I keep getting a reading of - 1.1 psi MAP from my SEC monitor even with the engine not running (just power on). Is this a ground issue maybe? I just bought a new 3 bar MAP sensor and still the same. Also the monitor is set correctly to 3 bar.
I also have a spa boost gauge and it reads 0.0 at the same point and I get 26.1 max boost with that and only 21.0 psi on the SEC Monitor.

Anyone else with anything like this?

 

Anyone?

 

try contacting Simon directly by Email, im sure he'll shed some light on it....

it's quite normal to have a small offset like that with the map sensor
