     I've downloaded a monitor program advertized to run on any Palm 
device with serial I/O, and it runs
on my Palm 105, which I'm willing to dedicate to the task since it 
currently has no other duties. It does
indeed have, on screen 2, a readout of air flow which can be 
displayed in grams per second or pounds
(mass) per minute. It also has displays for fuel mix adjustments, 
RPM, and a host of other stuff. This
should serve my purpose.

     Now, to get the hardware that will enable said Palm 105 to talk 
to the OBD port...

     I'm wondering, maybe it would be feasible to borrow your 
equipment, plug that in, and connect a
VOM to the MAF sensor wires to hand-record for a graph of output 
voltage versus air mass flow? Just
what *is* the output of this sensor?
