I was just wondering if anyone else's MAP sensors read slightly off. I have an AEM 3.5 bar map sensor with the AEM EMS and it reads -.4 when I just have the key turned to the "on" position (the car is not started) shouldnt it read 0. does this really make much of a difference or am I just being paranoid. anybody elses MAP sensors do this??? just wondering


thanks,
John

 

Knoxville Tennessee today is
Pressure: 0.00 in / 0.0 hPa (Falling)
check again tomorrow.

 

it still says the same thing today. it actually flickered for a bit between -.4 and -.6 but then settled to -.4 and stayed there....just curious to if other peoples does this too

 

bump for my quesiton

 

Has it always done this or did it just start? I would have said it had to do with elevation, but you are in Knoxville.

 

nah it has always done this. but it used to flicker between -.2 and -.4 and then settled to -.4 NOW it flickers between -.6 and -.4 and settles to -.4
