If you haven't do so already, you should compare
your design to the EFI332 one at

A few more quick thoughts. GENE already pointed out that for a 4cycle
engine you're talking about half of 85%. Also, I think most
OEM port injectors have a higher resistance (15+ ohms?).
This makes your power consumption figures look **much** better.
Also, mounting your module in the car interior as most OEMs
do helps your underhood heat problem.

When's the prototype scheduled?   :)
