i have a 2nd gen 3sgte swapped in a 1995 celica. i installed an aem digital boost gauge. i have the gauge grounded properly an the positive side is connected to the radio fuse. i tried tapping into to locations to get a vacuum reading. first the map sensor line and second on the timing belt side of the the engine, on the intake manifold. i get wrong readings in both cases. i check the aem pressure sensor and everything checks out fine. any suggestion, or wisdom is greatly appreciated.

but would that cause the gauge to read 22psi at idle?

If your aem boost gauge is like my aem wideband gauge (which I want to sell if anyone is interested) it has a selector switch on the back where you can change the output to the gauge display or to the aftermarket ecu that you are running -------------------- -Jay

there is no selector switch on the back.
i figured it out. i used the ignition fuse for power. i just uninstalled everything and rewired it. everything works now. power has to be constant, because the gauge calibrates itself at each key turn. not sure if im s fan of these gauges.

My aem wideband controller/gauge is the same way. I had it wired to a ignition switched power source and it takes a couple seconds to come on before it shows the a/f ratio, so now I turn it on before I turn the car on. I like certain things about it, but I have my eye on another one that has signal and signal ground output wires for aftermarket ecus. The output of mine is inaccurate without the signal ground. -------------------- -Jay
