There are "lite" versions of the tuning software (Tunerstudio MS and MegaLogViewer) which have the core functions for free. Unfortunately the full-featured free software Megatune isn't supported for any of the newer firmware versions, so if you want things like autotune you'll probably want to shell out the money for Tunerstudio at a minumum. MegaLogViewer's full version is certainly nice to have, but the autotune feature is good enough that you don't really need the extra features it provides. Tunerstudio's full version is $60 and MegaLogViewer is $30. The free versions won't restrict the ECU itself, but the auto tuning feature is worth the money in saved time.
MS1 and MS2 have serial ports, so you either need an old laptop with a serial port or a generic USB-serial adapter. I'm using a USB-serial adapter, I think with a Prolific chipset. It's pretty old and the new recommendation is one with an FTDI chip instead. They're cheap and not at all specific to Megasquirt. I was having bad disconnect issues that I think stemmed from the low speed of the Prolific chip. The disconnects ceased when I limited it to 25 reads/second down from 50, though I also switched serial cables at the same time. The issue is fortunately fixed and I was able to get a few 50,000+ record logs recorded today.
Tomorrow morning I'll be working on my brakes more than tuning so I should be able to get some full bike shots and take some time to post screenshots of the tuning software and some of the settings I've used. While the bike was stripped apart I took the opportunity to unlink the front and rear brakes and run steel braided lines to the front calipers. I don't think it bled fully because they still feel awful.
