Inferred octane

I have 2 inferred octane channels. One reads 95.9 the other 91.0.

Can either be trusted?

Ok, I added a can of octanium the first channel went from 95.9 to 98.3. So I believe it works. However the second channel remains at 91. Anyone know why?

Also this goes to show Costco gas is not subpar, their 93 reads as 95.9 on my mustang. This in a reformulated fuel market.

This depends on your setup of tables for accuracy

I'll flash the stock tune and see if it changes.

What tables are you referring to?

With the stock tune channel 2 still remains at 91 channel 1 started at 95 and kept climbing the more I drove. It was at 96.3 when I bounced the rev limiter and said screw it, went back to my tune.
