Jeez thats Rad!!!!
I thought that this hybrid couldn't be done. Now I wish i'd hung onto my old CRX with its D15B and followed your lead. Any chance you will take it down the 1/4?...

Sorry to burst your bubble, but it does have an ECU. It is crude but uses that little black box for its MAP & IACV plus a bunch of other sh!t. Why else would it have an Exhaust Gas Oxygen sensor??
Your ECU is located under the passenger floor carpet, behind a metal plate.
Your Carbies run rich but the MAP sensor & Exhaust Gas Oxygen sensor use that little idle stepper motor mounted between the carbies to adjust air ratio.

personally i would love to have the knowhow on doing this sorta stuff... and im just wondering if any of the ppl complaining know how to do it? if u do, then fine, u might understand the difficulties, but if u dont then what's there to complain about? you'll never have to do it yourself so.........

anyway, good stuff bro, id still prefer efi but im jealous of your skills
