can i use the lc1 to replace the signal from the stock 02 to the ecu or do i have to still run the stock one to ecu and use lc1 only as add on for tuning? and also when i first turn it on it says to calabrate it with the sensor in free air, does this mean i must have sensor not in the exhaust but just out sittin on the fender or somethin to do this or can i put it in the exhaust but jsut not have the car running?
