Hi

I have had my EMS for a few months and been tuning it regularly.
When I was going to do some changes yesterday I always get a message saying that the EMS is offline.

I have checked in device manager for port settings and they havent changed.
I also tried another laptop, usb-serial converter and a computer with a built in serial and I always get the same message.

And my ignition is turned on
My car starts and runs fine

Has anyone ever experienced this issue ?

 

Problem solved by uploading 1.19 firmware again into EMS.
