Its just called an eManage, but because its the color blue people call it the EMB or emanage blue. The EMU, or emanage ultimate is black, so that's why they don't call that one the EMB as well + its official name is emanage ultimate.
If you have a standard ECU then the Emanage Ultimate will be the better buy because a)it can raise the rev limiter and b)remove the speed limiter which the lower EMB cannot do. As far as programming you're not going to be able to beat the MINE'S ECU, so basically what you're doing is trimming the fuel levels to match your target AFR (air/fuel ratio). Half the stuff on the EMU is useless to begin with for the average Starlet and 80% of the guys on this site don't use more than 30% of the EMU's ability, so I don't see it being worth the extra money if you already have a good base program like the MINE'S. I do agree you will need dyno time to tune the car and bigger injectors.
