Perhaps a better overhaul would be one that replaces
the ecu and the AFM.   A guy bought some fuel
injectors from my vanagon stock for his Volvo.
Since everything is in the back, why not swap out the
entire setup but still using the temp 2 sensor, o2
sensor, fuel pump and fuel injectors?    gary

You could adapt a throttle position sensor to replace
the original
 wiper
rheostat, but I think the TPS is a mechanical device
too so you would
 be
going sideways.  A TPS would still be cheaper than a
AFM to replace.

If you don't want any mechanical wear you are left
with an optical or
magnetic sensor.
The problem is both of these devices are basically
high/low sensors and
don't offer a "range" of values as would be required
by the original
 AFM
device.

TM- you say you don't want to spend the time and
effort to convert to
Megasquirt, but by the time you re-invent the idle
stabilizer and
 airflow
meter you could already be running a modern, cost
effective, fully
 tunable
setup. *cough* MS...

Having said that, your efforts are appreciated and
make for good
 reading.
Keep bringing the ideas forward.
