I just got MegaSquirt running on my 401; I did a lot of research over the past few years and MegaSquirt looked like the best option for me.
The only downfall is that you have to know what you're doing, and it takes a long time to understand and tune (plus soldering together the ECM takes time if you opt to go that route). But that's just my kind of system! I love challenges.
So far, MegaSquirt hasn't been nearly as bad as the naysayers have made it out to be; I just think they didn't do their homework first. My installation went smooth as silk and it fired up on the very first click of the key.
