Application Note : AN 1.6 |
Introduction
The SMT8 has electronic boost control. This application will show you how to wire and configure the boost.Purpose
SMT8 Boost Wiring

SMT8 Boost Setup
There are 4 main boost maps. Low throttle position PWM vs RPM. High throttle positions PWM vs RPM. PWM vs Air Temp. Boost Target AMP vs RPM. Select the setpoint you have chosen for boost control in the setpoint map.

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 : The SMT8 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
