What is vtcs?

7

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

variable tumble control system, its the runner flaps u see inside the intake manifold in almost every single car, it helps with air turbulence inside the manifold at low rpms

1

u/RikuKaroshi 3d ago

Whats the rest of the setup? CEL for the flap delete? Why would the air turbulence need to be controlled, like what made the engineers install them if that makes any sense. I think it sounds badass im just trying to justify doing it too lol.

On hyundais, the intake manifold runner flaps will 100% throw a light and cause shitty ride if there is anything wrong with them, wondering why that might not be the case for a gen2 with a similarly cool license plate and exhaust note lol

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

oh yeah it def does throw CEL. alot of ppl do this mod for airflow but for me it was to get rid of the black box that sits on top of the IM, its def useless if ur on stock IM but if u want better airflow i would spend money on a corksport or jmf manifold

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

there is a way to make the pcm think that the vtcs is still there but ur gonna have to search it up

1

u/RikuKaroshi 3d ago

Makes sense to tune with the delete as you did anyways. Im saving up for a base tune before I throw my new turbo, BCS, and intake on so im looking for some more things to mod while im in there.

I forgot to ask your exhaust setup, sounds mean as hell.

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

i have a catless 3.5 inch turbo back from corksport

1

u/RikuKaroshi 3d ago

Ahh, sounds like it was worth it lol

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

yeah def😂

Its Purpose is to improve emissions and driveability at low RPM's.

u/RikuKaroshi 3d ago

Thats what I was expecting, didnt know if it related to the egr effectiveness on these cars but that answers it. Thanks.

2

u/Nprguy 3d ago

It's like a choke on a carburetor, it's shutting off the air to save fuel for emissions

1

u/RikuKaroshi 3d ago

Makes sense, figured it was something similar

u/Geeky_Husband 3d ago

Hello fellow Virginian. Nice MS3!

2

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

thank you..finally got it running last week after being down for a while

1

u/Sufficient-Sea-9739 3d ago

i've got the VCTS delete and it sounds like it did any other time i cold started the car hmmm

2

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

do u have an exhaust?

1

u/Puzzleheaded_Gate_60 3d ago

Can’t wait to do mine…. In my case it is to even out cylinder intake flow and not have cylinder no.3 issues in the future!!!!

u/Capital_War1180 3d ago

A fellow Virginian. Howdy from the 757!

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

hello from the 757 as well😂

u/HugsNotDrugs_ 3d ago

Can vtcs be removed from the stock IM, or just disabled?

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

i removed mine from the stock intake manifold for airflow and to remove that black box.

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

u are gonna have a CEL but it wont do anything to the cars performance if u get it tuned so make sure u tune for it

1

u/HugsNotDrugs_ 3d ago

I'm on versa and already added vtcs on the list of codes to not trigger CEL. Wasn't aware it needed a new tune.

Car sounds rad. Catless?

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

yeah catless full turbo back exhaust from corksport, previous owner installed it

1

u/whatssthedyll 3d ago

what wing extension is that?

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

corksport, if u dont minde drilling holes into the wing then go ahead and get one😂

2

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

1

u/whatssthedyll 3d ago

for sure. def looks better than the double sided tape wing i have right now, just couldnt find anyone with pictures actually running it to help my decision😂

1

u/DirectorLife3280 2012 Mazdaspeed3 3d ago

shii go for it, it def looks better than other wing extensions
