IAT log you don't want to see
 

what you see here is a nice cool charge temp, around 75 degrees, that rockets up to max temp.

that is what you see when a piston dissolves and a fireball backs up through the upper intercooler pipe and warms a sensor.


all the other logged items were hidden for clarity, except the falling rpms

Damn!

I didn't know that you logged your sessions.

I do when I can get away with it.
I have an entire log from Spokane over on the Innovate forum. If you have LW you can play with what you see. There is no "high drama" to my motor on that log.

wow, how'd that happen? I log all my sessions too. The data is priceless.

nothing like the real data is there?

Piston 1 went up in a cloud of smoke. The guys at English Racing are telling me it was too lean. No matter what, its all on me, my tune, my driving etc.
I mean the piston really disappeared, only thing on the end of the rod was the pin.

I had just gone from all h2o to 50/50 meth. Took out the hiflow cat and didn't reset the fuel. So I was getting up there.

But still... then entire piston... the plug should have been gone long before that.

nasty.

for interests sake what was the knocksum like?

Do you have the log file? Not at the innovate forum. Just curious, if the afr skyrocketed maybe the system failed to spray. Should be richer with methanol

^ Agreed. Moving from all h20 to 50/50 should have dropped the A/F ratio considerably.

aside from a hugh knock event about three laps earlier, which I think was false, there was a count of three showing at the end. The reason I think the early event was false, it happened once despite driving the same cycle over again(s) without a knock episode.


I was working the afr in the 12.5 zone. When I changed to a test pipe I never did another log.

Maybe there was a much higher event at the end that didn't get logged because it fell between calls?

C6, no the afr at the end was about 12.5, it had been leaner earlier. If I remember I'll post a snap shot of the last ten seconds or so tonight.

We need pics of the carnage!!!!

preignition will not show up on your knock monitoring.

Where do you stash the computer?

Bruce, if you can attach the log I am very interested in downloading and viewing it.

If you got more important things than digging through logs at the moment, I could definately understand with the motor torn up. But that log would be interesting.

Good luck with the new motor.
