Honda's DPFI uses two injectors that operate completely independently from each other. With the MPGuino connected to only one of the injectors, you will not be monitoring all the fuel used by the engine. I don't know how useful the data from the MPGuino is in this situation, which has kept me from getting one.

With a quick web search, it appears you're spot on.
"This Dual Point engine came in two horse-power configurations, with the base four-speed hatchback getting less punch than the five-speed and A/T models."

What you're saying probably explains why SOME of the MPGuino readings are NOT showing up. Bummer.
I'll letcha know, if I find a solution, so you can get a MPGuino, too.
Thanks, Gas Fumes!
