If I may ask? Which spark plug do you install CHT probe on? I would like to know for both the six and four cylinders.
Thank you.
/4 the #3 cylinder runs the hottest.
/6 it doesn't matter as much, some say #1, some say #6....I used #1 just because it's the easiest to run to.
Edit: For the /6 the #1 cylinder is the easiest for me to get to as I'm twin plug and I have a lift. I have my sensor on the lower #1 plug hole.
On a standard 6 plug engine the 4/5/6 side may be easier to get to.
This is important because you must take care not to twist or cut wires on plug install. On my six I cut/notched the plug hole seal for the CHT sensor wires.
