DI is a new realm for "engine builders" and all of us. I guess we shouldn't be surprised that Subaru has dropped the FA20 in favor of their own FA20DIT before the FA20 even finished its freshman year. Turbos really help DI engines meet that compromise of tuning for power, emissions, and reliability.
Hopefully with the help of the internet we will get resolution from Toyota. With CSGmike's story of two engines both failing for the same problem and subsequent warranty denial there are a lot of others out there with this issue but they can't be vocal for the fear of warranty denial, that's why this forum has been fairly silent about the issue.
Until then I am parked and man it sucks to drive my Yaris after driving the wonderful FR-S for almost a year  Without a doubt the FR-S is a $10k better car than an econobox, as long as Toyota nails reliability on the engine this car will be a huge success. |
Couple things, I did see the article about the turbo, but then also read that it wasn't for our cars. While I will admit that I know very little about turbo setups, I do, however know my fair share about supercharging setups. The simple solution to a turbo/oil cooler can be found in the tune. Some of the hard core trackers had an oil cooler for their cars, but most just fixed their heat issues in the tune. I had two tunes on my cobra. One for the street (basically a safe tune, but did have the potential to get hot), and an open track tune (less timing more fuel). While putting down less power, the car could take a beating, and run throughout the entire session without going into limp mode. There is no reason why a similar tune can't fix the detonation AND heat issues on the car. The trade off will be less power...which this engine really can't afford. Obviously just adjusting the tune at that point will have a smaller effect on the car (fuel at tip in), so I don't see that as being a bad option for a "fix." Being that my car is under warranty, I'm waiting on Toyota to actually do that fix without having to go to a third party tune.
As far as you not driving your car, you're crazy!
I don't know how you can stay away from her! I get up every morning and figure out somewhere for me to go so I can drive her around. Daily driving the car doesn't seem to creat these issues, so I'm not overy concerned. I have 60k miles before I have to come up with my own solution. Until then, if a DI fails, I have a second car (Toyota also provides one), and I won't have to pay a penny to have it fixed. Win win!
The DI scare of 2013 is no reason not to enjoy your car and rack up mileage. :happy0180:

I know you won't respond to me, but the good news is that as far as I'm aware, no one has had issues with the DI system on these cars because of autox, which is AWESOME. Because there is only one shift in the beginning, the lean condition never arises. Furthermore, because the races are so short, there really isn't a need for an oil cooler. Obviously, if you plan to OT the car, it's a different story (longer sessions, more heat, higher RPM's, more shifting), but there should be no negative failure from the DI system from autox.
