I think I have a new hero. Klaus, you are the man.
The hobbs swith I have connected closes at 3 psig rising in the intake manifold and grounds the O2 sensor, making it go rich. Based on your explanation that does make it go very rich under boost EXCEPT at full throttle, obviously there are better ways to do it and the LM-1 is going to get me there. Basically the only time I hit boost is under full throttle, so the hobbs switch is useless.
While I am well schooled in the mechanical field, my skills in electronics are limited but I am learning with the help of folks like you.
thanks again.
