                           EXECUTIVE ORDER 0—234
                 Relating to Exemptions Under Section 27156
                            of the Vehicle Code

                       JONES ELECTRONIC TECHNOLOGIES
                              PERFORMANCE 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;

11 1S ORDERED AND RESOLVED: That the installation of the performance chip
manufactured by Jones Electronic Technologies ("performance chip") has been
found not to reduce the effectiveness of required motor vehicle pollution
contrel devices and, therefore, is exempt from the prohibitions of Section
27156 of the Vehicle Code for 1987 to 1991 model year General Motors truck
applications listed in Exhibit A, which is attached hereto and incorporated
herein.       *

This Executive Order is valid provided that installation instructions for
this performance chip will not recommend tuning the vehicle to
specifications different from those submitted by the device 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 Air Resources Board.  Exemption of a kit shall
not be construed as an exemption to sell, offer for sale, or advertise any
component of a kit as an individual device.

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 CYS—75 Federal Test Procedure.
However, the ARB finds that reasonable grounds exist to believe that use of
the performance 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 emissica tests, in the future, as such tests are
developed, that will more adequately measure emissions from all cycle
phases.   If such test res®its demonstrate that the performance chip
adversely affects 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.   Further, if such test results or

                                *                 (Page 2 of 2)




other evidence provides the ARB with reason to suspect that the performance
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 BY THE AIR RESOURCES BOARD OF ANY
CLAIMS OF THE APPLICANT CONCERNING ANTI—POLLUTION BENEFITS OR ANY ALLEGED
BENEFITS OF JONES ELECTRONIC TECKHNOLOGIES‘S PERFORMANCE 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 untrus 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.

     EVALUATION OF JONES ELECTRONIC TECHNOLOGIES‘ PERFORMANCE 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 Avenue, Huntington Beach,

CA 92648, has applied for an exemption from the prohibitions of Vehicle Code

Section 27156 for their Performance Chip for installation on 1987 to 1991

model year General Motors trucks listed in Appendix A.     Jones Electronic has

submitted a completed application and all the required information, as well

as exhaust emissions test data performed at Automotive Testing & Development

Services on a 1991 5.7 liter Chevrolet full size truck.

II.   CONCLUSIONS
      Based on the submitted information and the results from exhaust

emissions test performed at Automotive Testing & Development

Services, the staff concludes that Jones Electronic‘s performance chips 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 be issued.

IV.     RFORMANCE   C    SCRIP

      Many computer controlled vehicles are equipped with an electronic

control unit (ECU) which is programmed using a prom.     Signals detected by

the vehicle‘s sensors are fed directly into the ECU where they are analyzed

and compared to the operational data programmed inside the prom.     The prom
                                     —1—


The results of the exhaust emissions test performed at Automotive Testing &

Development Services are shown in Table 1.

     The emissions test results at Automotive Testing & Development Services

indicate that exhaust emtissions of the vehicles with the Jones Electronic

Performance Chip installed are well below the emission standards for

that engine family.     This demonstrates that the installation of the Jones

Electronic Performance Chip on the applicable vehicles will not adversely

affect the exhaust emissions.

     Jones Electronic submitted alli the required information and fulfflled

the requirements for an exemption.


sends out appropriate adjustments in the engine operation in response to any

changing conditions.     For example, a prom will adjust timing and fuel

delivery when a vehicle is subjected to additional load.     Thus, by

modifying data in the prom, spark timing and fuel delivery can be adjusted.

     Jones Electronic Performance Chip modifies the ignition advances and

fuel curves of the original equipment manufacturer‘s (OEM) prom under full

throttle operation.    Therefore, the performance chip monitors and modifies

the vehicle operation under open—loop modes.     Jones Electronic claims these

modifications translate to an increase in torque and horsepower.        No

modifications have been conducted on the Performance Chip that would affect

throttle response and driveability, under closed—loop conditions (normal

day—to—day driving).     The manufacturer claims that modifications under

full—throttle operation offer enhanced performance and acceleration.         Jones

Electronic does not recommend the use of any particular fuel to obtain

optimum performance or avoid knocking which may be caused by advanced or

retarded timing.       Installation instructions, included with the chip, is

shown in Appendix B.

V.   DISCUSSION OF THE PERFORMANCE CHIP

     A 1991 Chevrolet C1500 full size truck with the 5.7 liter (350 CID) V—8

gasoline engine and TBI, was selected as the test vehicle to evaluate the

effect of the Performance Chip on tailpipe emissions.     This vehicle (5.7

liter Chevrolet C1500) was chosen because of its popularity to the consumer.

It is also subjected to more stringent emissions standard when compared to

the 454 CID GM trucks.     The test program consisted of one FTP CVS—75 (cold

start) test on the test vehicle in the modified configuration and evaluated

against the standards.
