boost pressure calculating math formula in IAW

[arjunior45]

hi guys,

does anyone know the mathematic formula to calculate the boost pressure from the values in the "westgate duty cycle" map of the OEM file?

Hi nick ,
You dont calculate pressure from duty cycle ,I think ..

ok, from where in a eprom could i understand the max boost that gives in the Q4 {max allowed boost or max stationary boost}? and which is the formula?

sorry my ignorance.

I just want to confirm what I said in my e-mail yesterday:

p(abs) = hex/hFF*250 = boost-map-value(n)/255*250 [kPa] where n probably is 400:400:6000,6500 rpm
