Hi All,
Please have a look at my engine data from my test flight today and would appreciate thoughts on why the CHT's are high.

I finally got into the air today doing a test flight with my Instructor after the new GDU460 install. I am not sure if this would have adjusted the timing of my pMag or LSE Plasma 3, but my CHT's are quite high across the board and one peaking extremely high. We did a few circuits to see if the temps would cool down with the mixture rich, throttle pulled back, and airspeed. They did a little but still too high.
I pulled the cowl afterward and did notice CHT probe for Cyl 1 wasn't installed as deep as the other probes. I fixed it but am unsure why that would result in a higher temp.
Baffles haven't changed and prior to this it was high 360-390 but rarely over 400 for more than a few seconds.
Previous to the install my oil temps did run high, my oil cooler is at the front and not what I'd consider being the ideal placement but my oil temps on today's flight didn't really alarm us.
I'm not sure if timing could do this (preignition?), or what else the culprit could be. Again, thoughts would be appreciated.
thanks!
