If autoadaptation is active but it is not desired in certain ranges of engine operation, it is possible
to deactivate such ranges in the autoadaptation process. Select an area of the map with a mouse and
click the right button after selection. A context menu with “Autoadaptation lock” and “Autoadaptation
unlock” commands is displayed. Locked areas are marked with grey correction values.
Controllers for 6 and 8 cylinders (STAG-300 QMAX PLUS) offer two MAP correction maps, one
for each bank. The maps can be switched only with B1/B2 buttons under the map clearing button
.
If the “Auto stop” is checked in ISA3 autoadaptation mode, areas with successful
autoadaptation will be locked automatically.
2.20. OBDII/EOBD reader
STAG-4 QBOX/QNEXT PLUS and STAG-300 QMAX PLUS are equipped with an integrated
reader of parameters and faults based on the OBDII/EOBD interface. It is not necessary to connect an
external adapter
– all required circuits are integrated with the controller board.
The tool supports the following standards:
ISO 15765 (ext. std. 250/500Kbits)
– commonly referred to as "CAN”;
ISO 14230 (5Baud, Fast init);
ISO 9141
– commonly referred to as “K-line”.
The reader is initiated by selecting the “OBD reader” option on the gas settings tab. If the
controller operates in auto mode, it will attempt to connect to the OBDII/EOBD diagnostic system upon
activation of the ignition switch.

The reader window can display maximum 7 parameters at the same time. Navigation is realized with
buttons
, which are used to scroll through the parameters read via OBDII/EOBD. For showing
or hiding the parameters of OBD reader on the oscilloscope in the application use the button
.
The button
opens the parameters configuration window (Figure 49), which allows creating any
sets of displayed parameters thanks to which it is possible to display a set including only parameters
that are required for system calibration (such as fuel loop status, STFT and LTFT trims, results of
a wide-band oxygen sensor). The window displays a set of 96 parameters available in OBDII/EOBD
