LSU 4.2 Pressure dependancy

A pressure change of the measured gas gives a deviation of the sensor output signal of:
I_P(p) = I_p(p₀) * p/(k+p) * (k+p₀)/p₀
The factor k is dependant on rich (lambda < 1.0) or lean (lambda > 1.0) and is for the measuring gas from LSU test bench described in section 4.2 )(Bosch document *) :
k_lean = 0.47 bar
k_rich = 0.39 bar
