Not to bash the vendor, but it sounds a little flakey to reuse the airflow
meter with the door blocked open.  Maybe that's to preserve the "OE" look.
The air temp sensor is reused and they include a MAP sensor.  So this looks
like a speed density system.  Nothing wrong with that, though most modern
setups use a MAF.

And the idle control unit is eliminated?  What controls the air bypass?  Or
maybe the new system just bumps the timing to compensate.

For $1500 doesn't sound too bad if its plug-n-play.  New wiring is
definitely a plus as these vans get older.

OTOH you could build your own for quite a bit less, but of course with much
more time invested.

For some reason when they say it it sounds less exciting than when Jim was
discussing a similar possibility.
