[135i]

So I am about to go the drapstrip tonight in a feable attempt to diagnose a ton of weird codes I have been getting (vanos solenoid related I presume).

I am actually a complete novice when it comes to datalogging and would like to know what specific parameters is standard to log on my Accessport?

I want to log timing (timing or timing correction?), boost (absolute or just the boost..I want to see if I have a leak) and my Vanos system. My fuel pump would be good to check out too.

I know is the more parameters you log the less data/time you are able to log. Which ones should I select.

Thanks for the help!
