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.
Yep, there are several OCC's available for the Fiesta ST. It would be a worthwhile investment to put one in any DI engine, especially one that's boosted.
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?
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.
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)
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.
