Turbo charger controlled by ECU is being applied recently. ECU calculates the optimized fuel ratio by measuring the accurate air mass from turbo charger.
If the boost pressure from intake manifold reaches target pressure value, ECU makes a part of exhaust gas bypass.
Concentrated mix gas makes much higher horse power in explosion cycle.
ECU shows DTC when wastegate sensor voltage at closed position is out of range.
