Dobeck issues

[Grape Taxi]

Run my Dobeck last year, worked great after getting it figured out, now after having a 590 BB installed ,trying to set my idle zone green, if i set it at 12.5 or 13, it goes up to 15 or 16 , i can only set it at 11 ishh to achieve 13 ish
seams to idle best at 11, at temp
I am missing something, because these numbers differ are my others numbers going to differ as well, just want first ride to be good. Thx for any insight

I'd think you'll have to make some minor adjustments to the green and yellow zones with a big bore install, they need to be tweaked with extreme temp and elevation changes too. Your transition ponts and red zone should not need any changes. At least it's really easy to make changes!

Red zone is Closed loop. So the needle will directly correlate with the air fuel desired when adjusting. The Green zone and usually yellow zone are not closed loop. So when you adjust the gauge in green its not on scale. Just move green, let the gauge reset, see what the AF is and reference from the sensor read. Not what # the needle is pointed at
