Hello everyone 

Ive got Skyline v36 350GT 2007 

car starts hunting on idle 1500-2200 rpm) after cleaning the throttle bodies 

Ive taken it to a specialist here in Perth and they told me they have to take the tbs out and reset them manually and they did, nothing changed still hunting 

They tried everything nothing worked yet, they finally said the ecu needs to be reflushed but they don’t have the software for this model neither Nissan dealer.

any ideas or anyone had same issues 

 

cheers

The good people at Uprev have the re-learning procedure here: https://uprev.com/documentation/Resets-for-Nissan-Infiniti-Functions.pdf

Super fiddly, but my car would barely run after a reflash until I got this right and is now perfect.

Note, disconnecting the battery for a minute or 2 is worth trying first

I believe the alternative is to do it via a consult, so you may have to try nissan, they are incorrect if they think they can't do it, the just need to choose DOM for Japanese Domestic on the Consult.

The key procedure is painful to get right...

One other option, does it idle OK if you unplug the AFMs? I had an AFM die which sent the ECU to limp mode, which allows it to run fine at idle (but not rev)

Duncan

Nissan said they don’t have the software for this model(2006-2007) which is ridiculous

hunting go away only when you disconnect one tb and leave the other one connected 

other mechanic suggested to put a 370z ecu don’t know how accurate that is 

Interesting, and what if you swap the TB, does the problem follow the TB or stay with the wiring?

Nissan are just choosing not to help (or don't know their own software). The software is the same across all models including JDM, perhaps consider another dealer if possible.

I have a consult clone, as Duncan said, you need to change the region to DOM.  If they leave it set to Oceania, they won't get the option to select this model.

Sounds exactly like the symptoms you get when you mess with the throttle bodies without doing an idle air volume learn.  Very difficult to do it via the manual method.  Consult or nissandatascan will do it.

Mechanic sounds like they are spitballing..

I get nissan are choosing not to help, or don't know they can, but the hardware/software local dealers have do have this capability. Like Greg I have a consult III clone which can connect to my fuga and other weird imports including my Cima, Titan etc OK.

yeah, consult is the nissan tool that all dealers have, you can buy Chinese clones of this which do the same thing.  There are other options out there beside Consult (can't say I have heard of anyone using the term 'consult' for devices other than the Nissan devices).

I know the nissandatascan software can do the idle air volume learn among other things the basic OBDII tools cannot, but they are not on the same level as Consult.

You need to buy your own adaptor though, their webpage lists compatible adaptors.

You would need NDSIII for the V36

Not sure whether this is related: Motorvate DIY has this warning on his idle relearn procedure for the Infiniti G37

*** NOTE: If you have a 2007 G35 or 350z (engine: VQ35HR) there have been reports of an ECU update that is required to allow the idle air volume learning to work. Without the update, after cleaning the throttle you will have a high and unstable idle ***

I was experiencing the same issue after cleaning my throttle bodies for the first time after 85,000miles on my 2007 sedan. The car would not let me relearn the idle, no matter how perfectly I timed it, even using the NDS3 app it didn't work. I took it to my local Nissan dealer and told them to flash my ECU to version C and then perform the idle relearn. It worked! Car drives perfectly now.

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
