boost pressure calculating math formula in IAW

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?

Cheers

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
