Hi Everyone,

As many others of the community I too am having problems uploading the firmware on to my MS2 V3. I have tried the solutions posted to others whom have had the same problems but to no avail, unfortunately. I keep getting an error message after 23.1% of loading percentage has been completed. Everything checked out as per the manual up until step 40.

I have attached JPEG pics of the scrolls for the “Windows Uploader” and the “Port Check”. Tunerstudio recognizes the MS2 but obviously says there is no firmware installed.

I normally don’t like to bother other people for help but I am running out of ideas.

Sorry for the mess this is my first post in ANY forum. Thanks for help.

Hi everyone again,

I managed to upload version 2.92 after a little finicking of the file name, but found that when I tested the MS2 with the Stim, the potentiometers for the TPS, IAT, etc. failed to correlate with the Tuner Studio gauges. So after trying to figure that problem out I decided to see if I could upload the latest version, and I successfully did. After the latest version upload everything worked as it should. Just wanted to give you guys a heads up and thanks for the help.

I tried installing firmware for the MS2 V3.0 and this is what I get
