                              EXECUTIVE ORDER D—186—24
                       Relating to Exemptions Under Section 27156
                        '           of the Vehicle Code

                           ELECTRONIC VALVE 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 Electronic Valve
Controller, EVC IV & EVC EZ, produced and marketed by HKS USA, Inc., 2801 E. 208""
Street, Carson, California 90810—1102, 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
vehicles equipped with OEM turbochargers and certified to Tier—1 or Tier—0 standards
(not TLEV, LEV, or ULEV}.                 *

The Electronic Vaive Controller (EVC IV & EVC EZ) modifies the boost levels of
turbocharged vehicles by interrupting the actuator signal to the turbocharger wastegate,
thereby, increasing boost to the engine. The Electronic Valve Controller measures
boost and vacuum as part of the criteriafor the level of elevated boost selected by the

This Executive Order is valid provided that the installation instructions for the Electronic
Valve 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 Electronic Valve Controller,
as exempt by the Air Resources Board, 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 Electronic Valve Controller advertised,
offered for sale, sold with, or installed on, a motor vehicle prior to or concurrent with
transfer to an ultimate purchaser.

ELECTRONIC VALVE CONTROLLER                                  (Page 2 of 3)

Marketing of the Electronic Valve Controller using any identification other than that
shown in this Executive Order or marketing of the Electronic Vaive 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 not constitute any opinion as to the effect the use of the
Electronic Valve Controller may have on any warranty either expressed or implied by
the vehicle manufacturer.                 |

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 f1) system. A 1999 model—year Mitsubishi Eclipse
with a 2.0 liter fuel injected engine (XDSXVO2.0GBP, Tier—1, PC) was used for the
evaluation of the Electronic Valve Controller. Results from emissions testing conducted
at California Environmental Engineering are shown below (in grams per mile):

                       50k         NMHC        CO          NOx
                 Emission Level    0.203      2.270        0.241
                 (w. DF applied)
                       STD         0.25       3.4          0.4

                      100k ©    NMHC           CO          NOx
                 Emission Level 0.220         2.482        0.262
                _(w. DF applied)
                       STD         0.31       4.2          n/a

The emission test results in the modified configuration were below the applicable
emission standards with the deterioration factors applied. Examination of the OBD II
system showed the Electronic Valive Controllerdoes not affect OBD 11 operation.
Therefore, based on the test results, the staff concludes that the Electronic Vaive
Controller meets the criteria for exempting general criteria parts. However, the ARB
finds that reasonable grounds exist to believe that use of the Electronic Valve 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 Electronic Valve 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

ELECTRONIC VALVE CONTROLLER                                (Page 3 of 3)

such test results or other evidence provides the ARB with reason to suspect that the
Electronic Valve Controller will affect the durability of the emission control system, HKS
USA, Inc., 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

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 after
hearing that grounds for revocation exist.
Executed at El Monte, California, this          day of December 2000.

                                 R. B. Summerfield, Chief
