Datalogging Screen

QUICK INFO

Use this screen to help you tune the PID control settings when using the feedback boost control mode.

It will only be available when the feedback control is enabled in menu 4.2.

How to use:

• If the LOG is empty, data-logging will automatically start as soon as boost is over +30kPa / +0.3bar / +4.4psi.

• The data-logging will automatically stop as soon as 127 samples are recorded. It runs at half the solenoid frequency so for a solenoid frequency of 20Hz the recorded

     length will be 12.7sec.

• To clear the data and be ready to log again, just hold the center button pressed for a few seconds.

• To review the recorded data press the "ENTER" button to go to "REVIEW" mode.

Data will be displayed at the bottom of the screen from the sample at the cursor position.

"tgt"  target boost in kPa

"map" actual boost in kPa

"rpm" rpm at cursor position

"sol" actual solenoid duty cycle at cursor position

"p" progressive duty correction at cursor position

"i"  integral duty correction at cursor position

"d" derivative duty correction at cursor position

On the top right corner of the screen the recorded lambda value at the cursor position is displayed.

The boost representation on the display is relative to the target boost, so the boost target line will always be straight, even if you have set the target boost to vary with rpm.
