                                EXECUTIVE ORDER D—517
                        Relating to Exemptions Under Section 27156
                                     of the Vehicle Code

                                 1.8T BOOST CONTROLLER

 Pursuant to the authority vested in the Air Resources Board by Section 27156 of the
 Vehicle Code; and

 Pursuant to the authority vested in the undersigned by Section 39515 and Section
 39516 of the Health and Safety Code and Executive Order G—45—9;

 IT IS ORDERED AND RESOLVED: That the installation of the 1.87 Boost Controller,
 produced and marketed by Split Second, 2824 S. Willis Street, Santa Ana, California
 92705, has been found not to reduce the effectiveness of the applicable vehicle
 pollution control systems and, therefore, is exempt from the prohibitions of Section
 27156 of the Vehicle Code for 2000 and older model—year Volkswagen/Audi vehicles
 equipped with OEM turbocharged 1.8 liter engines, excluding the Audi TT coupe and

 The 1.87T Boost Controller modifies the boost levels (user selectable) of the applicable
 vehicles by interrupting the actuator signal to the turbocharger wastegate, thereby
 increasing boost to the engine.

—This Executive Order is valid provided that the installation instructions for the 1.8T Boost
 Controller will not recommend tuning the vehicle to specifications different from those of
 the vehicle manufacturer.

 Changes made to the design or operating conditions of the 1.8T Boost Controller, as
 exempt by the Air ResourcesBoard, which adversely affect the performance of the
 vehicle‘s pollution control system shall invalidate this Executive Order.

 This Executive Order shall not apply to any 1.8T Boost Controller advertised, offered for
 sale, sold with, or installed on, a motor vehicle prior to or concurrent with transfer to an
 ultimate purchaser.

1.8T BOOST CONTROLLER                                     (Page 2 of 3)

Marketing of the 1.8T Boost Controller using any identification other than that shown in >
this Executive Order or marketing of the 1.8T Boost Controller for an application other
than those listed in this Executive Order shall be prohibited unless prior approval is
obtained from the Air Resources Board.

This Executive Order does notconstitute any opinion as to the effect the use of the 1.817T
Boost Controller may have on any warranty either expressed or implied by the vehicle

This Executive Order is granted based on emission test results in the modified
configuration using the Cold—Start CVS—75 Federal Test Procedure and an examination
of the On—Board Diagnostic II (OBD II) system. A 2000 Volkswagen Passat with a 1.8
liter turbocharged engine (YADXVO1.8332, LEV, PC) was used for the evaluation of the
1.87T Boost Controller. Results from emissions testing conducted at California
Environmental Engineering are shown befow (in grams per mile):

                       50k      NMOG          CO        NOx       HCHO
                 Emission Leve! 0.051        0.565     0122      0.0006
                 {(w. DF applied)
                       STD          0.075    3.4       0.2        0.015

                      100k      NMHC          CO        NOx       HCHO
                 Emission Level 0.073        0.886      0.191    0.0016
                 {w. DF applied)
                       STD          0.090    4.2        0.3       0.018

The emission test results in the modified configuration were well below the applicable
certification standards with the deterioration factors applied. Examination of the OBD II
system showed the 1.8T Boost Controller does not affect OBD II operation. Therefore,
based on the test results, the staff concludes that the 1.8T Boost Controller meets the
criteria for exempting general criteria parts. However, the ARB finds that reasonable
grounds exist to believe that use of the 1.8T Boost Controller may adversely affect
emissions of motor vehicles when operating under conditions outside the parameters of
the CVS—75 Federal Test Procedure. 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 1.8T Boost Controller 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 other evidence provides the ARB with reason to suspect that the 1.87 Boost
Controller will affect the durability of the emission control system, Split Second, 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.

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.                             .

Violation of any of the above conditions shall be grounds for revocation of this order.
The order may be revoked only after a ten—day written notice of intention to revoke the
order, in which period the holder of the order may request in writing a hearing to contest
the proposed revocation. If a hearing is requested, it shall be held within ten days of
receipt of the request and the order may not be revoked until a determination is made
after the hearing that grounds for revocation exist.
Executed at El Monte, California, this   2 4 day of March 2001.
