EVALUATION OF HKS USA, INC.‘S HKS ELECTRONIC VALVE CONTROLLER (EVC & EVC II) FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS I. INTRODUCTION HKS USA, Inc. of 20312 Gramercy Place, Torrance, California 90501 has applied for an exemption from the prohibitions in Section 27156 of the California Vehicle Code for the HKS Electronic Valve Controller (EVC & EVC II). The HKS Electronic Valve Controller (EVC & EVC II) is designed for installation on 1993 and older model—year OEM turbocharger equipped passenger cars. HKS USA, Inc. has submitted data from comparative emission tests conducted on a 1985 Ford Mustang SVO equipped with an 2.3 liter turbocharged engine at Automobile Club of Southern California, Los Angeles, California. II. CONCLUSTONS Based on the results from comparative exhaust emission tests performed at Automobile Club of Southern California on a 1985 Ford Mustang SVO equipped with an 2.3 liter turbocharged engine, the staff concludes that HKS USA, Inc.‘s HKS Electronic Valve Controller (EVC & EVC II) will not adversely affect exhaust emissions from vehicles for which an exemption is requested. III. RECOMMENDATION The staff recommends that HKS USA, Inc. be granted an exemption for their HKS Electronic Valve Controller (EVC & EVC II) for installation on 1993 and older model—year OEM turbocharger equipped passenger cars.

IVv. DEVICE DESCRIPTION The HKS Electronic Valve Controller (EVC & EVC II) is designed for installation on 1993 and older model—year OEM turbocharger equipped passenger cars. The HKS EVC consists of two main components: the under hood control valve and the cockpit mounted control module linked by a wiring harness. The control valve houses a multi—step solenoid valve and pressure sensor. The cockpit mounted control module houses a microprocessor which, utilizing the control valve pressure sensor (port #1 — see Appendix A), samples the intake manifold pressure. Using this data, the microprocessor operates the control valve‘s solenoid valve. The solenoid regulates the pressurized air drawn (via port #2) from the discharge plumbing of the turbocharger. This regulated air is discharged from port #3 to the wastegate actuator controlling the wastegate action. According to the manufacturer, by closely controlling the wastegate action, the maximum boost pressure and boost response curve is optimized to increase power for a given application within the constraints of the OEM fuel injection system. The EVC & EVC II are identical with one exception: the EVC II does not incorporate the manual boost control and "volume" knob. Both units have Off, Low and High settings which, according to the manufacturer, allow a range of boost levels permitting safe operation of the vehicle in less than ideal weather as well as increased performance. V. ELECTRONIC VALVE CONTROLLER (EVC & BVC II) EVALUATION AND DISCUSSION A 1985 Ford Mustang SVO equipped with an 2.3 liter turbocharged fuel— injected gasoline engine was used for the evaluation of the HKS Electronic Valve Controller (EVC & EVC II). The dynamometer inertia weight and loading used were 3500—lbs and 8.9—hp respectively. —2—

Comparative emissions tests conducted by Automobile Club of Southern California for HKS USA, Inc. consisted of one Cold—Start CVS—75 emission test in the unmodified (baseline) configuration, followed by one Cold—Start CVS—75 emission test in the modified (Electronic Valve Controller (EVC model) installed) configuration in the manual mode with the volume set to maximum. The Air Resources Board did not perform tests to confirm the test results submitted by the applicant. A summary of the test results is shown below: Exhaust Emissions Test Results On A 1985 Ford Mustang SVO Test Exhaust Emissions (gm/mi) Mode EC co Nox Baseline 3.01 18. 32 2.80 Device 2.61 18. 22 2.89 Difference —.40 —.10 +. 09 % Difference —13.25% —.53% +3.25% The differences between the device emission test results and baseline emission test results submitted by the applicant were within the allowed limits of .1 gm/mile HC, 1.0 gm/mile CO and .1 gm/mile NOx as specified in the "Procedures for Exemption of Add—On and Modified Parts." Therefore, the installation of the HKS Electronic Valve Controller (EVC model) did not have an adverse effect on exhaust emissions on the test vehicle. Due to the ability to manually control the maximum boost pressure, HKS USA, Inc. supplies a recommended maximum boost pressure for each application. These recommended boost pressures exceed the OEM maximum boost pressures. According to the HKS USA, Inc., they tested various vehicles at these increased pressure levels and found no decrease in engine durability. The ARB did not perform any durability testing at this time and reserves the right, in the future, to request further documentation of the durability effects of —3—

application of this device. HKS USA, Inc. submitted all the required information and fulfilled the requirements for exemption.

