I am sure it ran great, till #3 gave out.
I wonder if the knock sensor picked that up.
Usually #1 will go first most the time. I see that #1 already has a chipped piston too. But I have seen my fair share of #3's put windows in the sides of blocks. Best one was when it went, and took out the pan and the starter when that rod was thrown.
I would say your used block, and a few parts are still of value...to me.

All tunes should be done for the exact engine its connected to. Off the shelf tunes are great for mildly modified cars. ZZP, and Intense PCMs...uh...no. I would stick with a DHP, and I have heard good things about overkills PCMs.
Sucks man. I would order another engine from ED, and swap your parts on over to the new engine, and tune and drive till the next one goes. Hopefully not for some time.
