D electronics monitor engines RPM and processes a stream of information inputs from the throttle position and engine temperature sensors.  From these inputs the  D  system automatically changes, adjusts and modifies the fuel delivery to maintain the fuel curve.  Further refinement of the fuel curve is possible by adjusting the knobs on the ECU.  The payoff for all this electronic capability is excellent start up, driveability, power and economy. D Pro-jection is designed to be used on stock, or mildly modified engines with at least 15-inch vacuum at idle (A\/T idling in gear).\u003cbr\u003e\u003cbr\u003e\u003ch5\u003eSpecifications:\u003c\/h5\u003e\u003cbr\u003e\u003ctable class=\"descr-table\" border=\"0\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_ASC\u003c\/td\u003e\n\u003ctd\u003eHolley Performance Emission Code 5: This part is legal for sale or use on Emissions Controlled Vehicles; Uncontrolled (Non-Emissions Controlled) Vehicles; and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DEF\u003c\/td\u003e\n\u003ctd\u003eComputer Aided Design Software\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_DES\u003c\/td\u003e\n\u003ctd\u003ePro-Jection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_EXT\u003c\/td\u003e\n\u003ctd\u003ePro-Jection; 4 DI MPFI w\/E-Prom;\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_FAB\u003c\/td\u003e\n\u003ctd\u003eE-Prom Chip\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_INV\u003c\/td\u003e\n\u003ctd\u003eMPI; AUTO; EPROM DISKS SERV PT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_LAB\u003c\/td\u003e\n\u003ctd\u003eProposition 65\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_MKT\u003c\/td\u003e\n\u003ctd\u003ePro-Jection 4DI MPFI E-Prom\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDescription_MKT\u003c\/td\u003e\n\u003ctd\u003ePro-Jection D electronics contain a basic performance fuel curve that has a wide range of adjustability.
