ECU Logic for HX Civic?

also this will depend if you have a VX or HX. The HX searches for the "edge" via the knock sensor not the O2 reading.

rkcarguy, can you tell us more about the HX ECU's logic??
Anybody else have some background on this?

I've been using my ScanGauge displays, grill blocks and warm air intake to keep my '97 HX in lean burn as much as possible. HOWEVER I have to work mostly on assumptions and hunches as I don't know the ECU's logic.

So far I've been able to do better with a thorough grill block on the cat side of the grill. However it still goes out of LB for reasons I can't fathom.
