Quick LC-1 question

Is megasquirt preprogrammed for a 0-5v (7.35 - 22.33 afr)? Or is it 0-5v (10 - 20 afr)?
My lc1 is outputting 0v for 7.35afr, and 5v for 22.33 afr. Is this correct? Or should i change it to 0v -> 10, 5v -> 20??
Just wanted to make sure I'm not tuning my car innacurrately.

I have my LC-1 doing 0 - 5 = 10.0:1 - 20.0:1

Megasquirt itself isn't programmed for anything, It works on target voltage, which can be anything. It has no idea what AFR its shooting for. Megatune turns the AFR you enter into a voltage which it sends to megasquirt. So what I'm saying is its megatune that needs to know the range, and this is in the settings.ini where you'll need to select the range that corrosponds to what your sensor does. Most use
#set INNOVATE_0_5_LINEAR "Innovate, PLX 0-5V 10-20:1 AFR"
(this is for ms1, ms2 may be different)

I meant defaults.
Thanks Jon, I'll change it.
