O2 Sensor Voltages Before And After Cat, what is the optimal difference in volts? Options

[slimV6]

Hi guys!

for all the thai experts out there doing mods on tritons or other MPI models. When removing the CATs from the exhaust system, how do you manage the output of the lambda / O2 sensors to ensure the MPI does not scream at you??

For some reasons it has become apparent that the cats on my v6 need to GO!!! but, how to manage the effect on the MPI? is there an optimal difference in the output of the upstream and downstream sensor outputs? If there is, what should it be?

I have read that some of these inputs to the MPI are manageable by potentiometer and or resistor addition. I would like to try the resistor option to 'fool' the system in the absence of the CAT.

Any suggestions from your knowledgeable minds??


thanks in advance!
