my car usually idles at like 13.9-14.9 then all of a sudden when i connect my aem ems to my laptop idle goes to like 15.8-16.9

I'm afraid to plug it into the laptop again to try to datalog in risk of blowing my damn motor

also no calibrations were even touched!!! I would have noticed if i accidently changed a calibration by the blinking red message at the bottom left of the screen

 

sounds like a grounding issue


moved any wires recently? are you running o2 feedback?

 

yup he is probably right. where do you have your wideband grounded.

also does the idle get audibly rough?

if not you're probably not really going that lean.

 

yes the idle did get audile rough and i could actually feel the car vibrating, and also i'm not running any o2 feedback yet. Hopefully soon so i can datalog that too...

i'll try again today to see if the problem happens again
