FORD INTERCEPTOR DOWNSTREAM ENGINE MANAGEMENT SYSTEM FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF c REGULATIONS I. INTRODUCTION Crane Cams, Inc. of 530 Fentress Bivd., Daytona Beach, Florida 32114, has applied for an exemption from the prahibitidns of Vehicle Code Section 27156 for their Ford Interceptor Downstream Engine Managefient System {(Interceptor) for installation on 1990—92 Ford Motor Company Mustangs, sold in California under AB 965, equipped with a 302 (5.0L) Y—8 gasoline engine. Crane Cams has submitted a completed application and all the required information, as well as exhaust emissions test data performéd at Crane Emissions Laboratory and E.C.S. Laborato;ies, Inc. II. CONCLUSIONS Based on the submitted information and the results of the emissions tests performed at both laboratories, the staff concludes that the installation of Crane Cams‘ Interceptorlwi]l not adversely affect exhaust emissions from vehicles for which the exemption is requested when tested in accordance with the Cold Start CVS—75 Federal Test Procedures. III. RECOMMENDATION | The staff recommends that Crane 6ams, Inc. be granted an exemption as requested and that Executive Order D—225—20 bé issued. IV. DESCRIPTIONOFTHEFORDINTERCEPTOR The Interceptor is Qpecifically designed for installation on 1990—92 Ford Motor Company Mustangs that are equipped with a 302 (5.0L) V—8 gasoline engine. The Interceptor is an electronic programmable controller, designed to enhance the vehicle performance without interfering with the emissions —1—

related functions. Certain features of the Interceptor extend the capabilities of the stock control system in the areas of performance and security. | The Interceptor is comprised of three components: an engine controller, a hand—held data terminal, and a wire harness. The ancillary items include a cable to connect the hand—held terminal to the controller and an OWnerIOperator Manual. The hand—held terminal has two windows, allowing access to a LCD display screen and a 20—key, membrane—type keypad for data entry and command selection. The hand—held terminal weighs 280 grams. The wiring harness consists of ihrée connectors and bundles of individually insulated wires covered Qith a protective loom. Two of the connectors mimic those found 1q the stock ECU/Vehicle harness junction. The third connector plugs into the three components modular connector on the controller. . c The Interceptor is installed between tfie stock»ECU (Electronic Control Unit) and the vehicle harness. Of the 44 signél lines present between the vehicle harness and the stock ECU, 20 lines are passed throfigh. 15 lines are monitored, and 9 lTines are intercepted.' "Passed through" means that a given signal line is connected directly from the vehicle harness to the stock ECU without interruption or contact with any other circuit. "Monitored" means that a given signal is unaffected. "Intercepted" means a given signal could be modified. The Interceptor can modify two basic signals: fuel injector pulses and spark out. The fuel injection pulses are modified in three ways. During operation below the factory rpm limit, injector pulse widths may be modified to provide more or less fuel. The second mode of fuel signal modification takes place during what will be termed "extended rpm operation" beyond the —2—

stock fuel cutoff speed. The third way of modifying fuef pulse signals is shutting off the fuel pulses when a user chosen engine speed is reached. Adjustment limits for fuel‘can be set at a maximum of + 24 percent from base setting. The spark out signal is the command sent to the Ford ignition module which then produces a spark. Adjustment Nimits for timing can be set at a maximum of + 20 degrees from base setting. Yariable driving conditions will not allow the use of a fixed minimum and maximum value for fuel injector pulses and spark out. This is why the Interceptor uses a progressive or regressive implementation table which allows the vehicle to operate without experiencing driveabiIify problems. This imp]eméntation table will only allow the vehicle to se;‘specified values which the manufacturer has determined will not affect vehicle driveability even if the minimum.and maximum values are preprogrammed. See Appendix A for implementation va]des. ‘ The Interceptor also provides the user }nformation about the operation of the engine and the operation of the Intercebtor itseIf. These functions display data on the LCD screen when the Interceptor is in the “mgnitor mode." The engine information functions displaythe current values of engine speed (in rpm), throttle opening (in %)., oxygen sensor state (R or L), fuel pulse duty cycle (in %), and total spark advance (in degrees). These data items are updated with a frequency of about 10 Hz (10 times a second), and thus reflects essentially "real—time" values. | The Interceptor provides user interface through the LCD display and keyboard of the hand—held terminal, and.software which directs the user‘s inputs and reports the status of the Interceptor. There are three modes of operation: system setup, monitor, and data set editing. Setup requires initial inputs of engine cylinders, type of air flow measurement (Mass 3

Air/Speed Density), and injector scheme (bank/simultaneous/sequential). The monitor allows the user to view real—time values of important engine control signals. Ohce the interceptor is programmed with the necessary system setup data, the monitor mode becomes the default screen during normal vehicie operation. Data set editing allows the user to make adjustments to any of the three available data sets without destroying previously saved data. v.— THE A 1991 Ford Mustang (AB 965) powered by a 302 CID engine was used for the evaluation of the Interceptor. Emission tests conducted by CEane Emissions Laboratory consisted of four cold—start CVS—75 emission tests with the Interceptor installed on the test vehicle. The four cold—starts were used by Crane and ARB to determine worst case emission parameters of the Interceptor. The résults were evaluated against the emission standards as demonstrated in Table 1. Table 1 CVS—75 TEST RESULTS (Crane Emissions Laboratory) HC £0 NOx Emission standards 0.41 3.4 1.0 #1 +24% fuel —20 degrees spark 0.18 2.00 0.47 #2 —24% fuel +20 degrees spark 0.15 0.29— 0.78 #3 +24% fuel +20 degrees spark 0.20 2.35 0.57 #4 —24% fuel —20 degrees spark 0.13 0.39 0.61

The ARB also required Crane fo conduct two additional CVS—76 emissions tests, test #2 & #3 as described in Table 1, at an ARB recognized independent laboratory. Véhicle exhaust emissions in the two modified configurations were compared with the applicable emission standards. These results are shown in Table 2. Table 2 CVS—75 TEST RESULTS ECS Laboratories, Inc. HG cQ _ NQx Emission standards G.41 > 3.4 1.0 #1 —24% fuel +20 degrees spark 0.21 0.33° 0.86 #2 +24% fuel +20 degrees spark 0.22 1.26 Q0.77 Difference #1 | ~0.20 —3.07 —0.14 Difference #2 — —0.19 —2;14—-0.23 Both CVS—7§ emissions test results at Crane Emissions Laboratory and ECS Laboratories, Inc. indicate that HC, CO and NOx emissions of the vehicle with the Interceptor insta1led,afe below the emission standards. This demonstrates that the installation of the Interceptor for 1990 to 1992 Ford Mustangs equipped with a 302 CID (5.0L) V—8 gasoline engine will not adversely affect exhaust emissions when tested in accordance with the Cold Start CVS—75 Federal Test Procedures. | Crane Cams has submitted all the required information and fulfilled the requirements for an exemption. The test results confirmed that Crane Cams‘ Interceptor meets the requirements for the exemption. —5—
