it has lumpy cams? Is it missfiring?

      Why am I hitting a power wall with my stroked RB25?

      By Dose Pipe Sutututu · Posted

      Given you're running a 2.8 and my 2.5 is not really like for like, I suspect there could be a bit more timing you could give it. What is the kW yield per degree you're putting through it? Here's my E85 map to give you an idea, where it was I could still get another 3~4kW per degree thrown at it.

      Mistakes were made, my R34 Story

      It turns out that Setrab make a fan specifically for the oil cooler which is great and I've installed it with minimal swearing. I removed my 2x 12in push fans from the front of my aircon condenser and wired them into this. My main thermo fans kick on when I use the aircon anyway and would effectively already be working as puller fans through the condensor which is infront of the rad. The push fans (understandably) didn't really do much in the config they were previously in so now they're out. Now we're on to the "Oil fan doesn't really do much either!". Yes I'll duct it next if it does nothing in heavy use which it shouldn't. But hey, the object exists and fits great and is cool. Let me have this. The car is still in the "do my fittings leak oil now? do my wheels actually rub?" phase. I did a spirited drive on them and didn't hear or feel anything. Then I got back home and noticed there were grind marks on the inside of the rims, though I couldn't see where they were touching I got out the grinder and attacked the suspects. Note: I do not know how to use a grinder. Then I realised I had dragged my new rims across my concrete driveway before I did this drive. I didn't think I had damage at that time when I briefly looked...... but remembered this occurred after I did all the angle grinding. The grinding on the wheels in some very specific spots. It's not around the whole rim for example, which lines up with dragging it across concrete more than hitting a suspension component for even 1 full rotation. So everything is currently painted and taped up and I need to test it some more to see if it really IS rubbing, but from inside the car it doesn't feel like it is. In other news I attempted to do a before and after comparison of the heads/cam upgrade thing. Dynos lie, everything is in different measurements. Here is the data from the sandown back straight. Car go faster than before. Vroom vroom.

      Here's my base ignition. +3 correction to redline when shooting water/meth which is always on. Looking at my old ignition table, I should be able to add 1-2 degree's next time I'm on the dyno.  Let me know your thoughts.

      Given what I know now - same haha, but this was 12 years ago with second hand 740cc Nismo injectors in my S15 daily, I was too busy hunting elsewhere for the issue to even look at the injectors, running through some cleaner was a happy coincidence haha

      Not a terrible idea. But if I ever had concerns that my injectors were sufficiently dirty to be causing me a problem, they would be out of the engine and onto the actual injector cleaner/testing bench.
