My avcr boost display reads -28mmhg intead of 0.00kg with ignition on engine not running.Any ideas how to calibrate to display 0.00?

 

There's nothing that I know of for calibration. I THINK you can pick different sensors in the Etc. menu - make sure the "stock" sensor is selected if so.

Might also want to make sure the grounds are properly installed. There are 2 ground wires, and they need to be attached to the same ECU wire with one closer to the ECU than the other. A flaky ground could cause an error in reading.

I believe mine shows 0 with the engine off.

Thanks Dale, yeah picked Relative 1 on sensor settings thats whats recommended
on manual but no good. Its not out by much, guess i can live with it,works fine anyways

 

i dont think it is meant to read 0 when not running mine doesnt and when running it still doesnt read 0 i have done a fir bit of work to my car and if there was a problem with it we would know
