Sensor Calibration adjusted and engine is sloppy.

[rgr-2000]

I m using the HFS-5 and the system is properly setup and runs fine.

The car is EVO7.
Water is triggered at 1.4 BAR.
pure water.
Jets are 0.5 , 0.8 and 0.9 mm.
Injectors 1,150cc.

At DDS3 dash:
WL is set at proper position.
WH is set to full clockwise.

Days ago I unintentionally adjusted the sensor calibration (SC) turning knob on the DDS3 dash to full clockwise. The engine was bogging when water was injected (1.4BAR). The ECU map stayed the same and did not switch to safe map at that time (knowing this coz I installed a map status light). I tried this several times. Same results.

Then I turned the SC back to where it should be. The car was back to normal driving under boost.

As I know , the SC has no effect on water amount injected.

What's the possible cause??
What does the Sensor Calibration (SC) effect?? Anything other than just the bar graph on the dash??

The only thing I did is adjusting the SC and it s gone bad.

Thanks,
