Default a/f read out

so the new software version has an a/f ratio... how accurate is this?

my car is down right now, but the new software looks awesome.

i believe it's getting the AFR reading from the front o2 sensor, which isn't that accurate, and I believe it stops around 11.xx.

For a better, more accurate afr reading, get a real wideband

At WOT mine drops to a SOLID 11. I would guess its useful only to see if a lean condition exsits (kinda)

If you are going to change your A/F. You should not use the stock narrowband o2 sensor. It is not sensitive enough for tunning. Do some searches on it.
