    i swapped a ls into my 91 crx si. i used the stock ecu. but schould i get the 91 teg ecu? how much power am i losing? also when driveing for a while the cel comes on and says the o2 sensor is bad then i shut the car off for a second and the light goes off and car runs fine after.

    either chip your stock ECU or use the teg ECU. nothing else to be said.

    the fuel maps are all wrong.
    get the teg ecu.

    it may solve your o2 problem as well- due to it giving it the wrong fuel and making it run improperly
