Sorry, I didn't mean to sound critical. I was picturing you with a shocked expression and laughing at myself for thinking you needed to raise your hand. You'll be all over it next time and here's hoping you don't get too much practice!
I know you had good stuff in that motor , so I was trying to think past some of the obvious stuff and think about the ECU from a more general angle. The one I am designing is having some proto boards assembled about now, so I can't help but think about this a bit.
At one end of this, how would you know or would it be possible for the ECU to kill your engine that way? It looks like the little end broke in tension during an exhaust stroke? Is that it? Is that broken piston pin in the oil pan? Did the piston pin mark the top outside of the little end?
If the ECU should have saved data and it didn't, that's a real problem. This is an issue they had in the Toyota cases. No saved data didn't mean no problem. It meant the data saving code was mixed with the throttle code and guess why there was no data at the smoldering wreck?
Maybe the ECU didn't have code to save the data just because the motor stopped turning...
Anyway I'm sorry this all happened. Maybe I'm not the best for advice on the driving style vs. politeness. We didn't have point bys in my day. Students like me were well and truly scared crapless out on the track. You were taught to stay on the line and faster cars should be allowed to go around you. Passing in turns was discouraged though. Still if you think you can go faster be up close about it, no reason for the guy in front to have any doubt about it after a little while. It's just more practice for you, maybe someday you'll go wheel to wheel and going bumper to bumper is how to start.
I think your camera makes it looks like you have more space than you do though also.
