#1 Rear Still Hot

OK, I was hoping you had the same old probes in the same locations on the new engines as in the old engines. If that were the case, I thought a likely probe issue but that would appear not the case based on your probe swapping attempts.

I agree it is probably unlikely your new GAMI injector has an issue but it would still be worth verifying. It's not impossible.

I'm guessing you have a relationship with Savvy Maintenance and Mike Busch.?.?

What do they say about that cylinder temp and what to attempt to do to solve the problem?

A picture of all of the baffling around the engine would certainly be helpful.

I have a few but they are not great. Will take all the cowl covers off and do full pics soon.

It is quite helpful to have a bright drop light in the lower plenum area and look for light leaks around the baffling and all of the poorly sealed areas around the motor. Look closely to the area across the top cowling where it is scalloped. I'm going to devise a fix for that. I'll send pics when I do.

Also need to check the continuity of the wire from the rear probe to the panel. It's entirely possible it's chafing the way that cyl temp jumps around.

Also should put the factory cht probe on the #1 cyl to confirm temps.
