                            EXECUTIVE ORDER D~234—1
                   Relating to Exemptions Under Sectionr 27156
                              of the Vehicle Code

                         JONES ELECTRONIC TECHNOLOGIES
                            J.E.T. 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;

IT IS ORDERED AND RESOLVED:  That the installation          of the J.E.T. Performance
Chip manufactured by Jones Electronic Technologies          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 1986—92 General Motors    (GM)   trucks with 5.0 to 7.4 liter
engines, 1981—92 GM passenger cars with 2.8 to 5.7 liter engines and 1986—92
GM trucks with 2.8 to 4.3 liter engines as listed in Exhibit A, which is
attached hereto and incorporated herein.

This Executive Order is valid provided that installation instructions for
the J.E.T. 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 o#her 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 J.E.T. 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 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 J.E.T. 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


JONES ELECTRONIC TECHNOLOGIES                           EXECUTIVE ORDER D—234—1
                                                        (Page 2 of 2)




other evidence provides the ARB with reason to suspect that the J.E.T.
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 TECHNOLOGIES‘ J.E.T. 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 untrue or
misleading advertising unlawful, and Section 17534 makes violation
punishable as a misdemeanor.

Section 43644 of the Health afid 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.

Executive Order D—234 is superseded and of no further force and effect.

                                   SUMMARY

     Jones Electronic Technologies (JET) of 7602 Talbert Avenue, Huntington

Beach, CA 92648, has requested to update Executive Order D—234, which

exempts JET‘s J.E.T. Performance Chip from the prohibitions of Vehicle Code

Section 27156 of the California Vehicle Code.    The existing Executive Order

D—234 exempts JBT‘s J.E.T. Performance Chip for installation on 1991 and

older model—year General Motors (GM) trucks with 5.0 to 7.4 liter engines.

The update is requested to include 1992 model year GM trucks with 5.0 to 7.4

liter engines.   JET has also requested that 1981—92 GM 2.8 to 5.7 liter

passenger cars and 1986—92 CM 2.8 to 4.3 liter trucks be included in the

exemption.

     Based on emission test results performed on a 1989 4.3 liter Chevrolet

Blazer and a previously tested 1991 5.7 liter Chevrolet full size truck, and

that the 1992 vehicles for which the exemption update is requested are

carry—overs from the model—years for which an exemption has been granted,

the staff concludes that JET‘s J.E.T. Performance Chip will not adversely

affect exhaust emissions on the specified vehicles when tested in accordance

with Cold Start CVS—75 Federal Test Procedure.

     The staff recommends that JET be granted Executive Order D—234—1

allowing the installation of their J.E.T. Performance Chip on applicable

1986—92 CM trucks with 5.0 to 7.4 liter engines,   1981—92 GM passenger cars

with 2.8 to 5.7 liter engines and 1986—92 GM trucks with 2.8 to 4.3 liter

engines as listed in Appendix A.

          SECTION 27156 IN ACCORDANCE WITH SECTION 2222, TITLE 13, OF
                       THE CALIFORNIA CODE OF REGULATIONS

I.     INTRODUCTION

       Jones Electronic Technologies (JET) of 7602 Talbert Avenue, Huntington

Beach, CA 92648, has requested to update Executive Order D—234, which

exempts JET‘s J.E.T. Performance Chip from the prohibitions of Vehicle Code

Section 27156 of the California Vehicle Code.     The existing Executive Order

D—234 exempts JET‘s J.R.T. Performance Chip for installation on 1991 and

older model—year General Motors (GM) trucks with 5.0 to 7.4 liter engines.

The update is requested to include 1992 model year GM trucks with 5.0 to 7.4

liter engines.      JET also requested that 1981—92 CM 2.8 to 5.7 liter

passenger cars and 1986—92 CM 2.8 to 4.3 liter trucks be included in the

exemption.

       JET claims no changes to the installation instructions or tune—up

specifications are necessary for use of the J.E.T. Performance Chip on the

1992 updates.

