What are the advantages of the newer Commander series TBI over the older Pro-jection?

Real time programmable, you tune it while you drive. Much more control over all parameters such as accel enrichment, cold start etc. Similar to FAST and Accel in most ways.

The TBI uses GM delphi injectors and has a progressive throttle linkage.
