Dont know what you have going on there… I welded the bung on to the side of the pipe a few inches away from the stock WB O2. Even calibraited it in the pipe, your suposed to do it in fresh air hit the button and then stick it in the pipe and complete the process. Even with me not reading the directions its dead nuts on with the same readings as my stock WB O2.
I even pulled the battery for 2 months on the car and fired it back up, didnt even calibrate it again, and once it warmed up it was again right on with the stock WB O2, i assume the controller has a watch battery backup or something.[/QUOTE]
My Corvette makes an LC1 come up with an overheat message (sensor about a foot from the turbo), where as the FJO works fine.
