I was also considering upgrading to the new firmware since it has some better options.
0) I can't find the old megatune so that I can read the MS ECU!!! Can I do it somehow with the new megatune??
You want to get the release version of Megatune. Its the 2.25 version. Use this with the new stable firmware code 029q2. You "should" be able to "read" the old code using the MT configurator, it has the ini file for the 021 series of code in it, and then you can create a new .msq file to transfer to the new code, if you wish to use the new 029q2 code. The Megatune configurator is a software program that has many of the stable code's extra.ini files in it, so you can "activate" that particular firmware version with MT, using the program, so you dont need that old MT version you are looking for. Once you open the MT configurator program, read the help files on how to use it. Basically, the release version of MT 2.25, is compatible with the older firmware codes. The MT configurator program makes is easy to activate whatever firmware code you want to use with megatune. Hope this makes sense..
1) How do I get the current settings/fuelmaps/sparkmaps off the megasquirt now to back it up?
Once you install the release version of MT, and run the configurator program, activate the 021 code series. Then, connect your MS, and open up MT, and it should read your MS and all its stored settings. Then, to back it up, click file, then save as, and name your new .msq file.
2) Will I lose all the tuning if I upgrade the firmware?
No you shouldn't, but you will see many new features and settings from 021u3 to 029q2. I would go through each and every setting and double check EVERYTHING. This is very important. If you decide to upgrade to 029q2, first save a fresh .msq file for your current settings. Run MT(after you have configured it to read the 021 code), and then click file, then save as, and name your new .msq file. Now once you have downloaded the new code to your MS, configure MT to read the 029q2 code by using the extra.ini file in the 029q2 zip file, then open up MT, power up your MS, and then hit file, open, then find your saved .msq from 021 code. You may get a error message or two, but burn that to your MS, then go through all your settings to verify them. Once you are all done, file, save as, and name your .msq file. Now you have a new 029q2 msq file.
3) Should I just find the old megatune and just tune with that??
You will gain many nice features if you upgrade to the latest MT and 029q2 firmware. If you still have the old MT version .exe install file on your old computer, you can find that, copy it to a cd-r, then use that to install on your laptop, or by means of a network transfer between computers, if you know how to do that... Hope this helps you a bit anyway.
