i recently bought a apexi avc-r of one of my friends the only thing was i only got the avcr headunit and boost control solinoid. at the time i didnt know that i was missing the engine bay harness and the pressure sensor. anyway i got a pressure sensor from the greddy revec5 i hooked it up and started the car. at idol it reads -500mmgh the when i go full it reads +o.15. i dont have the turbo on yet. anyway i just want to make sure this pressure sensor is working properly.
is there anyway of changing any setting to lbs instead of bar?
id be very thankful for anyhelp on this one

 

need help im sure there's a alot of people on this site using the avc-R. i pretty need to know what the boost gauge is show at idol
