I'm out... that has way too much nonsense to continue. All the best man.

Oh my god, I'd heard about this thread and for some reason decided to have a look.   Kudos to the people who have tried to help, @Slap... I say this not to be a hater, but to try and help you.   You r

Got it all sorted.. shop over here verified the base timing then set cam timing, also lowered the idle so now it's at 650rpm with no issues. Gives me peace of mind.

I will now quote myself.
And thus, yes it is idling.  It is not running on the main maps.
And the original argument was whether the ECU added 15° to a static 15° for a total advance of 30°BTDC, which is not the same thing as the ECU using delta control to manipulate the idle speed.

Sounds like the reading is actually the Timming added by the ecu. Wich would suggest to much manual advance on the cas.
I believe the ecu normaly adds 10 -15 at idle so it stays at about 30 on idle.... according to my rb25 experiences.

A slight rough idle can happen from an exhaust leak prior exhaust o2 sensor.
The standard ecu on an rb always hunts for the best spot. The more air tight and fresh your plant the less noticeable the hunting.

I would try retarding the car 5-12

      Short shifter r34

      By PLYNX · Posted

      Don't do it if your gearbox box has already having syncro issues. The short hifter will put a greater load on them. If you must I remember Nismo did a shorter shifter, with the top part being physically shorter and the part that went into the gearbox was the same as stock. In saying that I've had a C's short shifter (I think) in mine for many years, which was given to me as the previous owner was not sympathetic to the gearbox. Thus forwarned I was careful and had to modify my normal changing style. You have to be super accurate with your clutch and shifts

      R32 Sedan - Grip and Drift (have my cake and eat it too build)

      Well, after a week of daily driving and having to crawl out between the wheel and the side intrusion bars. I got myself a quick release setup. I went with an NRG short hub and Quick Release with some cute heart cutouts on the pull tabs. Nice and matchy matchy with the rest of the interior accents I have going on.  The only downside is the total stack height even with the short adapter is longer than the old HKB boss kit. Luckily I had some adjustment left on the column so move the wheel away.

      stock shifter with new bushes, springs and cup will improve it. Gktech do all the bits. The opinion as the years have gone on is the redline is not great in old gearboxes.

      Hi all   what short shifter do you use on your skykine r34?   my synchronous does have a problem and i was getting huge delay and grinding sound between 2nd and 3rd, did put shockproof red heavy stuff and it is great now/ no issues   would in your view short shifter screw this up?   people seems to suggest/ use cube short shifter and there is standard and premium. Seen review of premium as much better and less play. Thoughts?

      R34 oil and timing belt change

      By GTSBoy · Posted

      Yeah, there's a bit of a density and friability difference between pebbles and any of those other things. Silicone will definitely float in oil and so will be mobile enough to move around. Although, again, if it is upstream of the filter it really shouldn't go any further. I would only ever worry about silicone when it is in places downstream of the filter. Upstream of the pickup is a whole 'nother matter. We've all seen what that does. I have seen the most abominable crap settled out in industrial gearboxes, trunnion lube systems and the like, without any sign that any of it has touched anything in the machine. Just chilling in the bottom, waiting for the inevitable operator error that causes the whole machine to need to be dismantled for repairs.
