The above post is confusing. This statement is not true that "There is no real feedback to the ECU from any sensors."

D-Jet is an "open loop" FI system, receives data (feedback) from its sensors and calculates pulse width to match demand based on that data. A "closed loop" system includes an O2 sensor(s) which additionally monitors exhaust gas characteristics to match demand and is more advanced than D-Jet.

D-Jet cannot really be and is not intended to be 'tuned' per se. The components are 'fixed' to the average owner - its Plug N Play only - so the statement "Once you have assembled the correct collection of parts for a particular "year" than you will be able to tune the system making predictable adjustments" is also not a good characterization. The beauty of D-Jet is its simplicity and that as long as individual components, which can be individually tested, are good, the system works. No 'tune-ups' or alignments adjustments are needed other than the basic engine mechanical, fuel pressure, idle mixture and air mixture settings.
