I think you are misunderstanding my response - I am suggesting that using the vacuum as an indicator to fool the MAF with a diode might also be accomplished purely with electrical modifications. Instead of the path 'electrical signal to EGR transducer to AirTrol vacuum sensor to diode inline with MAF', just do 'electrical signal to diode inline with MAF'.

I think I'll perform some experiments with the signals to the EGR transducer to see how the signal behaves. Once I get that info I should have enough information to draw up a circuit that should provide the same behavior on the MAF as your vacuum sensing setup. Customizing the K40 with an EGR on/off switch would be sweet.
