Taking foot off peddle and reapplying thing....that might be another issue altogether. I believe that is the drive by wire issue. When we step on the accelerator, the ECU tellls the TB to open...when

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.

hey scotty car was at dealer's mechanic first he tried to solve that problem so he did cleaning,when it got out of his hands he gave up and reffred to Nissan and he has made that problem even worse before i could drive my car,Now i can't even drive.Sick of this LOAN car they hve given me ,Hopefully something will workout my way coming week

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?

      From my youth: GTi-R clutch change is a massive pain. The gearboxes are fragile? But the car is super cool and I want one 😢

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)
