Question CA vx with 5 wire o2 sensor?

Was reading this thread:
about a 94 CA vx with 5 wire o2 sensor and a CA ecu. Is this possible?
I thought you needed the fed ecu to make it work. The reason I'm asking is that I have a CA 94 with a 5 wire sensor. Discovered it after purchasing a 4 wire sensor and attempting to install it. I checked the emmission sticker and it's definitely California.

Is mkiVX still on the board? If so, did you do a conversion?

Anyone else have a guess?

"1994 civic vx all stock ready for high mpg!


Ok gassavers

i have one of my vxs for sale
it has high miles but its been well taken care of. 270,000 miles
this is the dream vx with the 5 wire federal o2 sensor in great shape
I will try to describe this car as much as i can for the gas misers here on the forums.

#1 wide band 5 wire o2 sensor
#2 all stock absolutely no mods done to the car
transmission is PERFECT also the clutch is new
has a California p07 instaled great for all of you cali guys for the smog and
i also will include a plug and and play p07 A00 federal lea burn ecu
WHAT ELSE COULD YOU ASK FOR. i got this car on a trade for some work and i wanted it for my wife she opted to go with the 99 4 door ex getting 30mpg
what can i do.
now the last owner owned it since 35,000 miles and i promise this thing runs like a champ. has factory air conditioning"

Yes, some of the CA ECU's came with wideband O2's, but nevertheless, the CA ECU isn't as aggressive with lean burn as the federal ECU's are. California at the time was the only state with the stricter drive cycle emissions requirements.
