I originally thought this was a MSDroid problem, posted here: https://www.miataturbo.net/megasquir...gnature-83401/
Then I realized my computer won't connect either. I've now tried MSDroid on 2 phones and Tunerstudio on 2 computers. This is after it worked flawlessly for the last year or so. I bought all new cables; new serial cable, new serial to usb for the computer, and new usb to mini-usb for the phone. None of which would work.
I opened the megasquirt up but nothing looked obviously wrong so I put it back together. Is there anything I can try or should I start begging one of our MS gurus to save me? Anyone had this problem before?
*Edit - FWIW, the ECU still works, the car drives fine, just had a few issues in the tune I wanted to work on.

I'm using a serial to USB adapter. The one I normally use was from you guys (DIYAutotune). I tried another one that I'd used in the past, not sure where it came from but neither would work so I assumed that wasn't the issue.

I assume this is what you're talking about, if not let me know.

I uninstalled/reinstalled the usb adapter and checked the settings to make sure they were at 115200.
Thanks so much for the help. I really appreciate it.

Sorry, I need you to use a different program - it's here: http://www.diyautotune.com/downloads.../portCheck.zip

Braineack built the megasquirt for me and loaded the firmware so the answer is "I don't know." I'll give it a try and report back. I assume the newest available is what I want? Thanks.

I finally got a chance to mess with the car, so I'm back here begging for help again.
I downloaded firmware, installed the boot jumper, and tried to reload the firmware. The great news is that I'm getting a connection, the bad news is I'm too dumb to figure out how to load the new firmware.
When I run the loader I'm getting these prompts and I'm unsure how to go further:
![](https://www.miataturbo.net/attachments/megasquirt-18/137564-megasquirt-wont-connect-firmware1.jpg?dateline=1428705101)
The readme file says to open Tunerstudio and it should detect and automatically install the correct file, but it does not (or I'm doing something wrong). I was unable to manually install the firmware through Tunerstudio as well. When I try to "Detect Device" under project properties I am getting a message that no Firmware is installed.

Again any advise is greatly appreciated and I offer infinite apologize for my ignorance.

Matt, thank you so much for the help. I got the new firmware loaded and tunerstudio connected right up with no other issues. This is actually the 3rd megasquirt I've bought from you guys. Hopefully I won't need another one anytime soon, but if I do DIY will definitely be my first stop.
