Ok, to tidy up my bay I got a vacuum distribution block. I tapped in to the brake booster vacuum hose. my question is:-

1, Can I use that source for my 3 bar gm map sensor? [if I'm right isn't there some sort of check valve in that manifold port?]
2, Can I use that for my boost gauge?
3. Can I use that for my greddy boost control solenoid [the NC port] ?

 

anyone?

 

i know it all comes from the same source- but is it a good idea to tap into the brake booster line?

 

my preference would not be to use the brake booster hose also, although its probably alright.

i also like to have the MAP sensor on its own line, as its kind of important. i'm willing to compromise, but i basically want the signal from the engine to the MAP sensor to be as precise as possible.

it the boost gauge was electronic (has its own map sensor), then i'd tee it with the ECU's map sensor.

i'd run the boost control separate.

 

Use the locations the stock ECU would use!

 

alright, ya I'm using mechanical boost gauge too.
