This method will only work if you have a progressive boost only system. But beware the afr will be different under different gears.

I'm leaning towards the AFR approach because it'l tell me if there's something wrong with the whole fuel system, not just the w/m system. But I might just try the flow switch approach. Thanks for the idea

I'm planning on using a Hobbs switch, 5v relay and use piggy for 2D afr/rpm signal - crude but should work at full boost
Other topic. Is the pump flow directly related to voltage? (ie. 8volts = 50% flow; 12volts = 100% flow) Or does the controller send pulses to control flow?