NOTICE: This manual assumes that you have and know how to use the tools and equipment which are necessary to safely and efficiently perform service and installation operations on your vehicle. This manual also assumes that you are familiar with typical automotive systems and terminology and basic service and repair procedures. DO NOT fiempt to carry out the operations described herein unless these assumptions are rect. ays have access to a factory service manual as many of the procedures and specification required for the proper installation of this product will be referenced to the shop manual. To avoid the risk of personal injury to yourself and to others, and to avoid the possibility of damaging your vehicle and rendering it unsafe, follow the safety precautions contained in the factory shop manual for the vehicle you are working on. INTRODUCTION: The HKS EVC (Celectronic valve controller) provides immediate selection of up to four preset manifold boost pressure selections or variable manifold boost pressure control from within the vehicle cockpit. The HKS EVC incorporates two main components, the control module and the control valve, which are linked only by electrical connections. No hoses are routed through the firewall and into the cockpit. USER NOTES: Before increasing the boost pressure on your vehicle, read through the entire manual and familiarize yourself with the terms used herein. Pay special attention to the following precautions. 1. The HKS EVC System is available in two styles for the following applications: Be certain to choose the right unit for your application. Swing Valve Type: For integral wastegates (most OEM style wastegates) with single pressure port actuators. Popet Vailve Type: For remote, dual pressure port wastegates (racing type) and for integeral wastegates with dual pressure port actuators (HKS turbo system). 'The purpose of the HKS EVC is to increase the boost pressure accurately and eliably, but most factory turbocharged vehicles also have a secondary boost limiting system to control the boost pressure in case of wastegate or wastegate actuator failure. Due to this secondary boost control system, the HKS EVC will not be able to raise the boost pressure above the point at which the secondary boost control is activated. 3. When using the HKS EVC, know the limits of your vehicle and engine. Pay special attention to the following. * Increasing the boost pressure may cause detonation (knocking, pinging>). Detonation can cause severe engine damage. 4. Increasing the boost pressure (intake air volume) may require additional fuel volume to the engine. Make sure the engine has the correct air/fuel ratio and the correct ignition timing to prevent detonation. 5. The HKS EVC unit will not lower the boost pressure below the original setting. 6. The HKS EVC is a very precise electronic component. The unit should be handled with extreme care to avoid possible damage. The HKS EVC components must not be exposed to extreme heat, water or dust. Make sure the unit is wired properly before operation. TEMPERATURE RANGE: CONTROL UNIT —25 Deg. C to 77 Deg. C ¢—13 Deg. F to 170 Deg. F) VALVE UNIT —25 Deg. C to 100 Deg. C (—13 Deg. F to 212 Deg. F) 7. The HKS EVC cannot control boost pressure above the maximum efficiency point of the turbocharger. Additionaly the HKS EVC will not be able to compensate boost pressure loss due to turbocharger size. 8. Increasing the boost pressure will also increase the intake air temperature. IFf the intake air temperature is above 210 F <100 C), performance increases may be minimal and detonation may occur. . Increasing the boost pressure will shorten the combustion process. Due to a hortened combustion process, the ignition timing may require retarding. 10. Use 92 or higher octane fuel. The use of 92 or higher octane fuel may reduce the possibility of detonation. 11. DO NOT rely on the factory boost gauge or the bar graph boost gauge on the HKS EVC when adjusting the maximum boost pressure. Install an accurate auxillary boost gauge to moniter manifold boost pressure levels. — 1 —

1. MANIFOLD PRESSURE SENSOR PORT The manifold pressure sensor port is attached to an uninterrupted intake manifold pressure source. This manifold pressure‘signal is utilized by the EVC control module to make corrections in wastgate valve opening lift and duration to maintain accurate manifold pressure levels according to the selections on the control module. ONTROL VALVE PRESSURE INLET PORT Pressurized air, drawn from the compressor housing or the intake air pipe, is routed through the control valve pressure iniet port prior to being modified (by the sclencid valve housed within this chamber> according to the selected control module setting. 3. CONTROL VALVE PRESSURE OUTLET PORT From the control valve pressure outlet port, constantly modified pressurized air recieved by the control valve pressure inlet port is routed to the wastegate actuator. This accurate, aven pressure maintains accurate wastegate action resulting in stable maximum boost levels in any gear and almost any elevation or atmospheric condition. 4. BLEED OFF PORT Control valve pressure inlet port #2 will recieve the pressurized air from the turbocharger or intake air pipe. The pressurized air is modified and excess air is bleed off through the hole. When mounting the valve unit, make sure the hole is not plugged and that it is pointing down.
