Check Engine Light without CAT

[Lextreme II]

Anyone have experience if your car have CEL with cats removed?

I haven't ventured down that road yet, but if a CEL was to be produced, do you think its possible to fool the ECU the same way the Subaru guys fool their ECU:

-Run a resistor in the ECU side of the o2 sensor plug, that makes the ECU think the voltage value is constantly correct.

john spina @ casper's electronics makes o2 sims for a variety of vehicles....

dunno how diff they coudl really be besides plugs
