My car has a SAFC II installed it in. I did not do it the original owner did. I was just flipping through it last week to see what it logs and just the general operation of it. I have no "tuning" skills on an SAFC but I am very familiar with dsmlink that I have in my GST. Well I was in the "sensor type" area and I accidently switched what it was reading and it almost died and my CEL came on. well I THOUGHT I switched it back to what it was but I'm just not sure. Bc the last week or so I've been having a "rough" idle. It doesnt miss but its not steady. I guess what my question is, The sensor type now is reading "karman." Right above karman is pressure. Should it be reading karman or pressure? I'm not sure if its "ok" to switch what its reading.

Thanks for any help in advance!

Karman is short for karman vortex aka mass air flow where pressure refers to cars that run with speed-density or a MAP sensor. Karman is the setting you need.

 

Ok thanks for the help I appreciate it
