hey i was doing research for installing a 96 LTI, OBDII using 4 o2 sensors into my 1962 Impala. i didin't want to run CATS on it, i found o2 sensor simulators. great, $85 i can get a pair from lmperformance, that wasnt good enough,

here's the schemadic for building your own o2 simulator.

i thought i'd share this in the LS1 since all of ya have after cat o2 sensors.
