I’ve been studying the new engine management system from Holley. The first items I’m going to get and test is a backup for every sensor. I would feel very silly to travel 600 to 800 miles to race and have a problem with a $30 sensor.
If two identical air temp sensors vary 3 degrees would I need to change the offset to make the ECU supply the engine with identical A/F and spark of the previous run?

Now that I’ve thought about it a faulty O2 could cause all kind of headaches.
