Pretty sure Ive ran into this a couple times, dealing with the NTK newer AFRM. If you pull it up, then just select AFRM in transforms in very one Ive been brought, it reads off air fuel logged being higher than displayed on the device.

In their instructions its says that AF16 mode is default, which shares same scaling as Ballanger AFR500 default and NGK AFX transform. If you just look at an AFRM, and select AFRM in transforms that is actually setup for the AF20 mode which is not default for AFRM. Could these be relabled maybe say "NGK AFX, NTK AFRM - AF16 (Default)" and " NTK AFRM - AF20 (Selectable)"

Save me alot of headache because I get these maybe 3 a year and have to scratch my head before I remember it out again and I dont have much hair left
