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
When i said this

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.

    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
    • Yeah, shame. Maybe  driver's carpet is available 🙏. I am waiting for both amayama and nangun to confirm.
