When hooking up the LM-1 to monitor A/F ratios, can I use the bungs after my cats? I know the sniffer at the tuner just goes into the exhaust pipe and works fine getting the A/F ratio, but is this true for the LM-1? Sure would make my life easier if this will work! No new holes!!!!!
Thanks for the help.

I believe the cats will alter your readings so it's best to put the WB in ahead of them.

The cats will definitely alter the part throttle readings. The WOT readings will be slightly affected since the gases are travelling fast and the cats do not have time to catalyze. Best thing to do is to mount the WBO2 upsteam of the cats for accurate readings.
