So ECS installed their kit on my car yesterday, everything went really well, loving it so far even though the weather is shit right now. I know they did a 3 bar map sensor but my Interceptor gauge isn't reading boost, it's stuck at 29.xx' vacuum reading. I thought with a 3 bar MAP sensor the PCM would see boost thus gauge would read.

Am I missing something?

odd I can read boost fine with my torque pro app on my phone. The gauge toggles between vacuum and boost.

[FrostySS]

Right, that's what I thought it did.

There's nothing extra to hook up or wire in on a 3 bar MAP sensor right?

[KingLT1]

nope

[FrostySS]

I'll email aeroforce

It legit doesn't change at all when I'm on the gas. I haVe it set on the manifold pressure display where I assume it would show vacuum then switch to boost when in boost. I'll shoot Aeroforce an email.

When I first got my setup I bought their little Boost Signal 5v device that attaches to the little Vacuum T off the intake and then had to run a signal wire to the back of the Aeroforce gauge.

Once I got the 3bar map from Ted I was able to remove that first device. I know have 2 Vacuum items on my Aeroforce. One was the original first device and now there's like a native OBD Boost/Vacuum.

Not that any of this really helps you but just wanted to point out how mine was an analog plugged in to the back of the gauge to now a native one just in case you did something similar before.

They just emailed me back, apparently I still need to run wiring, I ASSumed that it could be read through the OBD2 port since there was a 3 bar MAP sensor installed but I'm wrong.

I don't really need the boost gauge, I might buy the dual pod on the dash and just run a dedicated boost gauge, not sure yet.

I thought that the boost reading was always just a calculation.The OBD2 reads the Barometric pressure and the MAP. Then, MAP-Barometric = boost.
but hey, I could be wrong...cuz i'm only going by the what the internet told me.

[FrostySS]

Can anyone else chime in? Aeroforce is saying it's in the tune, my tuner saying it's set up...unless I'm on the wrong setting on the gauge I'm lost lol

I have it on the manifold vacuum/boost read out on the gauge. Should I be showing something else? I have it run just through the OBD2 port, no other sensors or connectors hooked up on the back.

[Dysan911]

When you ran through the setup of the Aeorforce. The actual "Setup" menu item. Its where you can put an * next to the items you want it to read. Is the boost/vacuum one enabled or do you see any that seem to regard the MAP sensor?

[FrostySS]

Yes. Apparently I still have to run a wire to 5v on the map sensor and plug it into the analog slot on the back of the gauge. I assumed with a 3 bar it would just read boost through the OBD2

I do NOT have anything setup like that on mine. Mine does read boost natively through the ODB2. It didn't until my tuner sent me the 3 bar Map sensor. Once he setup my tune to read that new map sensor the vacuum/boost was avail natively.

[FrostySS]

What readout do you have your gauge set on to read boost is it the manifold pressure that switches from vacuum to boost?

[Dysan911]

This is mine. When running it will read vacuum and the roll into boost as I get into the throttle
