ok I see how your working out the psi now,
I think ?
the ecu reading is in absolute pressure in Kpa
your x8 converts to mmhg
then convert this to psi
take off attmosperic which leaves boost
I was mistakingly using 14.7psi as 1 bar not 14.5
I think the conversion from Kpa to mmhg is x7.5 not x8
I think an easier convertion is simply x the absolute figure in bar by 14.5 then take off atmos at 14.5
so 211 gives
2.11 bar
x14.5 = 30.595
-14.5= 16.095psi
