Table 1
Recommended Inlet Manifold Pressure    
Engine RPM     Inlet Manifold Pressure (1)    
900    
40 5 kPaa (5.8 .7 psia)    
1000    
50 5 kPaa (7.3 .7 psia)    
( 1 ) kPaa is kilopascal measured in absolute pressure.These recommended values are provided for reference only. Parasitic loads affect the required inlet manifold pressure. The engine choke trim can and should be adjusted to a manifold pressure level that provides the optimum engine stability and the load acceptance capability for the specific application of the engine.Electronic Choke Trim Procedure
Set the engine operating condition to the rated speed and no load (or minimum load possible).
Connect the DDT to the Engine Supervisory System (ESS). Display the DDT screen "number 33" by pressing the "SELECT MODE" key
