So when I bought the MaxxEcu almost a year ago now I also went ahead and bought two Type-K temperature sensors to be fitted underneath the spark plugs. I figured I wouldnt need them for the first iteration of the engine but now I’ve changed my mind and this past weekend I set to taking the engine tins off with the engine still in the car.
The sensor ring fits underneath the sparkplugs on the #2 and #3 cylinders but for the cable to fit into the sparkplug recess I need to notch the head a little bit at 12 o clock above the spark plug. I sacrified a sparkplug to make a low height plug for the sparkplug hole while grinding the notch with my old Dremel tool.
Looks like the cable will fit now.
All done, time to refit the engine tins which was a minor PITA.
