1- The track will speed up the abuse of the road yes. In other words if engines are failing at 4k-20k miles when being tracked imagine whats in store for your DD at 50-100k miles, specially when having manufacturers denying there is a problem when there clearly is one. MX-5 is a road car and they hold up good at the track, a good friend of mine owns a race school and so far only one car has had an engine failure and it was covered since the car was stock. 2-He is entitled if there is a problem and the manufacturer is not willing to address it. So by not making a recall on shitty injector seals his engine failed, i dont care if it was at the track or in the street a bad call by the manufacturer caused this failure period. If toyota did not recall the unintended acceleration on some of their vehicles would you say its ok for a guy that died or got hurt at the track because his car did not stop when he needed it to not get any sort of compensation. Because even though the manufacturer denied a failure that they knew was going on he was tracking the car so it does not count. 3-There are problems on every car but at least they are solved. E46 m3's had a recall for earlier model rod bearing failures. I have a couple of buddies with E46 track cars that got it recalled and covered under BMW.

A quick heads up for everybody. This car has issues with detonation with the factory tune. I'm not talking about crappy Cali gas, but the ECU calibration guys at Subaru screwed up here.
This failed engine is a direct result of cascading failures due to a bad tune. Detonation is not normal and anyone who says so, ought to be doing something else for a living. Detonation over time will damage engine internals. This is a given. The first component to fail on this engine with the detonating tune is the nylon collar on the direct injector tip. When that insulator cracks and breaks off due to detonation, there is nothing left to protect the injector seal from combustion gasses and the seal fails as a result. Then, the failed seal leaks, causing more detonation and misfires until the engine throws in the towel (or a rod). This car detonates on the 2-3, 3-4, 4-5, 5-6 shifts when driving the car hard. By hard, I mean WOT and shifting with speed and authority. I have attached a log that shows detonation happening at exactly the shift points (you can see the engine speed rising to redline and the shifts). On the 2-3 and 3-4 shifts I logged, there was detonation resulting from too much timing advance which can also be seen in the log. Keep in mind that this is the factory tune and all I did was log what it does. I have also attached a view of the factory Transient Ignition Retard Table that shows that it is not pulling jack for timing in the high rpm range. It does pull timing at low rpm and low load, but keeps the timing too far advanced up top. This is due to the fact that the base timing map is advanced a lot in the low load range at high rpm (which the engine sees when you close the throttle for your shift). Apparently, there is a new flash from Toyota that fixes the tune...sadly, the tune is what ultimately caused the engine failures here people. Subaru needs to step up and fix their mistake. In closing, while not everyone drives their FRS/BRZ like a madman, driving this car hard will eventually kill the engine with the stock tune. Tracking the car only accelerates the inevitable death of the engine since you are shifting like this much more often. Last edited by Sithspawn; 06-03-2013 at 02:17 AM. Reason: edited for accuracy |

Depends on if your tuner has the updated flash. I don't think it has been released in the US yet but some tuners have it.

Not necessarily. If the tuner is not aware of the isse and doesn't correct it, then you would still have the stock Transient Ignition Retard Map and you'd still have detonation on shifts. Period. The ecutek or brzedit software doesn't fix the issue: the tuner must fix it.

I want to inspect my injectors. But I do have signs of damage. I am worried now that I have a ecutek flash toyota will blame that.

You can always flash back to stock when. Oh take your car to the dealer.

I got the inspiration to do a log specifically for this purpose as a result of this post here: http://www.ft86club.com/forums/showp...2&postcount=65
If anything, my log simply validates what Toyota already knows. |
