The new engine has dual plugs per cylinder (it took me over three hours to change the plugs...) They have one COP driving two plugs each, like a wasted spark idea. The signal goes to the c...

Tuners: There is a way we all can get around "sluggish probes" and predict what the instantaneous actual EGT is (or CHT or CLN etc.) The method is used on dynos but is a very simple formula if you're willing to do a little testing up front. For every brand of sensor and for each setup (1&q...
