, (Page 1 of 2) State of California AIR RESOURCES BOARD . EXECUTIVE ORDER D—234—3 Relating to Exemptions Under Section 27156 of the Vehicle Code JONES ELECTRONIC TECHNOLOGIES Powertech 6 Pak Chip Pursuant to the authority vested in the Air Resources Board (ARB) by Section 27156 of the Vehicle Code; and . Pursuant to the authority vested in the undersigned by Sections 39515 and 39516 of the Health and Safety Code and Executive Order G—45—5; IT IS ORDERED AND RESOLVED: That the installation of the Powertech 6 Pak Chip manufactured by Jones Electronic Technologies of 7602 Talbert Ave., Huntington Beach, CA 92648, has been found not to reduce the effectiveness of required motor vehicle pollution control devices and, therefore, is exempt from the prohibitions of Section 27156 of the Vehicle Code for 1981 to 1993 General Motors‘ vehicles equipped with a 2.8 to 7.4 liter engine as listed in Exhibit A. . + . This Executive Order is valid provided that installation instructions for the Powertech 6 Pak Chip will not recommend tuning the vehicle to. specifications different from those submitted by the manufacturer. Changes—made to the design or operating conditions of the device, as exempted by the ARB, that adversely affect the performance of a vehicle‘s pollution control system shall invalidate this Executive Order. Marketing of this device using an identification other than that shown in this Executive Order or marketing of this device for an application other than those listed in this Executive Order shall be prohibited unless prior approval is obtained from the ARB. This Executive Order does not constitute any opinion as to the effect the use of this device may have on any warranty either expressed or implied by the vehicle manufacturer. This Executive Order is granted based on results from emissions tests conducted in accordance with Cold—Start CVS—75 Federal Test Procedure. However, the ARB finds that reasonable grounds exist to believe that use of the Powertech 6 Pak Chip may adversely affect emissions of motor vehicles when operating under conditions outside the parameters of the previously prescribed test procedures. Accordingly, the ARB reserves.the right to conduct additional emission—tests, in the future, as such tests are developed, that will more adequately measure emissions from all cycle phases. If such test results demonstrate that the Powertech 6 Pak Chip adversely affect emissions during off—cycle conditions (defined as those conditions which are beyond the parameters of the Cold—Start CVS—75 Federal Test Procedure}, this Executive Order shall be effectively rescinded as of the date the. test results are validated. PFurther, if such test

JONES ELECTRONIC TECHNOLOGIES EXECUTIVE ORDER D—234—3 (Page 2 of 2) results or other evidenceé provides the ARB with reason to suspect that the Powertech 6 Pak Chip will affect the durability of the emission control system, Jones Electronic Technologies shall be required to submit durability data to show that the durability of the vehicle emission control system is not, in fact, affected and/or that the add—on or modified part demonstrates adequate durability. In addition to the foregoing, the ARB reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq. THIS EXECUTIVE ORDER DOES NOT CONSTITUTE A CERTIFICATION, ACCREDITATION, ° APPROVAL, OR ANY OTHER TYPE OF ENDORSEMENT .8Y THE AIR RESOURCBES BOARD OF ANY CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED BENEFITS OF JONES ELECTRONIC TECHNOLOGIES‘ POWERTECH 6 PAK CHIP. No claim of any kind, such as "Approved by the Air Resources Board" may be made with respect to the action taken herein in any advertising or other oral or written communication. — — # Section 17500 of the Business and Professions Code makes untrue or misleading advertising unlawful, and Section 17534 makes violation punishable as a misdemeanor. Section 43644 of the Health and Safety Code provides as follows: "43644, (a) No person shall install, sell, offer for sale, or advertise, or, except in an application to the state board for certification of a device, represent, any device as a motor vehicle pollution control device for use on any used motor vehicle unless that device has been certified by the state board. No person shall sell, offer for sale, advertise, or represent any motor vehicle pollution control device as a certified device which, in fact, is not a certified device. Any violation of this subdivision is a misdemeanor." Any apparent violation of the conditions of this Executive Order may result in its rescission or submission to the Attorney General of California for such action as he deems advisable. The Bureau of Automotive Repair will be notified by copy of this order. Executed at El Monte, California, this ;ZS day of October 1993. Mobile Source Division

validate the emission test results submitted by Jones Electronic Technologies. The Stage 1 Power that was tested in support of the prior Executive Order is incorporated into the Powertech 6 Pak Chip. Its theory of operation is similar to tha£ of the Stage 2 Power. The modifications which are advanced ignition timing andva modified fuel table are oniy active at wide—open— throttle. The towing mode is another option of the Powertech 6 Pak Chip that is active only at wide—open—throttle. Since all the three modes [Stage 1 & 2 Power and towing}) occur only during wide—open—throttle, the emissions impact under the Stage 2 Power and.towing are expected to be the same as the test results of the Stage 1 Power. The othef two modes, valet and anti—theft, could operate during the drive cycle but for reasons of vehicle driveability will not be operated. The economy mode does operate during the drive cycle since the modifications to ignition timing is exercised during part throttle; however, the advanced timing never exceeds 4 degrees which is within the limits mentioned in the "Procedures For Exemption Of Add—On And Modified Parts". Jones Electronic Technologies has submitted all the réquired information and fulfilled the requirements for an exemption.

