Interesting read for those on here that are real tech heads about engine mechanics.

Couple important notes on this setup:
- Direct injection can, over time, suffer from carbon buildup due to the absence of cleaning agents on the exhaust side of the intake valve. You'll notice the injector spays fuel on one side of the intake valves only; so traditional fuel cleaners do little to remedy this issue. Modern DI motors have changed their configuration to minimize this issue. But it may still be a problem on high mileage motors. Use good quality oil (for blowby) and fuel high in detergent.
- Turbo motors benefit greatly from PCV catch cans. In short, blowby from the PCV system sends oil mist and gasoline fumes through the intake manifold, which accelerates buildup on the intake valves. A catch can collects this blowby to help limit buildup on the intake valves, 02 sensors, and cats.

I'm glad my FRS and the Civic will be able to use the same motor oil (0w20). I wonder how using higher octane gas would help. Obviously the combustion would and should be little different. I'm guessing tuning would have to be involved?

It wouldn't. The ecu would compensate for the higher octane automatically. The only "benefit" is higher detergent concentration.

In the future, however, high output tunes that advance timing could require higher octane or even E85.

How do I tell which fuel is high in detergent? They just label the options as clean on different levels. Is it a special additive?

Usually the higher the octane the higher the detergent level (hence why high output turbos require premium fuel as well as the fact it combusts more easily)

I do hope it wouldn't need a tune to take advantage of the higher octane. I do have a few plans to gain little power here and there. I hope there will be an OFT (Open Flash Tablet) for this car that will be plug and play on downloadable tunes.

Hondata will be on it forsure... I bet a slight rejig of the AFM will net you a couple ponies, or at least the feeling of a couple more. From what I understand most modern cars come from the factory so lean that there are gains to be made from slightly richening the AFM...

Even if it's not entirely similar, they should at least have a framework to work off of that helps to work on the ECU, has to have some level of similarities.

Don't bet on it! I couldn't get Hondata to do work on the 1.5 L15B N/A.

As a matter of fact, if this ECU is anything similar to the 1.5ltr L15B ECU in the Honda Fit, Ktuner has already got a start on it.
I don't know if they've had a start yet, but I emailed them earlier and they said yes they have plans to support the new platform, but didn't respond with an availability date...(yet)
