Default Two Easy ?s Possibly

Okay here it goes, First off Is the fuel pressure in MS accurate? And It seems that I cant get my MLV A/F to match what my gauge says, any ideas? I have them both set to LC-1 default? And when I change the LC-1 output to 0-5v It still isn't right I'm confused, at idle it seems my gauge matches MS but when I look at MLV it shows my A/F in the 11's at WOT when my gauge shows 12's

Um considering you don't even have a fuel pressure sending unit connected to MS, no it is not accurate.
If you change the LC1 to linear in MLV and MT then you need to hook up the controller and change it in there are well. Should be 0-5v 10-20 AFR.
You have to use the same settings in all 3: Controller, MT, MLV.
