avoiding the question? or just miss it?
Well, i'm not sure that i can give a great answer here....
However, having seen the Smarty and played with it, as well as reading up on it and talking to a friend who has the SSR tuning ability for his truck - That there really isn't a very good way to compare.
I'm of course an EFILive fan and beta tester for the Dodges, so my answer will probably come across biased which I don't want...
However, the SSR still seems to allow 'whole table' modifications in that, from what i've read and heard - you pick a # (say 1-20 or whatever) for your timing, then for your rail pressure, etc... You really don't have an idea of what is different from 1-20. There are i'm sure finer grained settings as well, however - EFI let's you view every cell of these tables (Timing, Pressure, Pilot, Main, Post, etc.)...
This is a bit of a gross analogy, but let's say that you know that at roughly half throttle and 2400-2800 RPM your truck surges because of turbo, or too much fuel, or whatever.... EFILive lets you go adjust JUST that part of say your fuel pressure table (making an assumption that logging has showed this is where the problem is, instead of just a wild guess which you'd have to do with ANY other tool on the market for the Dodge's). In short, you can isolate and dial in just the problem areas of the fuel pressure table (say 50-70 mm3 @ 2400-2800 RPM) to smooth them out, drop pressure, raise pressure, etc...
Again, my example is poor. The important points are that you can:
1- Data log your truck to find out what its doing (as part of owning an EFILive V2 cable)
2- Fine tune the rough spots to exactly what you want/need within the physical capabilities of the truck.
Let me know if i did a horrible job explaining here and i'll try to do better later tonight.
