Default The tuning chapter...

Figured I would just go ahead and move the latest work done on my car into a separate thread, since most of it has to do with tuning lately. I may go back and fill in stuff that was done earlier so I have a record of what I have fiddled with in case I need to refer back to it.

Anyway, the latest, first....

Did another data logging run yesterday. I've noticed that the short term fuel trims were fluctuating quite a bit, so I wanted to disable closed loop mode to see what was going on.



Car ran really well in open loop, but seems to be running a bit rich in most areas of the VE map. I disabled the fuel modifiers last night and will do another run today or tomorrow to see if that helps lean it up a bit before modifying the VE (volumetric efficiency - B0101) table.
