Bobby,
thanks for the info on wide band O2
Yes, address 43 dropped out to zero

Ed,
I'll try running with out the hushpower.  It's easy to do. Still sort of quiet.  About the same sound as an unmuffed O- 540.

That's a good idea on the B side.  Is it possible to reset B back to the default?  I assume that you switch to B and just reset to default.  Or de you have to default A and then copy to B?.  Can anyone confirm how the controller works with this?

I have a similar system for my fuel pumps and lines now, but with out the boost pump.  Many vapor lock problems and fuel pressure fluxuations, but cooling air,( 1" duct) shielding, insulation and firesleeve slowly solved it.

Thanks guys,
Don
