Stand-alone engine management?

[rhock99@epix.net (Ryan H)]

Are there any stand-alone engine management systems available for a 16v?   I'm looking for one that controls spark and timing advance, maybe via the knock sensor, coolant temp. sensor, hall sender, throttle switches, plugs, etc.  
I'm sick of the problems with my knock system, and plan on adding a turbo in the future, so it would be nice to have a SEM system to learn until then...  Thanks.
