I just upgraded to MSExtra 3.1.1 and was trying to upgrade the settings in the controller
using MegaTunix but some options had values that were wrong.
Shown in the table below are some of the ones I noticed.

(option)	TunerStudio	MegaTunix

Multiply MAP	multiply	Don't Multiply

Injector Staging	Alternating	(blank)

Incorporate AFRTarget	don't include AFRTarget	Include AFRTarget

Also, some of the sensor calibrations did not work properly.
For the coolant temp sensor value at 5.0 volts it refused to accept any value greater than 32.7.
In contrast, for the wideband AFR calibration it worked fine with a preset setting (AEM 30-230x).

And shown below is a partial output of the log.

Prompting user for ECU family to interrogate...
Command "c" (MS2 Clock), returned 2 bytes
Command "A" (MS1 Runtime Vars), returned 169 bytes
Command "Q" (ECU Revision), returned 20 bytes (MS2Extra Serial310 )
Command "S" (ECU Signature), returned 60 bytes (MS2/Extra release 3.1.1 20110304 20:55GMT (c)KC/JSM/JB MS2)
Detected Firmware: MS2-Extra V3.1.0 series

I suspect these may be configuration issues with the new 3.1.1 firmware version.
