Good idea for a thread, see if you can capture an ultra-clear pic of the timing mark on the plug......
dont mean to be stupid but where is that?back of the strap i think?

that plug looks pretty good IMO
Not stupid at all..... This is what an information forum is all about.....
Basically the timing mark will show ON the plug if spark timing might be too aggressive or not aggressive enough. A good tuner can tell all sorts of info from just reading a plug. The pic below shows a discoloration of where the timing mark is. This can change from motor to motor, but in the interest of what you're trying to accomplish here, it'll be interesting to see what other people find. I have inside sources that say this huge #8 cylinder is NOT a tuning issue whatsoever.......
I cant see squat in your pictures, use the macro setting. Also, you really cant take a plug out of a car after normal street driving and take what you see as gospel. I've been talking to some good people about this ever since I pulled my #8 plug and tried to do what you are doing now.
You plug looks fine, BTW.

The best way is to start with fresh plugs so you can see how the plating on the ground strap erodes.
You can still kinda see some signs in your plugs, though. In my completely non-expert opinion, your AFR looks good judging by the color of the base ring, actually looks pretty rich. I think I can faintly make out the ground strap mark in your 3rd picture. They look like upsidedown U's from that angle. Looks a tad bit hot but nothing out of the ordinary from what I've seen. Compare it to the stock plug posted in the other thread and I think you will agree.

Sure you do. So let's hear it.
Best way to do a "plug run" is to do a high rev pull at normal engine operating temperature and then cut the engine off and come to a stop then pull out a plug.
From my experiences your plugs look good. If they are a tan brown that is where you need to be. If its white thats bad, also if it is dark mushy blackness. Reading plugs is not rocket science....

From what is pictured I agree. I would like to see further down into the porcelain area to see coloration.
