aem boost gauge sensor location
 

I currently have the aem sensor mounted in the manifold, about half way between the throttle body and the left intake ports. Most of the time it doesn't read correctly, and occasionally it does. I took the analog gauge housing apart and mounted the gauge in a custom multi gauge housing. AEM hasn't been all that helpful. I did the tests and confirmed it's wired correctly. This is their analog gauge.
My question, is there a better place to mount the sensor than the manifold.

Maybe a pic of your present set-up?

The aem sensor is yellow.

You can tee into the brake-booster line in the frunk. Good signal and makes for a very short and simple wiring run.

This is in a bus. I confirmed the gauge and wiring are fine according to the aem trouble shooting section. Since I didn't use their installation kit I'm wondering if taping directly into the manifold, or manifold location is the problem. I also may have damaged the gauge. AEM doesn't sell just the gauge, so I would have to buy the whole kit again. I'd like to rule out everything else before I do that.

I just pulled one of these from my 930 last night, in favor of one of AEM's FailSafe units. If yours turns out to be bad, contact me. If I haven't already sold it through the F/S section you can save a decent amount of money by picking up a proven used one (I've used it for about 2K miles) for much less than new.

pm me a price. It might be worth it to have an extra gauge.
thanks,

Test you sensor and gauge with regulated compressed air, if it holds nice and steady it's probably the location.

It's an electronic gauge.

Pull your sensor and use air pressure at the sensor opening with power to it and watch your gauge.

Hate to cost myself a sale, Harold, but you should still be able to test it by applying metered air to the brass sensor/fitting. If it doesn't check out it could be either the gauge or the sensor. If, however, it passes the test you'll just need to identify a different mounting point.

Edit; I need to work on my typing skills, as the same suggestion was made mere moments before my post ...

The gauge reads inconsistently. A few times it reads correctly, then not. Sometimes it sets at 0 at idle, sometimes not. Yesterday instead of showing boost, it showed vacuum.
Norm, your set up will let me swap out stuff to check.
I don't see what there is to test on the sensor.
