Hi,

I have been out this weekend and been testing VR6 3.2T BUB project.  Car now feels over all OK.
But there is one thing that i need some diagnostic help with that I am not sure where to start and what to log. Problem occurs when im between 1200Rpm and 2000rpm. The engine suddenly hesitates in a very short "dipp" almost as if it wants to corrects it self but then it allows it self to rev up after that dip.
(The engine wants to do more than the computer it feels)

I have some theories:

1. It my VVT that kicks in and due to the advance of the intake cam (30 degree in logs) it blows boost (very little boost at this time) right through the head creating a wierd MAF/Load value.. (Kinda thing)

2. Its my KFMIRL/KFMIOP that incorrect and need to be tuneed better.. I have only Touched KFMIRL and increased the last columns.

3. Something has to do with the variable intake runners (kinda thing?) It switches over from something.

4. KFWDKMSN Has something to do with this sudden dipp in power..

What can i Log to determine the issue?

Thanks DD, will do some testing and loging tonight and se some results..... my car is still on the lift and need som welding

100% in that map is = Disable right?
