did doug tune it?

 

My builder saw this post and his comment about the picture is detonation. He asked to see the tune file.

I will try and send him the tune file and also post it here.

Damage is already done. But I want to know the cause, not to blame anybody, but to avoid having it happen again.

I am just woundering if it is tune, why did it wait 6-months. I have stepped on it several times but not for long duration. The guy driving it was on a 100 mile trip on highway. I cannot tell how he was driving it.

 

A quick look at the plugs could of prevented this. Widebands are great, but plugs never lie.

 

Those plugs in the pics are pretty much ate up but look at the others. A sign of detonation is chipped/broken porcelin and brown speckles on the white porcelin.

Someone else driving it makes sense. It takes HORRIBLE detonation to do that to forged pistons. Someone with some sense about them would lift out of the throttle way before that happened. That took someone staying in it with all kinds of horrible noises and shaking happening. Sorry for your loss.

 

Definitely detonation- I have a boosted motor here that looks identical- #5 and #7 too- this one happened under full boost when the fuel pump went wonky and had a lapse in fuel pressure- for some reason on these injection rail setups, 5 and 7 lose fuel pressure faster than the others.

 

I would have to agree on detonation myself...I would be pissed that the driver didn't lift, there must have been signs of what was happening...

 

 

damn sorry to hear this bro, hope u get it figured out.. your truck is one of a kind

 

Same happened to me. #5 & #7 went under 180 shot of direct port nitrous and not enough fuel/too much timing for my poor stock motor on my C5.

 

I'm pretty sure that's #3 and #5, not 5 & 7........
