OK, real close but still issues.

Tried to open MegaTune, got:

ERROR:megatune.ini:0051-The included file "custom.ini" could not be opened.
MegaTune Terminating

Tried to open TunerStudio and got:

Unable to access jarfile TunerStudioMSLite!.Jar

Tried again and got it to open, Started new project ...

Yes, The latest version of the Firmware has been installed. So I assume that I need the Boot Jumper off and after loading TunerStudio I would Power up the MS 2 and it will detect the .S19 file and load the correct .INI file? Is that the correct order or should the MS 2 be powered up when the program ...

I looked at that yesterday and will go that way. I will remove all programs loaded first. I did not see the order, do I load the program, then power up the MSII with the stimulator? How about the boot jumper, It needs to load the .S19 program first? Thanks for your patience.

OK, after playing with the USB/Serial Port driver I got success on the communication. Thought I was home free. Put matching .ini file in CAR1 and opened configurator to activate, but after highlighting the INI file Activate is greyed out so I cannot activate.

I will try again tonight on the XP computer with COM1.

My friend, an experienced EE, built the board and succesfully loaded the Firmware (Monitor_v2.892abs.s19 with no issue on his XP laptop with serial port.

Any ideas on what I can try on my Win 7, USB Laptop. That is the one I will be using for ...

The above is with my laptop, USB and Windows 7. I cannot communicate with Downloader or Megatune.

I have a desktop with XP and a serial port and get this message while trying to communicate with Download (boot jumper on for Download):

Matt, I'm pretty sure the Port (Comm 3) is not the problem. I Uninstalled Downloader and Megatune from my computer and reinstalled. When I right click the .ini file and save target as, and try to save it to my car1 file I get megasquirt-II_2892.txt couldn't be downloaded.
I downloaded it to my ...

I have not been able to get communication between the MSII V3 and my laptop (Windows 7 USB with adapter) or desktop (XP with serial port). Jumper is off. Our EE buddy who built the board added the missing jumpers, got connection and loaded .S19 program.

I loaded and ran the Hypertherm program and ...

Yes, Jumper over 2 pins. 7.8V at stimulator, not great but should communicate.

Got a little further but getting this error message:

I have a similar communication problem. I haven't used MS in about 5 years and getting re-aquainted. I am helping a friend with a Magnasson Blown 383 in a 1953 Chevy PU. Board has just been built by an electrnics friend and is untested. When I put the 9V battery on the stimulator only the PNP light ...
