Just to get this out of the way, but you do have a Boost-Cut-Controller installed right?Luke (or anyone else) if you can help me out with some questions/problems i'm having with the EVC-S, it would awesome.
My car is set with BPU as well and i just installed the EVC-S . After fiddling with it, reading the instructions, and reading this entire thread i have came to a bump on the road and alittle confused.
It looks like the off set value is primarily used to set the desired boost (while using overboost to tweek). The confusing part is the Off Set value is in percentage, so what is it percentage of?
Looks like i am not able to boost higher than 13.9-14psi any way i change the settings. First i kept the Overboost at 3.0 and kept raising the Off Set until i got to 14psi (Off set was 70%). Since i wanted to get to 15psi i raised the Off set to 80% then even 90% but still couldnt get it any higher.
I started to raise the overboost but still got nothing more than 14psi (I set the Warning to 18psi just in case). Even bringing the offset to 70% and Overboost to 16psi, still kept getting the same result.
So anyone have any ideas what i'm doing wrong? My main head scratcher is what is the Off Set precentage of?
Man i had the EVC-5 and EVC-EZ for my past cars and this is the first boost controller i couldnt just SET the boost to a designated psi.
This is hooked up correct.Luke,
I went and put all the vacuum lines back to stock configuration and set the boost controller up like a poppet type wastegate. I took the vacuum source I've been using for my boost gauge (same source recommended on MKIV.com for their boost gauge install) and plugged that vacuum source into the NC port. I then hooked the unused line going to my boost gauge to the COM port. This is correct right?
At say 50% offset should I see 5 psi no matter what overboost setting I have?
I would think that a OFFSET of 50% (example) would open the solenoid 50% of the way regardless if the boostsensor is hooked up. You'd think that would just be mechanics working there.Luke,
Also, is the boost sensor just there to convert your source boost pressure into the digital output on the controller. Wasn't sure if this pressure was used as a reference of some sort for the actual solenoid. Since I have the boost sensor hooked into the same line as my boost gauge the digital output on the EVC-S always reads 0 psi too while testing like a poppet valve. Thanks for the help so far.
One more thing yes;Do you know of anything I can do to trouble shoot this thing further?
I cannot say, i'm just working off of my own experience / gathered knowledge.If I were to tap into the wires going to the solenoid would setting different offset on the controller yield a different voltage on a multimeter? Say 0% offset would equal 0 volts and 100% offset would equal 12v? Or does the voltage start at 0v and gradually raises the voltage as boost increases? Not sure if you would even know that information, but I'm trying to get a better idea of how the solenoid actually operates.
Should I be using a different boost sensor source other than the same source as my boost gauge? The set up I've been running has the boost sensor T'd off my boost gauge line.
