1. You wnat to add the H2O as close to the intake valve as possible (thus
avoiding puddles, etc.)

2. If you are using compressed air to to the atomizing (of the fuel AND/OR
the H2O, shhhh again), it's almost trivially easy to know how MUCH of it
you are using. A correction in the ecu is therefore not difficult.

3. Wasn't planning to use MAF.
