Is it advisable to apply anti seize to the threads on the sensor before installing it into the bung? Or would that interfere with its performance?
Thank you for your question. That is perfectly fine to do.

I am using an aftermarket EMS and want to use the 6178 to read the AFR. I need a voltage to O2 calibration table for gasoline with a SOT of 14.7 (factory default) so that I can calibrate the gauge to the EMS.
Thank you for your question. Please call our tech line at 866-248-6356.

I have an Autometer 6178 I believe this is the correct O2 sensor. Can you verify that?

Can this be used as the replacement O2 sensor for a FAST EFI 1.0? The specs on the FAST sensor are "LSU4 Wideband, 5-Wire, Male 3 Flat Plug"
Thank you for your question. This sensor is intended to be used with our Pro series wideband gauges. It is an LSU 4.2. There is also an LSU 4.9 sensor available that we use on our Pro Plus series widebands. I would check with you manufacturer to ensure you get the correct one.

I need sensor for E85 are there different sensors
Thank you for your question. There are not different sensors for different fuel types, all compatible fuel types, which would include E85, will use the same sensor.
