opinions on EMS's

[integrawhat]

hey all just wandering what your guys opinions on ecu's was. i want something plug and play so i can just plug my lap top in and tune at the track or dyno or even on the road. i want something easy to use and understand but full control of engine and accesories i.e. nitrous and turbo. iv'e been looking at AEM's EMS, but i hear a lot of guys runnin hondata and uberdata but dont know a lot about either system. im looking for experienced opinions thanks guys. oh and does any body know how much a drivesoft system costs and what all it can do as far as engine management.
