So I just installed boost/oil pressure/oil temp defi BF gauges, they look awesome and work fine, for the most part.

The problem I'm having is with the warning levels of each gauge. From the factory they are set too low and I need to move them up/down, I read the manual and found howto do this and it works, until I turn my car off and then it seems they reset back to the factory settings. Can anyone think of anything I should check for as to why they are doing this? Thanks.

 

i have no clue how those install, but since they are electronic, there has to be a power source.....with that in mind, is there a continuous power hookup, or does the brain unit have a battery backup? if it has a battery, check to see if it is dead

 

There's 4 wires that hookup from the brain unit.

Red : Batter - to 12V battery wire
Orange : IGN - To 12V wire when ignition on
White : Illumination - To 12V wire when small lamp is on
Black : GND - Ground

 

ok, check to make sure your orange and red wires dont need to be swapped....for some reason you are losing all power when the car is cut off.....make SURE whichever wire you spliced the red wire with has a constant 12v source....

 

check your boost gauge and see if it is reading correct.......mine is off by 4psi

 

Yeah it sounds like your constant 12v is not right. Where did you hook it to?

 

mine's dead on..0 bar at idle, around 1.4 at full boost which is what i have my boost controller set too.

 

0 bar at idle....it should be in vacum at idle

 

that what i thought too.......when mine was reading 1.4par i was only running 16psi

 

1.4bar is 20 psi..not sure what you mean.

 

oops..meant 0 when the gauge is turned off..regular vacuum at idle. As far as the boost level, I've had 3 different gauges on it, including these defi gauges, all have read the same readings, the boost gauge is dead on.

 

what is a good place TO hook it too?

 

Bumpage, someone be kind enough to tell me where they grabbed the power lines from ?

 

what i mean is i have two gauges hooked up, when my defi was reading 1.4par the other boost gauge was reading 16psi...........i was missing alot of HP.....now im reading 22psi on my cheap Autometer boost gauge and 1.7 on the Defi.

 

gotcha..the gauge I had on before the defi was reading 19-20psi. And that's what the defi is reading in bars.
