Tom,

Try switching the EGT probe from #3 to another cylinder.

Subject: [LML] Fine Tuning EGT's

I have been chasing a problem with my EGT's and have hit a wall. My #3 EGT is about 80 degrees above the rest of the cylinders. It also has the highest CHT, but only by 10 degrees over #4. Yet #4 has one of the coolest EGT's... #2 is the first to peak while leaning.

So how many gallons did Jimmy have left in his bucket after Jane.... Just kidding. Sounded like a math quiz.

A better way to explain it, see graph below.

I have done everything I know to do and can't seem to figure it out. I have switched injectors from #4 and #3 thinking the injector may have been the problem. Didn't seem to change anything. I have done my best to check for a leak in the intake system. Couldn't find anything.

Attached is the data that goes with the graph.
It is a Superior XP-400SRE prototype so I don't exactly have anything to base my data on.

Anybody have any ideas?
