Tunerstudio can egt connect problem

[MS2tester]

there seems to be a problem with tunerstudio and the can egt?
it sees it during detection but fails to connect to it
either in stand alone or through can!

Check in project properties on the CAN Devices tab, see what CAN ID is set for Main Controller

Make sure that the SERIAL setting in the project properties is enabled.

well i got a little further

in stand alone you should indeed not forget set "serial"
but it would be great if somehow this could be more automated

How can this be automated? There is no way for TunerStudio to know if you have the device connected through the USB port or through the CAN port (through an MS ECU). So you have to tell TS and this SERIAL setting is the way to do it.

i was hoping something like MS2 or MS3 checkes if there is something on CAN
and establisch a CAN chain itself

Looks like you have set your MS2 project to have the ini file for the IO-extender. Using "Detect" will likely fix it.

The problem is that you're trying to get 2 different setups to react the same way but you're telling TunerStudio that they are the same setup. When you create a project for the CAN-EGT only and you connect the PC to it through the USB port, you need to enable SERIAL.

When you use an M2 (or MS3) project and you connect the PC to the MS2 and add the CAN-EGT to this project, TunerStudio will not use the USB port on the CAN-EGT to communicate with it regardless of whether or not you have it connected to the PC. TunerStudio only uses one port to communicate with all the devices in a project so it will use the MS2 serial port and will communicate with the CAN-EGT using the CAN bus. So you need to disable the SERIAL setting for the CAN-EGT. This is strictly a TunerStudio setting and will not affect the CAN-EGT but will tell TunerStudio how to communicate with the CAN-EGT.

So in your previous message, you had solved your issue with a CAN-EGT only project by enabling SERIAL. To solve the issue in your last message, go in the CAN tab in your project properties, select the CAN-EGT in the list of CAN devices and disable SERIAL.

I know this may be confusing but there is also the possibility of using a CAN-EGT only project but using the MS2 serial port. In that case, you will disable the SERIAL setting. And to make things more obvious, you don't want to connect the USB port on the CAN-EGT to the PC.

In theory, it would be possible for TunerStudio to do those things automatically but that would mean that it would have to know all the possible devices that can be connected and how they need to be configured. That becomes complicated and prone to errors and would stop working if something changes. That is why this is in the ini file and it does require you, the user, to set this setting that tells TunerStudio how you have connected things up and how to communicate.

I should add something. I don't know where you got the ini file you used in your MS2 project but from the picture you posted, it seems to be one dedicated to a stand alone setup which uses the CAN-EGT USB port. The normal ini file would not have the "Activated (Default)" value for the SERIAL setting and this would have allowed you to not have this issue.

The default value should have been for a disabled SERIAL setting. That's what the standard ini file has: https://www.diyautotune.com/wp-content/ ... t.ini_.txt

that certainly did the trick
this has become a little clearer to me
i renamed 2 ini,s
one can egt CAN.ini
and can egt standalone.ini
to not forget this
