Just a thought about that -- does it seem reasonable that something
like an Arduino board could supply the necessary to drive and read
the MAF and intake air temp, then convert that to a T-I and AFM
output for the ECU?  It would have to supply rate-of-change
compensation since the mechanical inertia of the vane provides a rich
mixture on sudden throttle opening.

The MAF that I once knew a tiny bit about kept the filament at a
constant temperature.  It read voltage across the filament to
determine the temp, and the output was the amount of current
necessary to sustain that temp.  All the smarts were in the ECU, I believe.

Yrs,
