eCtune

Just did a little tuning and pulled this plug right after a pull, cutting the engine almost immediately. Is the greenish colored mark the color change I am looking for with timing? (This picture was taken after I drove home, the color was much more defined at the time)

That plug looks very good.. Reading the strap(around the 90 degree bend) your timing seems spot on.. and from what i can see, hardly any detenation.. looks good.
