o2 sensor location / position

Have a question on position of the O2 sensor.

It says to mount it on drivers side.

As my swap is super tight on that side what would happen if it's put on the passenger side?

Just throwing this out there as I don't want to break something.

 

Thanks

As the ECM will adjust both banks equally when using only one o2 sensor, I can't see it making any difference. Call Fitech to confirm.

However, the system will adjust banks sides separately if you have two o2 sensors, which the LS system will easily read. This results in the system better tuning itself. The GM LS system is designed to work with two o2 sensors adjusting both banks.

Thanks..

I will give them a shout..

From what I remember in the instructions they wanted to be in the #1 cylinder side, which in a Ford is the passenger side. You Chevy guys are stuck with the driver's side. The idea may be that all is based on the #1 cylinder, but I can't see how will it make much of a difference.
