This is a discussion on Boost gauge (T-less?) within the Interior Mods forums, part of the Tech & Modifying & General Repairs category; I'm new to the turbo scene so bear with me I have a 2010 WRX and have been scrounging around ...

    Boost gauge (T-less?)

    I'm new to the turbo scene so bear with me I have a 2010 WRX and have been scrounging around the web looking at boost gauges. Is it possible to get one that doesn't require tapping into the boost line?

    Correct me if I'm wrong, but doesn't the Cobb Accesport provide boost measurements in real time? This would indicate to me that the car has a built in pressure sensor monitoring boost pressure - surely there's a boost gauge out there that monitors the built in boost pressure sensor so that I don't have to add possible leak paths to measure a pressure that's already measured !?

    You can use the readings available to the ECU, via the OBDII connector. A few devices do this, and those that do should also allow you to see other data available to the ECU. I have not seen anything in "gauge" format though - but am open to suggestions - rather, in "gizmo" format (square box like what Cobb and others sell etc.).

    I think those would make for a rather expensive boost guage. I would have thought there'd be an off the shelf electronic one that taps off the factory sensor - I guess not SPT boost guage it is then (unless I get the Cobb Accessport first, which is also on my list)

    I think there was one called the scantool or scangauge or something. Search around for "OBD gauge" etc and you should find several. There are also applications for laptops and mobile devices.

    Here's a small device, for example:

    No relationship with site and not a recommendation, just an example. No prior experience etc.

    The beauty of a vacuum line tapped boost gauge is you can monitor more accurately the pressure and spool through the sweep of the needle (assuming you use an analog interface).

    Boost can also be monitored for free via opensource (eg romraider). The parameter is manifold absolute pressure (corrected) I believe.

    Why not install one? The risk ofactuall leaking from a gauge can be prevented with the correct fittings.
