I am chasing a connection issue on my ms3 basic. I am hoping that some one here can help.
The car was working fine previously and now out of no where it can't stay connected via usb. I cannot connect to it at all via serial at the moment, although i have never once been able to connect to it via serial (even since new and I've tried on 3-4 different laptops, a few different usb to serial adapters. Sean Church wasn't able to connect to it via serial with his laptop either).
Currently using 22.214.171.124 I have tried 2.08.30 and 2.10.0
1.3.2 (Same firmware I was using before i had issues
USB directly to ms3 basic. I also have the usb to serial FTDI converting from DIY Autotune. I cannot connect to the ms3 via serial.
Symptoms: I can connect to the ecu but it just flashes the protocol error with an error message and the protocol button in the lower right yellow. I get the message "Data write Failed in for 2 attempts. Some recent changes may be lost. Local data refreshed from controller." It connects long enough to pull down the tune and compare differences but will not stay connected long enough to continue forward from there. It just spams error messages at a rate of about 1-2 per second.
I checked the baud rate and the port and re-checked the connection via the Communications -> settings menu. Through the test I can detect the ms3 and test the connection which passes. I have another laptop which I've used to tune/test the ms3 in the past and it also has the same issue.
The car runs on the ecu without issue save what appears to be an un-related issue at a track day over the weekend.
