Where to put wideband bung? I am a bit confused atm. I just bought an lc-1 wideband. Where should I put the bung? My exhaust setup is lts, ory, catback. Should i just not even bother welding it on and go with an sd tune & replace one of the stock o2 sensors?
I may go with an sd tune since I will have access to hptuners and will be able to adjust stuff.

I've also wondered about this. I know most tuners assume both banks to be equal in comparison but I don't believe that to be 100% true all of the time. I've wondered if the wideband should be place just aft of the merge in the y-pipe in order to monitor both banks. However, I don't know if there is enough thermal energy left in the exhaust to get a proper reading from the wideband even though most widebands can be tailpipe mounted.

[QUOTE=2002_Z28_Six_SpeedThe best way I have gathered so far is to put the WB in the stock position and sim for NB while feeding the output to your computer. I hope that the WB can pull double duty without changing the reading from the analog out too much.[/QUOTE]
What all do I have to do in order to do this for hptuners? Do i have to wire the wideband up to the stock computer as well as the lc-1 harness? Or can i do it some other way?

Placing it that far back will make the reading slightly off though. Probably do-able.
Monitoring both banks doesn't make sense to me though. You can't tune for both banks in the computer so why do it unless you think you have a serious problem AKA NOT TUNING.

Verdad Gallardo The fuel trims are adjusted from the pre-cat o2 sensor voltage, and it's the fuel trimming where you can see the small discrepancy between banks. The chemical reaction in cat's can skew the AFR if the wideband is located downstream, but I seem to recall it's only a couple percent.
