Note : The target boost pressure map is above atmospheric pressure. Example : if your atmospheric pressure is 0.86 bar and you want to have 0.5 bar boost the target would be 0.86 + 0.5 = 1.36.
Note : Closed loop is only possible if a map sensor which can read the boost up to or more than your boost target is wired into the SMT8L.


Note : The SMT8L boost control cannot reduce the boost to lower than the canister rating. To check the exact boost PWM use the data display and display the boost PWM as a large or small number.
