Dayuum... has anyone tried this on an r33 yet? it's right under the inlet manifold! basically need to take the whole inlet off to even see it! this will be a bastage of a job...

Hence my tut and pics to show where it is. It took me forever to work out what it was based on people's description! haha

I dont think you need to take the whole inlet manifold off. I was trying to get to mine coz i have a high idle problem. If you take the oil filter off it will give you a bit more room.

I just did an oil and filter change so the air regulator is going to have to wait

yeah it's actually in a different spot again... the biggest thing for me was knowing what the damn thing looked like! but yeah descriptions alone just dont cut it! below that WHAT, exactly? :P

good work mate

Inasnt you're right removing the oil filter will free up a bit more room, still think it'll be a caaaaan't all the same. I'm in the same boat as you, just did the oil change. it's just a right piss off! the other day my damn car stalled because of it... and I hate hearing that pinging when it pulls itself back up off 100rpm! think i'm just gonna have to skin some knuckles...

This was an absolute pain in the ass to do, had to open up the air reg while inside the car coz the harness would just not come out. But I am so happy after checking AFM, throttle body, TPS, cleaning AAC this finally semi-fixed my idle.

It has however mostly fixed my idle, I'd like to know whether inside of it the opening is meant to be over the hole at all. In the picture posted it looks like there is still a slight gap(about 1mm), and that is the same with mine, however I would have thought it should be fully closed. The idle has dropped down now(but now its almost stalling coz it drops well under 500 after reving then flicks back up), but I wanna know whether i will need to buy another air regulator to adjust it all properly.

btw I couldn't find a spring to buy that was small enough anyway.

Cheers,

Adrian

I will be trying this tonight...Does anyone have any pics specific for R33?

I had a look last night to see if I could find it based on this thread, with no luck.

I might take the plenum off to make things easier.

I took mine out and gave it a clean however I noticed that the spring was not holding the bimetallic plate on fully, allowing air to escape on idle (causing idle to stay around 1500-2000 depending on temp)

I got a quote from Nissan, $276.95 for a new valve. I will give this a go and report back. Hopefully the idle will drop back down to normal.

For an R32 RB20 you don't need to remove half the stuff listed. I just pulled off one side of the 2 small vacuum lines and the larger lines with the T-piece. The only tricky bit is working around the loom which runs over the top over the unit. Oh and dropping the bolts down into the manifold :).

Hence me saying...

"2) Have a look, and work out if you can get to it as is. I couldn’t; so I chose to remove the following, you can skip ahead if you think you can get to it without removing them."

      ECU sees many times the speed than speedo does (R34 swap)

      By Kapr · Posted

      The car/ECU will have all the sensor that it needs and expect to have. I think i do not have to explain to you how the Link is way better specialy if you have swapped engine   I just do not want to deal with any "problems" cuz i have only Nistune which i learned is not that great and in my case cant even deal with that speed problem (Link can) And of course it will be way more easier to tune and diagnose and safe. And for the ECU/speed problem...i dont know.

      Per Mark Roberts of Sonictune: Mark Robert Author At this time, no. No ETA either 2016-17 models. You will be able to purchase and install a 2018.5+ TCU though   TCU purchasing and pricing info! As we near the release of TCU tuning, I am going to answer some questions I get asked often.   What do I need for TCU tuning? At this time, you will need a 2018.5+ TCU to be able to tune. If you have a 2016-to early 2018, you will need to replace your TCU with the newer version. One good way to know if your TCU is good is if you have auto upshift in manual mode in 1st gear around 6500 rpms. If your manual 1st gear goes to 7k rpm and will hit the rev limiter unless you shift, you have the older TCU.   Why do I need to buy another ecu license/phone flash if I already have it on my ECU tune? The TCU is its own computer module. It is completely separate from the ECU. Because of this, you will be required to purchase a TCU license and, if your tuner has it, the phone flash license required to tune it via phone/bluetooth.   Do I need TCU tuning? TCU tuning is NOT required. However, the faster your setup, the more it will assist in track and dragy time consistency.   If I’m ECU tuned by (tuner A) can I get my TCU tuned by (Tuner ? Yes, since it’s a different module and a completely separate flash, you can have two different tuners. However, it is highly recommend that you have both tuned by the same tuner. For me, my TCU tuning will directly complement my ECU tuning style and features and running my ECU and another TCU or vice versa MIGHT cause some issues. At this time and for the foreseeable future, I will only be tuning my current ECU tuned customers TCUs.     I have a SYVECS AWD controller. Do I still need it? Yes! The AWD controllers main job is to control your AWD system. However, with TCU tuning, you will no longer need the auto-shift function as that will be done through the TCU. The AWD controller will still be very beneficial for racers looking to maximize traction on the launch.     Shift schedule changes: holding gears longer at lower pedal input as well as max shift rpm changes. Please note, the new ECU race rom coming out will address 90% of the shitty drivability issues these cars have through custom maps from myself and Racebox—as well as others I am sure.   Increase shift speeds: as seen in the videos I’ve been posting, the TCU shifts much faster once tuned.   Increased shift pressures: as also seen in the videos, much firmer full throttle shifts.

      The fancy pants red shock tower brace is finally incoming from MX5 Mania, getting it shipped from 'Merica has been a long and problematic process, and GWR, the 'Merican supplier will not ship directly to consumers outside of the US, Mania basically had to order a heap of them, the colour choice was silver, or red, and we all know anything red adds 5 killerwasps of dynotorques..... Whilst it does fit over a 2.5, and I've seen a few photos and videos of it being installed and fitting, google also says it might get real close to the FAB9 intake front runner, people in the US says it does fit with the FAB9 intake, except for one person who said it slightly touched.......so there is that.....LOL..... As it seems that I am the first in AU to have this combination of parts there's no local knowledge about fitment, so I'm just a willing guinea pig in this endeavour, I'll cross my fingers and toes and hope for the best In other news, I ordered stuff from China  on the same day I ordered the 23° silicone bend from Victoria, the stuff from China arrived a day ago, the 23° silicone bend is still travelling around Australia thanks to Australia Post, and "may" be here next week

      Very good news...I contacted Racebox about it last night. My car is a 2016 so remains to be seen if it is compatible, requires a TCU swap, or is impossible.
