Tell me please can I swap marelli 3bar MAP to any other brand 3bar MAP(apexi, greddy, ....) to use st3 chip whith it? Couse - I can't find it in my city.
I know that they all give 0-5V to ECU and have linear dependence from pressure. But greddy and apexi is not interchangeable because they have different shear of linear dependence concerning 0V and 5V, and for example at 2V it means different pressure.
