yeah looks a bit lean. I found my e30 out lof the box on moronic was similar, at about 13.8:1 throughout. I've had some trouble with my LC1 being accurate, to confirm that the LC1 figures are spot you really need to get her on a dyno.

I wouldn't go off of a OEM narrowband.. Like said above, get it to a dyno to get some more accurate wideband readings.

he's not using an OEM narrowband but an LC1 wideband. Still same applies, I was disappointed with how far out mine was when I went on the rollers. I need to recalibrate, check wiring and take megasquirt out of the equation (I was viewing values in megatune) then retest.
