After setting all parameters and base maps in TunerStudio, it is time to start the engine for the first time. The engine fired up immediately on the first start. The calculated values for the maps are good enough to get the engine running. The maps need to be adjusted based on the AFR (Air Fuel Ratio).
The video below shows the engine running after a few adjustments. The idle control is working, but the RPM is still on the high side. The engine speed is also still fluctuating. Achieving a stable idle speed is done by adjusting the PWM control of the idle control valve and changing the VE table.
More information about tuning the engine will follow later.
