Injector Staging SettingsTransition 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 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 0 pulsewidth will be 3.33ms
Thresholds:
Secondary stage is activated when both TPS, MAP and RPM thresholds are exceeded.
