hey peeps got me boost gauge all working today wired it to the fuse board with a add a fuse got it to turn on on the second click but cuts out for a second when engine starts any one no which fuse wont do this 1998 impreza wagon prosport evo green boost gauge

 

Its difficult to do as the starter is drawing all the power from the battery. You could try wiring direct ti battery, but it still might do it during cranking.

 

cant do that as battery is a permanent live and gauge would never turn off

 

You want an ignition live.Take a feed from the stereo or cig lighter with an inline fuse for saftey

 

the raido also cuts for a split second when engine is started tho

 

All cars do

 

Run it through an ignition fed relay.It will still probably die during cranking though Everything dies during cranking except for ecu and starter

 

Maybe a capacitor would help ?
