I just installed an A/F sensor from Aeroforce. It works good. I just want to make sure I have calibrated correctly. The directions are a bit strange in my opinion.

They say that the car has to be cold at least one hour after running the engine.
Do you calibrate it with the engine running or off?

Further, I can data log at the aeroforce gauge. Can I datalog on my SCT and how do I connect the instrument to it?

Thanks!
