EVALUATION OF CUSTOM CHROME‘S REVTECH PROGRAMMABLE DIGITAL IGNITION SYSTEM FOR AN EXEMPTION FROM THE PROHIBITIONS OF VEKHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. ~ INTRODUCTION Custom Chrome of 16106 Jacqueline Court, Morgan Hill, California 95037 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code (VC) for the RevTech Programmable Digital Ignition System, part no. 59—770, for all 1995 and older Harley—Davidson motorcycles equipped with the 1338 cc engine, except those equipped with a factory fuel injection system. II.‘ CONCLUS IONS Based on submitted emissions test data, the staff concludes that the RevTech Programmable Digital Ignition System will not adversely affect exhaust emissions from the Harley—Davidson motorcycles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Custom Chrome be granted an exemption for their RevTech Programmable Digital Ignition System for all 1995 and older Harley—Davidson motorcycles equipped with the 1338 cc engine, except those equipped with a factory fuel injection system. The staff also recommends that Executive Order D—368—4 be issued. IV. IGNITION SYSTEM DESCRIPTION The RevTech Programmable DiQita] Ignition System has been specifically designed for installation on Harley—Davidson motorcycles equipped with the 1338 cc motor. The ignition system operates in conjunction with the original equipment manufacturer‘s (OEM) fuel delivery system along with the emission control system a]readyvcertified with the stock engine. The primary purpose of —1—

the ignition system is to enhance the motorcycle‘s overal} performance by modifying the OEM ignition timing curve. The RevTech Programmable Digital Ignition System also has a built—in rev. limiter and a firing mode select. The RevTech Programmable Digital Ignition System has been designed to allow the Harley—Davidson owners the ability to.configure the ignition system to match their own requirements. With four preprogrammed timing curves installed, the Harley—Davidson owner can adjust the ignition system to accommodate fuel grade, air temperature, and engine hardware. Table 1 list the conditions that work best with each pre—programmed ignition curve. Table 1. Advance Curve Description Curve 1 Stock engine, cool air temperature, or high octane fuel, this curve brings up the advance earliest and to the highest final vailue. Curve 2 Slightly modified engine, warmer air ' temperature, regular grade fuel, this curve brings up the advance a little slower than curve 1 to prevent detonation on near stock motors. Curve 3 Performance engine, high compression, poor quality fuel, hot air temperature, this curve is good for built motors that tend to detonate, advance comes in slower than curve 2 and to a lower final value. Curve 4 High performance engine, high compression, poor fuel quality, hot air temperatures, this curve should only be used if your motor still detonates using curve 3, advance is brought in still slower and to a lesser final than curve 3. In addition to the adjustable timing feature of the ignition system, it also includes a rev. unit select and a firing mode select. The rev. unit select allows the rider to either maintain the factory 6000 rpm rev. limit or switch to a 6500, 7000, or 7500 rpm rev. limit. The firing mode select allows the rider to choose either a dual or a single spark mode. —2—

v. DISCUSSION OF THE IGNITION _SYSTEM A 1989 Harley—Davidson with a 1338 cc engine was used for the evaluation _of the RevTech Programmable Digital Ignition System. Emissions testing was conducted by Compliance and Research Services, Inc. of Linden, New Jersey for Custom Chrome, and consisted of eleven Cold Start CVS—75 emissions tests on various modified configurations. The ARB did not pefform emissions tesfing to confirm the test results submitted by the applicant. A summary of the test results is shown below with DFs applied: Exhaust Emission Test Results Exhaust Emissions (gm/km) # of Plugs Spark Mode HC Co 4 Single Fire Curve 1 0.504 3.712 4 Dual Fire Curve 1 0 .648 3.967 4 Single Fire \Curve 2 0.582 3.769 2 Single Fire Curve 2 0.811 7.310 4 Dual Fire Curve 2 0.835 3.244 2 Single Fire Curve 3 0.679 4.129 4 Dual Fire Curve 3 0.607 5.199 4 Single Fire Curve 4 0.642 4.962 2 Single Fire Curve 4 0.672 5.261 4 Dual Fire Curve 4 0.711 5.882 2 Single Fire Curve 4 0.572 5.261 Standards 1.0 12.0 Results from the emissions testing conducted at Compliance and Research Services, Inc. have demonstrated that the installation of the ignition systefi does not cause tailpipe emissions to exceed the applicable emission standards. fherefofie, based on the test results, the staff concludes that the installation of Cugtom Chrome‘s RevTech Programmable Digital Ignition System, will not have an adverse effect on those applicable motorcycles. Custom Chrome, Inc. has submitted all the required information and fulfilled the requirements for an exemption. —3—
