Hi all,

I'm new to the site, I am trying to tune my 2014 Honda MSX.

I've searched and found some relevant threads:

viewtopic.php?f=57&t=24431

But it seems that the software by RyanHope/puffthemagic is now only available commercially through MCU innovations: https://mcuinnovations.com/software/hondaecu/

There are several forks of the original work on github but compiling them from source into a windows executable is beyond me (I have tried lol)

There is also a similar tool in Hondaflasher but this site has no downloads or instructions to buy. https://hondaflasher.webnode.fi/

So my question is, is anyone still working on this open source? Is there anyone out there with an older version compiled into a windows .exe they can share?

I know enough about the mapping side but this python coding/building stuff is not my area.

Thanks.
