Transition Fuel Trim: After activating staging you can trim +/- 2048us injector pulse width to both injectors
Rate to primary injectors: Same size = 100%, Smaller secondary stage = lower number, larger injectors = higher number, 630 primaries with 1680 secondary = 266%
Example:
number of Primary injectors = 4, Rate to Primary Injector Size = 100%, injector 1 pulsewidth = 10ms when staging not active,
after activating staging injector 0 and 4 pulsewidth will be 5ms
number of Primary injectors = 4, Rate to Primary Injector Size = 200%, injector 1 pulsewidth = 10ms when staging not active,
after activating staging injector 1 and 5 pulsewidth will be 3.33ms
Thresholds: Secondary stage is activated when both TPS and MAP thresholds are exceeded.
