I hope this is not a stupid question. I could not find it discussed anywhere, but it must have come up.

Is there an approved setup for using different firmwares on different cars (or the bench) with the same install of megatune?

I have not tried anything yet, but I have 2 MS2s running 2.3x firmware, and I am thinking about playing with the 2.6 firmware on one of them. I note that the megasquirt-II.ini file is only in the megatune tree rather than the car/project tree where I would expect it.

Maybe there is some magic that makes this not a problem? Or I could just write some batch files to shuffle the files around before starting MT. It just seems like MT should handle this after it asks you which car it is talking to at startup.

Thanks for any guidance.

Make a copy of your car1 directory structure. Name it what you like and configure it for the other car. When MegaTune starts it will present you with a list to select the car you are working on if it finds more that one.

Yeah, do like Phil says, create different 'project' directories by copying the car1 directory (and renaming them to something suggestive like "2.3_pickup" "2.6_fiero", etc.), then copy/rename the appropriate INI file to the project's mtCfg folder. If there's an INI file in the project directory, MegaTune uses that one, instead of the one in the general directory.

So you can have as many codes as you like all running off the same install of MegaTune, and you can have multiple copies of the same code as well by copying the suitable INI file to the various directories. I have many such folders, it works great!

Ah. I already have several "project" directories, but I had not realized I could just put the firmware's ini file in there. I guess it's time to start playing with 2.6.

Thanks!
