Also I have a comment about you aiming for green LEDs. I seem to be getting more power with 1st and maybe even 2nd yellow lit up. I have jetted for green at cruising speeds, for economy and smoothness, and to get top end 1-2 yellows.
I think that that particular location would make little difference in the EGT
But I am also a fan of wide bands over the (from my understanding) lean/stoic indications you get from narrow band sensors.

Is that sensor heated?

I have an LM1 I want to use to tune my 640. I either need to weld on a bung or try an exhaust adapter. Id be interested in others opinions on the sensor position.

BTW: Nice work guys

I pray that you dont look at me
I pray I dont look back...
