I have installed VAFC2 and tuned with some other modifications as well~

I have previously tuned my VAFC2 with Shell 100 Octane, than I put BP and Mobil fuels into my car and got these figures~

I got these Air Fuel Correction (A/F-C) figures off my Blitz R-VIT type 2:

1. Optimax Extreme (100 Octane from Shell)
The air fuel correction goes from around -3% and up to +43% peak

2. BP Ultimate
Around -7% to +23%

3. Mobil 8000
Around -15% to +13%

*these figures are collected under the same mods and VAFC2 settings

By looking at the figures, someone must be able to interpret the difference between the fuels~ I am interested in that as well~
so can someone explain~?

Also I want to know which one would be the best for my car to use with my VAFC2 settings or it doesn't matter?? (i am more concerned about engine protection/damage :p)

to Admins: if someone posted similar posts or i am posting in the wrong place, sorry~ ^^
