How much does the waste gate open when it does? Half way, all the way?

The spring does not keep the valve from opening to it's max open position. The idea is to get your spring tension so that it helps keep the valve shut as boost is rising, but ultimately is overcome by the force of the actuator. Not exact, but think of the actuator as having a linear progression as it opens whereas the spring will change that line to a curve (like a skateboard quarter pipe). Make sense? Your logs are going to show you what's going on with the spring. You'll see improvements with spool as you increase tension, and eventually start to see hints of exceeding your target as the spring tension is too great and keeps the gate from fully opening.

Did you compare your spool (not just peak boost) with the gate wire shut compared to the gate in normal operation?

 

Not yet, I did datalog though. I'll have to take a look at it later. Although I havent figured out how so show boost in mega log viewer.

When in Megalogviewer look at the column on the left. These have things like CLT, TPS, RPM, etc. Left click directly on something you don't care about like CLT or one that's blank. A list will drop down of options for that line. Click on what stats you want to have shown. There's a lot there. This will revolutionize your view of MLV!

Jeez. The youth of today. Gotta do everything for em.

 

Um, I think not. And tell me what age you consider to be "youth".


I know about the different options but I donot see boost listed.

you have to turn boost on by going into optional fields and telling MLV what the typical ambient kPa is first....

 

MAP doesn't show?

Might be a dumb response since I'm just a user. I don't build the things. A little bit of knowledge can be a dangerous thing in my hands.

 

Im there, its asking me "Engine off MAP pressure in KPA" ?

Ambient value... here its around 98-100 kpa (confirmed this with scott earlier as I set it up on my work PC)

 

Mine says 64 KPA. I found this thread when I Googled ambient kpa and it should be right if I have a 2.5 bar map. Scott, is that what you gave me?
