                             EXECUTIVE ORDER D—176—5
                    Relating to Exemptions Under Section 27156
                               of the Vehicle Code

                          DINAN PERFORMANCE ENGINEERING
                                PERFORMANCE CHIPS

 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 Performance Chips
 manufactured by Dinan Performance Engineering has been found not to reduce
 the effectiveness of required motor vehicle pollution control devices and,
 therefore, are exempt from the prOhlblthflS of Section 27156 of the Vehicle
 Code for those applications listed in Exhibit A, which is attached hereto
 and incorporated herein.

 This Executive Order is valid provided that installation instructions for
 the Performance Chips 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 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 Performance Chips 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 Performance Chips
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.  Further, if such test

                                                       (Page 2 of 2)



results or other evidence provides the ARB with reason to suspect that the
Performance Chips will affect the durability of the emission control system,
Dinan Performance Engineering 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 DINAN PERFORMANCE ENGINEERING‘S PERFORMANCE CHIPS.

                                   SUMMARY




       Dinan Performance Engineering (Dinan) of 81 Pioneer Way, Mountain View,

CA 94041, has requested to update Executive Order D—176—2 which exempts Dinan‘s

Performance Chips from the prohibitions in Séction 27156 of the California

Vehicle Code (VC).   The update is requested to include 1992 & 1993 M—5 models,

and 1992 325i, 535i, and 735i models.   Dinan also réquested the exemption to

include PROM chips for the following vehicles models:    325e, 3251i, 525e, 525i,

528e, 750iL, and 850i.   Appendix A lists the model—year and engine displacement

of both the update and the additions.

       Based on an engineering evaluaéion and that the 1992 and 1993 vehicles

for which the exemption update is requested are carry—overs from the model—

years for which the exemption has been granted, the staff concludes that

Dinan‘s Performance Chips will not adversely affect exhaust emissions from the

vehicles for which an exemption is requested.

       The staff recommends that Dinan be granted Executive Order D—176~—5

allowing the installation of their Performance Chips on those applicable BMW

                    EVALUATION OF DINAN PERFORMANCE ENGINEERING‘S
              PERFORMANCE CHIPS 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

         Dinan Performance Engineering (Dinan).of 81 Pionéer Way, Mountain View,

CA 94041, has requested to update Executive Order D—176—2 which exempts Dinan‘s

Performance Chips from the prohibitions in Section 27156 of the California

Vehicle Code (VC)}.      The update is requested to include 1992 & 1993 M—5 models,

and 1992 325i, 535i,; and 735i models.      Dinan also fequested the exemption to

include PROM chips for the following vehicles models:        325e, 325i, 525e, 525i,

528e,   750iL,   and 850i.   Appendix A li;ts the model—year and engine displacement

of both the update and the additions.

II.      CONCLUSTONS

         Based on an engineering evaluation and that the 1992 and 1993 vehicles

fér which the exemption update is requested are carry—ovérs from the model~—

years for which the exemption has been granted, the staff concludes that

Dinan‘s Performance Chips will not adversely affect exhaust emissions from the

vehicles for which an exemption is requested.

III.     RECOMMENDATION                 ‘

         The staff recommends that Dinan be granted Executive Order D—176—5

allowing the installation of their Perforfiance Chips on those applicable BMW

vehicles listed in Appendix A.

Iv.      DESCRIPTION OF THE PERFORMANCE CHIPS

         Many computer controlled vehicles are equipped with an electronic

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

computer chip (PROM)}.       Signals detected by the vehicle‘s sensors are fed

                                            —1—




                                                              snn w sb ns un ran n w w coum


directly into the ECU where they are analyzed ané compared to the operational

data programmed inside the PRdM.      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, ;park timing, fuel delivery, and

rev—limiter can be adjusted.

        Dinan‘s Performance Chips modify the ignition timing, fuel curves, and

rev—limiter of the original equipment manufacturer‘s (OEM) PROM under full

throttle operation.     Therefore, the Performance Chips operate when the vehicle

is at open—loop.     These modifications translate to an increase in torque and

horsepower.     No modifications have be;n conducted on the Performance Chips that

would affect throttle response and driveability under normal day—to—day

driving.     Dinan recommends that premium fuel be used in conjunction with their

Performance Chips.

v.      DISCUSSION OF THE PERFORMANCE CHIPS

        Dinan has requested an update to Executive Order D—176—2 to allow the

use of their Performance Chips on the applicable 1992 & 1993 model—year

vehicles.    The Performance Chips for 1992 & 1993 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,    1992, & 1993 model—year vehicles'and found that the 1992 & 1993

model—year BMW engine familieé certified for California sales were carried—over

from the 1991 model—year.    Therefore,    no additional exhaust emission test is

necessary.

        Dinan also requested to include new PROM chips for the following

vehicles models:     325e, 3251, 525e, 525i, 528e, 750iL and 850i.    The engine

                                           —2«—


sizes for these vehicles are within the range of sizes previously evaluated

under the original ayplication.   The modified parameters of the new PROM chips

are the same as those which are already exempt.   Based on previous emission

testing and the information submitted regarding the new PROM chips, the staff

concludes no emissions impact would be observéd on the affected vehicles when

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

       The staff recommends that Dinan be granted Executive Order D—176—5

allowing the installation of the Performance Chips on those applicable vehicles

listed in Appendix A.

       Dinan submitted all the required information and fulfilled the

requirements for an exemption.
