Finishing up the wiring on my kit today. I wanted to test my ECU to see if my wiring was correct. I turned the key on, the LEDs on the case flashed once, and I configured my port to the settings needed for MS2. When I tried to open Tunerstudios I got this message:

MS2extraRel 2.1.0q was not locally, and it attemped to download it I guess from some place, and said server not available. I didnt save or change anything and tried it with Megatune and got this:

Expected: MSII Rev. 2.88600 (ini file)
Recieved: MS2 Extra Rel 2.1.0q

There was a little more info for each but that was the jist of it.

Is this anything you guys have heard of? Did I hook something up wrong?

Your computer is configured for the standard B&G MS-II code, whereas it needs to be configured for the MS2/Extra code. The error message is telling you your ECU has this MS2/Extra firmware in it, but your computer does not.

Simply download the correct firmware package (http://www.symtechlabs.com/support/knowledgebase/megasquirt:downloads), then run "copyini.bat" to configure MegaTune.

To configure TunerStudioMS, make a note of where the firmware package file you just downloaded is. Then, when you create a new project and TunerStudio asks you for the .INI file, navigate to this folder and select the file titled "megasquirt-ii.ini.ms2extra".

Awesome, Thanks! Im assuming I want MS2 extra from the "Release" section, and the most recent update?

That's correct.

Alright cool, I got Megatune to work good. Tunerstudios is saying theres no connection to the port, and keeps wanting to work offline. So at the very least I can at least use Megatune. I must say though, I saw the gauge layout for TSMS, and I like it as much as or better than MT.

Getting TunerStudio working is really a worthwhile endeavor. MegaTune is quickly losing support and its main developer halted the project.

Often TunerStudio will say it can't connect if anything else is connected at the time. For instance, if you just flashed your ECU using "download-firmware.bat" and the CMD/DOS window is still open, a connection is maintained. Also, if you have MegaTune open, TunerStudio won't be able to connect.

If none of the above cases are true, then go to Communications > Settings and make sure everything is correct. You should have "MS2-Extra," "COM1" (change this to the appropriate number, though COM1 is the preferred choice if you're using a USB-serial adapter), and "115200."

Finally, if you're using a USB-serial adapter, make sure all of your drivers are properly installed and up to date.
