Questions on flex sensors and tune.
P01 PCM with OS from Tahoe
Never did a flex sensor or flex OS before so bare with me.
When flex is disabled in the tune can you log or will it still show ethanol content while logging but the pcm ignores it?
Had swapped a flex OS , wired up the sensor pigtail but it wasnt plugged it. It defaulted at 37% or so.
I then disabled flex and put ethanol content default at 0. Still reads 37%, the default value even tho I put default to 0.
Then I finally installed the flex sensor with fuel running through it and yet again left the tune with the default at 0 and flex disabled for now. Still says 37%
Although I havent enabled flex in the tune yet (some other issues arose ), would it still do like the oxygen's sensors do where they will still show voltages even if they are disabled?
Or will it only start showing ethanol content when its enabled?
Thank you.
