MAF and Boost guage.
MAF and Boost guage. Hey,
How does the Boost guage work in conjunction w/ the MAF sensor. I was told when someone changed out my old MAF that my boost guage picked up a couple of inches of vacuum. Now I only have about -6 to -8 inches and am trying to figure out if I could have fried the MAF sensor or what could be the problem. Thanks guys.
Also, if you know anything about Vacuum sources, I seem to gain a few more inches of vacuum when I disconnect the "T" portion that is running into my AC system. Is that normal or could there be a fault in my system drawing a lowering vacuum showing on my boost gauge.
If anyone needs further explanation, I do have pictures but I don't know how to post them up.
Thanks,
Justin

the a/c system creates more of a load on the motor.
as far as i knew the MAF sensor and the boost gauge don't work together. The MAP sensor detects the manifold vacuum by kPa and if you have the factory MAP then it maxes out at 103.x but i see 104kPa on my efilive.
as far as i know a boost gauge doesn't work with the MAF...you can calculate boost your gettin based on your MAf reading of g/s

also man, your STS numbers, is that on the stock block with bolt ons @5psi?? i'm wondering what numbers I will put out on mine. I have bolt ons (all u can do w/o going internals)
That's on 8 psi...
So I could have a leak in my AC system? I might have someone that works on the AC go check that out. I don't think I'd be able to understand what I'm looking at when it comes to the AC.
And, we're going to go w/ the general understanding that a good or bad MAF will not effect my boost reading. hmm..

I understand that, but if they know what they are doing w/ the whole AC system I would hope that would also mean they know what they are doing w/ the vacuum side of things too. :-\ Thanks again, Dustin. I'm not trying to be a pain.

Verdad Gallardo Well, I said screw you to the line running to the AC and clipped it off. Now I'm seeing almost 19 inches of vacuum, where I've only seen -14 before. The car runs like a champ right now. I know there are flaws that I'm going to need to work out, but I took her out on the road and let me tell you. Ah, I missed that feeling.
