what calc pids do i need to set up to use an autometer wideband gauge to log analog into the v2 so i can do calc.vet tuning. can anyone help me make a pid list.

Autometers are programmable.
We'll need to know the programmed Lambda/AFR range.

im new to this stuff so what do you mean by programmed lambda/afr range

The slope & intercept are needed in order to convert voltage to afr or lambda.

Example:
4 volts = 20 afr
0 volts = 10 afr
stoich afr =14.7
voltage from WBO2 = 1.88

(20-10)/(0-4) = 2.5 (slope)
0 volts = 10 (intercept)
(1.88*2.5)+10 = 14.7

Preferably you want to know the programmed Lambda slope & intercept because
any stoich AFR value can be converted from that.
