Henkw Posted May 28, 2018 Report Share Posted May 28, 2018 Hi I've selected inbuilt map sensor in anv5 and set to 4 bar but it's staying at 14.5 psi even if I do a calibration when I apply vacuum to the map it goes down fine and also goes up when I put pressure in it but I thought it should start from 0 and work it's way up and down from that value?please help.

Adamw Posted May 28, 2018 Report Share Posted May 28, 2018 MAP is an acronym for Manifold Absolute Pressure. 14.5psi is normal atmospheric pressure. 0psi would be an absolute vacuum and is impossible. You can use the parameter MGP (Manifold Gauge Pressure) if you want to read manifold pressure in relation to the atmosphere. Henkw 1 Quote Link to comment Share on other sites More sharing options...
