Read my plugs
 
So I pulled my plugs out today just to take a look and the picture is what I found. The other bank is pretty similar. Procharger 6psi, Accel DFI, wideband, o2 13.1-13.4 cruise, 12-12.7 from 3200 to 6100. These are after a wot run and idling to the boat ramp, as far as last use, but are a season old all together. They look lean to me by the white porcelain, but not sure what to think about the straps. No soot in the transom, so I could probably go richer. Any thoughts?

Can’t be read after idling. For a good read put a new set in while you’re out. Do a WOT and basically get in neutral quickly and shut it down for a good read. Idling will throw the read off

AC - the pics are tiny, When you click on the they don't get larger,

That's weird with the pics. Here are the full size.
CI, I know the right way to do it. I just pulled the m to check and they looked unusual. I guess I would expect the porcelain to clean itself off that quick.

Why read the plugs if you have wideband?

You only get average with o2. Plug reading would be better if you have the rite stuff to examine them.

Timing, heat range of the plug and detonation is valuable to plug reading.

Bigger,but maybe photo wasn't taken close enough ?
Trying toread someone's plugs from a computer screen sucks anyway. LOL.

what heat range plugs you running. I don't think your going to read them with a picture unless you cut the shell off of them.

It's a NGK BKR7E, had 3924 come apart after 2 seasons. Had some deto in midrange and wasn't fuel control or timing related. Added fuel and pulled timing and didn't seem to do much. The next week boom. Not sure if the plug went or the deto pinched a ring, but top o piston came off. I jumped to a cooler plug last season, and may go cooler, doesn't seem like I'm having fouling issues with the 7, may go to 8.
