Here's my first set of OL Scaling changes:
This was done in 3rd gear WOT with WGDC=0. Frankly speaking, I was really doing things in the dark here. Luckily, nothing catastrophic happened.
I sent some of my logs to Rene and here's what he replied:

Ok, here's what I've realised. In some runs, my exhaust clamp for my wideband actually came loose. When this happens, my wideband was reading incorrectly or was logging the value of 20.33. This is bad and I should never have included them into my set of log data.
I'm more discerning now. Before I import the data into Airboy's spreadsheet, I filtered out any data that read 20.33 or 0 (or any data that gives extreme values as Rene mentioned above).
