I was looking at my pressure readings on my V-AFC and at idle it reads about -600 to -550 but at full throtle it jumps to +4 to +6.
I have asked other people that have V-AFC's and they told me that their readings never go into the positive. They say that at WOT their reading are like -42.
Does anybody elses V-AFC read in the positive or am i the only one??
Is it a bad or a good thing???
If its bad how do i fix it??

please help!!!! ....thanks

 

the highest i've ever heard it either at 0 or +1

 

Anyone install their own Vafc? how hard is it? Any problems? thanks

 

I installed my own. I had no problems,just make sure you follow the diagram correctly and when you splice the wires you make sure they are connected properly

oh ya and make sure you do the preset-up before you turn the car on. you dont want the v-afc thinking your car is a 6 cyl.

 

I have had 0 or +1 one a handle full times. It was when I dropped 2 gears at like 40-60 mph and took off. I thought it was cool, cause positive manifold pressure is boost.

 

so you are saying the higher the manifold pressure the better....correct?

i was just wondering ,cause no one else i know says that thier pressure goes into the positive and i was wondering if I maybe had a vaccum leak or something.

 

The positive pressure is some what normal. My brother could get +3 or 4.

As far as a vaccum leak it is just the opposite. If you had a leak you would be in the negatives.

 

Thanks for clearing that up for me.
