I used to be really into MS back in the day - I was one of the first to run an MS3 kit when it came out, I built MS1/MS2 PnP setups before it was even a thing, etc. My M20 still runs MS3 (mostly reliably), but honestly - I've been playing with OEM computers for the last 5 years or so, and I don't think I could go back.. at least, not on something that wasn't a complete toy/science experiment.
After several years of constant tweaking just to keep it from driving me crazy (I daily drove with it for years, all 4 seasons, as my only car), I just could never do that again. There are some things, like startup, coast down, and idle, where the OEM computer 'just works' that you will almost never get right on something tuned from scratch. Sure, people will say theirs is fine - but I doubt many people here have put anywhere near as many miles or driven in as many conditions on Megasquirt as I have, so I don't really buy it.
I've been working on a BMW tuning platform for the last two years - currently the oldest I support is MS45. I'd love to support these old Motronics but there's only so much time in a day..
