Engine management?

whats the best out there for DSM's? Dsm Link sounds great but its costly, AFC is cheaper but does it do as much? or how about one of those total management systems like greddy emanage

If you think dSMlink is costly for engine management, youre in big trouble if you look at the laternatives ;) AFC and dSMlink can not be used in the same conversation. Two different things entirely. The AFC will get the job done, but after you buy the AFC, logger, and ECU chip, you've spent more than you would on DSMlink ;) Mine paid for itself when I sold all the half assed parts it replaced.
