Exhaust OCV?


DuCKy!

Recommended Posts

Hi all, so I've been having a rough idling issue ever since I've got the car.

Finally learnt about all the wonderful things you can monitor and log with a KKL cable and the BtSsm App.

 

I've had countless help from Andy_Mac, as well as the folks over at LegacyGT.com.

 

After logging a number of parameters, my LEFT VVT Exhaust seems to be very "lazy". Always taking its time to get up to the required angle, and taking its time to drop back down.

Whereas the RIGHT seems to be much more responsive to Load. We're talking up to 20 degree differences at times!

My LEFT & RIGHT VVT Intakes seems to be doing fine.

 

Check out a section of my log below:

Anyhow, I've been told that my OCV could be the culprit.

Now the folks over at LegacyGT do not get dual AVCS. Their 2.5L engine gets the AVCS on the intake only - so there's no DIY or any photos of where the Exhaust OCV is.

 

Anyone here have had experience in changing/accessing the exhaust ones before? Will also look at the Banjo Bolt filters.

Would rather get some knowledge before I start digging in my engine bay (I haven't even taken the engine covers off yet! :$)

 

Cheers

Nicholas

Champion.

 

Does this look like a dead OCV, therefore I should pre-purchase a new OCV first considering the effort to get to it?

Or just clean the filters in banjo bolts, take OCV out, clean with brakeleen or something and test it out again?

 

Also, since the Exhaust VVT Left is super lazy compared to the Right, I don't actually know how well the VVT Right is doing.

Should it be advancing up and down that much more than the Intake VVTs?

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
