Dumb Question: How do you delete the rear 02's using LS1Edit?
 

Which area of the program do I use? Is it the "Hardware Diagnostics?"

Any help would be appreciated.

FYI,
you are not deleting or turning off the O2s,
you can only turn off any DTC errors they can trip on via as you metioned the diag section so that the PCM does not trip SES light or store the DTC code

Hardware diagnostics. Find the code you want turned off and set it to 'Type=X'. Like Team ZR-1 said, you are not turning the O2's off but just telling it not to display the code.

Thanks!

I'll give it a try tonight.

P0137, P0138, P0140, P0157,P0158, P0160 are the most common ones to go off. might as well turn all those off while your in there.

Thank you Nick--I couldn't figure it out either.
