Islam fouad Posted June 16, 2018 Report Share Posted June 16, 2018 I have link monsoon with 4 bar map internal sensor , i have a problem with its readings , it reads on idle 4.4 psi and when i start to move it increases to 17 psi , btw my boost solonoid adjusted to max 12 psi, 1- I’m connecting a seprated vacum line direct from the intake manifold to the ecu 2- calibrated on zero rpm 3- connecting on analogue volt 5 thanks in advance :) Quote Link to comment Share on other sites More sharing options...
rrob Posted June 17, 2018 Report Share Posted June 17, 2018 Check manifold guage pressure(MGP) or use the metric system. Quote Link to comment Share on other sites More sharing options...
Islam fouad Posted June 17, 2018 Author Report Share Posted June 17, 2018 Check manifold guage pressure(MGP) , how ? already using metric system btw , im not a [rofessional tuner Quote Link to comment Share on other sites More sharing options...

cj Posted June 24, 2018 Report Share Posted June 24, 2018 Looks ok to me. idle is about 30kpa, and under throttle it jumps up to about 180kpa (ie 80kpa/11.6psi of boost). It looks like you're struggling to hold boost at this level though as it tapers off over a few seconds, but your MAP and MGP numbers look accurate. I'd guess that what you are seeing is that the metric>imperial conversion for MAP is working correctly, but its not "normal" to see psi in absolute terms. 30kpa is roughly 4psi, but normally you'd expect to see this as -10.5psi MGP or -22inches of mercury. Remember that 0 psi on a boost gauge (MGP) is 14.7psi absolute pressure (MAP) Adamw 1 Quote Link to comment Share on other sites More sharing options...

Bke36 Posted September 13, 2018 Report Share Posted September 13, 2018 Switch the gauge in pc link from map to mgp and you should see what you're expecting to see I had the same issue (or so I thought it was an issue) Quote Link to comment Share on other sites More sharing options...
