MS1 extra has 12x12 fuel table vs 2 switchable 16x16 fuel tables on MS2, much higher injector PW resolution on MS2, better idle control options, more coded outputs. Basically more stuff to play with. If you have an automatic transmission with MS1, idle control tuning is a huge pain in the ass. Its doable but takes a lot of work. MS2 is much more intuitive. I don't know anything about MS3 except its out of my budget at this point.

8.1 sec 0-60, 15.8 1/4 with an 8 valve automatic + MS1. At this point the 2.3 auto with MS puts my stock 2.6 5 speed to shame. It actually got me worried that the 2.6 was down on compression but it tested fine. The most obvious benefit is getting rid of the restrictive Kjet fuel meter. Cold starts are instant, throttle response improves even without a TPS and fuel economy is always in the 28-33 range on 87 octane.
If anybody has a stock late model (first gear start) 190e 2.3 auto in the Bay Area, it would be interesting to do some side by side comparisons.
