Performance tweak with STAR settings

Noticed under DRIVETRAIN / motor electronics / control unit adaptations / correction programming

There is a setting for fuel quality, anyone played around with this ? Maybe can take advantage of premium 99ron fuel ?

I have done many cars and recommend this. At the filling station fill-up with the highest octane available, and set the engine management to match.

I haven't seen a lot of discussion about it nor have any first hand experience with this, but Shardul seems to know some about it. Perhaps he can answer some questions for you?

here is a link to a post where he mentions it.

should be always set to self learning so engine protection purposes and also if you add race gas that has a octane content about 99ron them timing will be adjusted accordingly.

With the settings, I presume the 'base' setting is self learning ? Thanks
