I've installed a high-flow cat converter on my '99 Integra and after installing a O2 simulator to take care of the check-engine light on my dash, i keep getting a high-volts error code (O2 Sensor High-Volts - bank 1 sensor 2).

i tried all kinds of things with this O2 simulator - adjusting the High Volts, the Low Volts and the Frequency of the signal.

Does anyone know how to get rid of that "check engine light" once a high-flow is installed on an Integra?

any details on previous experiences would be helpful.

thanks much!
