I don't want aftermarket gauges in the car. And I hate having dead gauges in the dash. So I want to get the gauge working.

Anybody ever work this out?

 

Im on a mobile device and I posted this in the wrong section. Can a mod move or delete this thread?

 

Thread moved per your request into the Engine Management Forum.

To make the stock boost gauge read is a matter of isolating its signal, finding the end points of its full sweep and then running it through its range with a calibrated pressure source using a TII boost sensor (or other source of input voltage with pressure/voltage scale known), ECU and cluster.

This is the sort of thing that my Universal Gauge Sender was made to do.
