If you have an ebc fitted and dont switch it on doese that mean your car will run in safety mode all the time. Or do you have to just switch it on and leave it o the basic setting? Just wishing to know.

With mine it means that it runs at wastegate pressure, not safety mode, the mechanically defined pressure the turbos produce without any sort of influence. For me that is 5psi!

 

So yeah, turn it on set it up and leave it on at 12psi or something :)

How do you know its 5psi if your ebc is off with no power?

Umm.what about anyone else. I have a hks ebc .i put i structions in glove box but never treid to set it up. Didnt want to brake anything.i thought it just run like a norm car when off the more boost when power on and set up. U learn stuff everyday i guess.

My understanding is just that, the pressure isn't regulated by the ebc anymore so stock boost levels will be used, either 7 or 9psi with stock turbos, depending on your vac pipe setup.

Nice and useful if that's right if you have a hidden switch for it, call it valet mode :)

I have a HKS EVC 5 (V). It reset itself the other day and I had to set it up. I fumbled through the menus and managed to sort it out. I have a seperate boost gauge that read 5 psi. My EBC is in crackpot units, mms of Saki or Kilopascalles or something so it stays in the glove box.

Hmgs or what ever it is?

mmHg is american, millimetres of mercury, what a daft measurement based on some sort of vial of mercury benchmark. My boost controler is in Kpa, KiloPascalles which I think is metric, I work in Psi and Bar.

Yeah me too, the stock boost gauge is in that funny measurement as is my HKS boost gauge

Haha just realised the stock boost gauge I have is in Kg/cm2 I think so I have 3 boost readings that hopefully say the same thing in 3 languages :blink:

No I'm talking rubbish oil pressure is in Kg cm2. you're right stock gauge is mmHg

Im glad i aske now.does anyone know for sure. I did ask somone else and they said.depends on how its plumbed in what eles is left to work with whilst ebc is not on i think. I think im i to deep with this question.leave it to the experts me thinks

A turbo has 2 bits. The exhaust side that drives the other clean air pressure side. There is a small silicon hose/vac line/pressure line that goes from the clean air side back to the exhaust side. This silicone pressure line has whatever pressure your turbo makes inside it. This pressure goes into the wastgate actuator which is a sprung piston that when it gets the pressure moves a rod to the wastegate that stops the exhaust side generating any more pressure by venting exhaust gas round the turbine.

 

A manual boost controler or boost jet, changes the diameter of this line a bit and fudges the pressure it exerts on the actuator. An EBC nips and releases the line in the middle basically all the time to actively and intelligently fudge the pressure going to the wastegate.

Just read ypur thing about it being EVC not EBC. My understanding of this is that HKS simply call it that as there are valves in an EBC, not like engine intake and exhaust valves or VTC or any of that stuff. Just in the middle of that vac/boost line sits a black box full of circuits solenoids and valves.
