BOOST gauge

Has anyone installed one before? I know they are typically for turbo cars but I know some of you are running higher boost than stock.

Sure When I purchased a zeitronix zt2 wideband and dashdaq setup I also got a MAP sensor. I had it installed on the passenger side surge tank and ran the wiring through the firewall to the ZT2 control unit which then feeds the dashdaq. I datalog quite a bit, so I wanted to get as many parameters directly from the engine or ECU instead of going through the painfully slow OBD2 port.

Any pics of just the boost gauge installed so we can get an idea of what one looks like in AMG?

The gauge or the sensor? The gauge is displayed on a Dashdaq XL, and is configurable. I don't have a pic of the installed sensor atm, if you would like I can post a pic once I get the car back from my fabricator.

I'm talking about a boost gauge that senses vacuum. I want to know where you tapped the supercharger for vacuum.

All apologies, I confused the two. I don't have a boost gauge installed. Though I believe boost can be logged through the OBD2 port. Or if you datalog with a MAP sensor subtract 14.7.

Yeah monitoring boost via an electronic signal is not the best way. A boost gauge ported to a vacuum source on the supercharger is the best way.

There are no unused ports that see boost on the 55K motor. You must drill and tap POST SC otherwise your reading vacuum only
