About this app

Used to log a configurable set of PIDS in mode 22 or 3E to assist in ECU flash tuning using the popular Macchina A0 (or DIY clone) and our free firmware:
https://github.com/Switchleg1/esp32-isotp-ble-bridge.

Found us on Facebook:
https://m.facebook.com/groups/926154161803291/

Additional features:
-Long click on any active gauge will reset min/max values on all gauges.

-Long click on "Quick View" will load into a full screen mode displaying the first 8 gauges on the current tab.

-Gauge styles can be set individually using the tab field.
Examples include:
||
Default|ROUND|0 - this will force this PID to display as a round gauge on the default tab and place it in the top left corner of the tab.
Airflow|BAR_H - this will force a horizontal style view on the Airflow tab.

-Logging will take place once all conditions in the logging equation have been met. Example: "c>0|r>1000|d>70" - logging will start if cruise control is enabled, when RPM is above 1000 and when pedal position is above 70%.