II.    CONCLUSION

       Based on emission test results performed on a 1989 4.3 liter Chevrolet

Blazer and a previously tested 1991 5.7 liter Chevrolet full size truck, and

that the 1992 vehicles for which the exemption update is requested are

carry—overs from the model—years for which an exemption has been granted,

the staff concludes that JET‘s J.E.T. Performance Chip will not adversely

affect exhaust emissions on the specified vehicles when tested in accordance

with Cold Start CVS—75 Federal Test Procedure (FTP).


III. RECOMMENDATION

      The staff recommends that JET be granted Executive Order D—234—1

allowing the installation of their J.E.T. Performance Chip on applicable

1986—92 GM trucks with 5.0 to 7.4 liter engines,    1981—92 GM passenger cars

with 2.8 to 5.7 liter engines and 1986—92 GM trucks with 2.8 to 4.3 liter

engines as listed in Appendix A.

IV.   DESCRIPTION OF J.R.T.   PERFORMANCE CHIP

      Many computer controlled vehicles are equipped with an electronic

control unit (ECU) which is programmed using a programmable read only memory

computer Chips (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 sends out appropriate

adjustments in the engine‘s operation in response to 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.

      JET‘s J.E.T. Performance Chip modify the ignition timing and fuel

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

throttle operation.   Therefore, the performance Chips monitors and modifies

the vehicle‘s operation under open—loop modes.     JET claims these

modifications translate to an increase in torque and horsepower.      No

modifications have been conducted on the J.E.T. Performance Chip that would

affect throttle response and driveability under normal day—to—day driving.

The manufacturer claims that modifications under full—throttle operation

offer enhanced performance and acceleration.     JET does not recommend the use

of any particular fuel to obtain optimum performance or avoid knocking which

                                       —2—


may be caused by advanced or retarded timing.       Installation instructions,

included with the Chips, is shown in Appendix B.

v.   DISCUSSION OF THE J.E.T.   PERFORMANCE CHIP

     JET has requested an update to Executive Order D—234 to allow the use

of their J.E.T. Performance Chip on the applicable 1992 model—year vehicles.

The J.E.T. Performance Chip for 1992 model year vehicles modifies the engine

parameters in a similar manner to those previously approved for the 1991 and

older model—year vehicles.    The staff compared the engine design of the 1991

and 1992 model—year vehicles.     Since the majority of the 1992 model—year

General Motors engine families certified for California sales were carried—

over from the 1991 model—year, no additional exhaust emission tests were

required or performed.

     To evaluate the emissions impact of the J.E.T. Performance Chip on

1981—92 GM passenger cars with 2.8 to 5.7 liter engines and 1986—92 GM

trucks with 2.8 to 4.3 liter engines, the staff required JET to perform

CVs—75 emission testing on the J.E.T. Performance Chip using a 1989

Chevrolet 4.3 liter Blazer.     The test program consisted of one CVS—75 FTP on

the test vehicle in the modified configuration evaluated against the

standards for that vehicle.     The results of the exhaust emissions test

performed at Automotive Testing & Development Services are shown in Table 1.

Difference                    ~0.223       —3.074    —0.419


     Staff also reviewed emission data on a previously tested 1991 5.7 liter

V—8 C1500 truck.   Based on the emission data from the 1989 4.3 liter V—6

Blazer and the 1991 5.7 liter V—8 C1500 truck,   the staff concludes no

emissions impact would be observed on the affected vehicles when tested in

accordance with Cold Start CVS~75 Federal Test Procedure (FTP).

     The staff recommends that JET be granted Executive Order D—234—1

allowing the installation of the J.E.T. Performance Chip on 1986—92 GM

trucks with 5.0 to 7.4 liter engines,   1981—92 GM passenger cars with 2.8 to

5.7 liter engines and 1986—92 GM trucks with 2.8 to 4.3 liter engines.

     JET submitted all the required information and fulfilled the

requirements for an exemption.
