I've been following this sub forum for a while now (and props to Steve99 for his contributions for Aussies and his bit on knock correction for Aus fuels despite me having no idea what he's on about).

I'm still on the fence on getting the OFT due to the below though and I was wondering if you guys could help out.

1) scepticism on actual improvement over stock (with the updated ECU factory firmware, most DI and RPM idle issues are resolved) and the placebo effect of people feeling a difference of 10 whp. Other responses of "revving smoother" and "feeling better" also trip alarm bells.

2) unsure about long term ramifications to engine from the tune with our Aus fuel even on 98 Octane. Would I need to go with the 91 tune or the 93? It seems that RON 98 = AKI 93 but other alternative calculations peg our RON 98 at around AKI 91-92. And if I use the 2.01 OFT 93 tunes will I need to do further correction for our Aus fuel to prevent knock.

3) have no idea on how to read data logs or what I'm looking at. I might as well be reading a menu in hieroglyphics. Hence I don't like to purchase things or mod the car in a way I don't understand.

Also if I don't want flat foot shifting or launch control (unnecessary with a car of 200bhp), are these loaded automatically or can they be dialled out with the included bundled OFT manager software?

Thanks again.
