Appreciate some input on spark plug reading

What's the 5 gas telling you the gas balance is and what's the calculated AFR?
What's the arc duration time and how smooth is it?
What are you using to log the data from the pull?

Don’t have a 5 gas. Looked into it. It’s a fools errand unless you think you need to save the world.

I haven’t hooked up the scope to it yet. Probably won’t. It’s a 630ish hp engine. A decent Chrysler ignition would fire it.

I use Performance Trends to run the dyno.

Let me see if I follow your logic here…

You think the area around the plug is lean. So lean it won’t color the plug. But…taking fuel away from it is still gaining power.

If it was that lean at the plug and I made it leaner no ignition would fire the plug that lean.

And yet it picks up power as I go leaner. And it’s still rich.

Again, you are wrong. Someday you should look back on this and understand what a perfect dumb *** you are.

I’m on the phone with the best people in the country and they agree with me. And yet and still you continue to argue with no basis for it.
