I am going to take a stab at balancing the throttles tomorrow.. Anyone do this before? I am going into it completely blind, so any advice would be appreciated. This is for a '00 885i.
I have a set of mercury sticks, and a friend to laugh at me while I work, so I should have all the tools I need.
Where did you sample the vacuum? I was going to remove the vacuum lines between each body and use that as the sample point (it looks like there is a vacuum line off of each body that goes over to the airbox). Is this just a vacuum system, or is this the idle bypass air? It looks like the throttles are fully closed at idle, so I was a little concerned about using these points..
I was only going to sample the pressure at idle and around 3k.. Does this sound right?
What is acceptable variance? I was thinking +/- 5% of indicated vacuum.
Thanks!!
