I have a defi d boost gauge and a zeitronix(datalogging) and was wondering what would be the best way to hook both up?

 

I tap for boost signal off the vacuum line that goes from the intake manifold to the fuel pressure solenoid. If you want to use that line for both your boost gauge and zeitronix, you can just use a tee.

 

Should I use a tee connector to connect to both devices inside the cabin with 1 vacuum line routed in the cabin and connected to the tee?

 

Do you have a mechanical or electrical boost gauge? I assume the zeitronix will be getting the boost signal off a MAP sensor that's placed in the engine bay. You should be able to route both lines with two tees.

 

The defi-d boost gauge is mechanical, and the zeitronix just needs the vacuum line hooked up to the hose barb. I already have a vacuum line hooked up to my stock mitsu 3 gauge panel, so if I could use a tee on that line into my defi and zeitronix boost sensor, that would make life easier. Im just wondering if that would be a problem as far as accurate readings.

 

Running tees to both the boost gauge and zetronix should be fine. It shouldn't affect accuracy too much. Just try to minimize the line lengths and make sure there aren't any pinches in the vacuum lines.

 

Thanks for your help

 

I tried running 2 boost gauges by T-ing off the vacuum line from the factory Mitsu boost gauge and both gauges didn't work as well. The needles on the gauges didn't react right away, there were delays in both like there wasn't enough vacuum. I put my other boost gauge on the A-pillar though so maybe I had too much vacuum hose. I ended up T-ing off another vacuum line off the intake so both had their own vacuum source and now both work fine and are accurate.