State of California AIR RESOURCES BOARD EVALUATION OF JONES ELECTRONIC TECHNOLOGIES‘ POWERTECH 6 PAK CHIP FOR EXEMPTION FROM THE PROHIBITIONS OF VEHICLE CODE SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF THE CALIFORNIA CODE OF REGULATIONS by Mobile Source Division 9528 Telstar Avenue El Monte, CA 91731—2990 (This report has been reviewed by the staff of the California Air Resources Board and approved for publication. Approvaldoes not signify that the contents necessarily reflect the views and policies of the Air Resources Board, nor does the mention of trade names or commércial products constitute endorsement or recommendation for use.)

SUMMARY Jones Electronic Technologies has applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their Powertech 6 Pak Chip. The Powertech 6 Pak Chip is a module that contains a programmabie read only memory (PROM) computér chip for installation on 1981 to 1993 General Motors‘ vehicles powered by a 2.8 to 7.4 liter gasoline engine. The 6 Pak Chip contains 6 driving modes for the vehicle to operate: economy, towing, Stage 1 Power, Stage 2 Power, valet, and anti—theft. Jones Electronic Technologies has submitted a completed application and all the required information. Based on the submitted information,and pr;or emission test results performed on a late model 5.7L GM truck with the Stage 1 Power chip, the staff concludes that the installation of Jones Electronic Technologies‘ Powertech 6 Pak Chip will not adversely affect exhaust emissions on the specified vehicles. . The staff recommends Jones Electronic Technologies be granted an exemption as requested and that Executive Order D—234—3 be issued.

i /. EVALUATION OF JONES ELECTRONIC TECHNOLOGIES‘ POWERTECH 6 PAK CHIP 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 Jones Electronic Technologies of 7602 Talbert Ave., Huntington Beach, California 92648, applied for an exemption from the prohibitions of Vehicle Code Section 27156 for their Powertech 6 Pak Chip. The Powertech 6 Pak Chip is a module that contains a programmable read only memory (PROM) computer chip, for installation on 1981 to 1993 General Motors‘ vehicles powered by a 2.8 to 7.4 liter gasoline engine. The 6 Pak Chip contains 6 driving modes for the vehicle to operate: économy, towing, Stage 1 Power, Stage 2 Power, valet, and anti—theft. Jones Electronic Technologies has submitted a completed applicétion and all the required information. II. CONCLUSION Based on the submittgd information and the results from prior exhaust emissions test, the staff concludes that Jones Electronic Technologies‘ Powertech 6 Pak Chip will not adversely affect exhaust emissions from vehicles for which the exemption is requested. III. RECOMMENDATION The staff recommends that Jones Electronic Technologies be granted an exemption as requested and that Executive Order D—234—3 be issued. IV. POWERTECH 6 PAK CHIP DESCRIPTION Many computer controlled vehicles are equipped with an electronic control unit (ECU). The ECU incorporates a programmable read only memory (PROM) computer chip containing the operational data needed for proper engine operation. Engine sensors such as temperature, vacuum, and dxygen are fed directly into the ECU where they are analyzed and compared to the ~1—

theft mode is designed to prevent the flow of fuel to‘the vehicle‘s engine during a start condition. An additional key lock switch is also incorporated into the Powertech 6 Pak Chip package that disables the vehicle‘s starting feature._ Applicable vehicles to the Powertech 6 Pak Chip are listed in Appendix A. v. DISCUSSION OF THE POWERTECH 6 PAK CHIP A 1991 5.7 liter General Motors full size truck wa; used as the test vehicle to evaluate the effect of the Stage 1 Power chip on a prior Jones Electronic Technologies Executive Order. The test program consisted of one (cold start) CVS—75 FTP on the vehicle in the modified configuration. The results of the exfiaust emissions test performed at the Automotive Testing & Development Services are shown in Table 1. Table 1 CVs—75 TEST RESULTS (Automotive Testing & Development Services) HC co NOx (grams/mile) Device 0.33 2.86 0.66 Deterioration factor (D.F.) 1.035 1.026 1.0 Device w/ applied D.F. 0.34 2.93 0.66 Standards 0.50 9.0 1.0 Difference —0.16 —6.07 =0.34 The CVS—75 emissions test résfilts at Automotive Testing & Development Services indicate that the HC, CO and NOx emissions of the vehicle with the Séage 1 Power mode installed, are below the emission standards set for that engine family. The Air Resources Board did not conduct confirmatory testing to —3—
