                           EXECUTIVE ORDER D—175—20

                    Relating?to Exemptions Under Section 27156
                           '     Of the Vehicle Code

                               Hypermax Engineering, Inc.
                                   Diesel 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 S ORDERED AND RESOLVED; That the installation of the Diesel Controlier
marketed by Hypermax Engineering, Inc., 255 E. Route 72, Gilberts, IIlinois
60136 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 1993 through 2002 model year trucks
equipped with a turbocharged Navistar 7.3L diesel engine.

The Diesel Controller is a replacement ECM that has been reprogrammed to
increase fuel delivery at wide—open—throttle (WOT).

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

This Executive Order shall not apply to any Hypermax Engineering, Inc. Diesel
Controller advertised, offered for sale, sold with, or installed on a motorvehicle
prior to or concurrent with the transfer to an ultimate purchaser.

Changes made to the design or operating conditions of the Diesel 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.

Marketing of the Diesel Controller using any identification other than that shown
in this Executive Order or marketing of the system 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 the system shall not be
construed as exemption to sell, offer for sale, or advertise any component of the
kit as an individual device.


                                           3.


This Executive Order is granted based on submitted emissions test data,
conducted at Roush Industries, on a 2000 model year Ford Excursion equipped
with a Navistar 7.3L diesel engine. Testing consisted of comparative Cold Start
505 Federal Test Procedures. The following test results, in grams per mile, are
listed below.              £

                      HC     CO      NOx    PM
‘Stock               0.59    2.5    5.5    0.23
Diesel Controller     0.56   2.7    5.7     0.18
% Difference         —5.0    8.0    3.6    —21.7

Results from the emission tests showed that vehicle emissions with the Diesel
Controller installed did not cause exhaust emissions to exceed the baseline
emissions by more than the allowed limits of 10 percent or 0.1 grams per mile on
Hydrocarbon (HC) and Oxides of Nitrogen (NOx), 15 percent or 1.0 grams per
mile Carbon Monoxide (CO) and 15 percent or 0.03 grams per mile particulate
matter (PM), as specified in the "Procedures for Exemption of Add—On and
Modified Parts".

This Executive Order is also based on the On—Board Diagnostic II (OBDII) testing
and opacity testing conducted on the same test vehicle. Opacity test results are
listed below. Test data showed that the Diese! Controller when installed on the
vehicles did not significantly affect the vehicle‘s smoke opacity or the ability to
perform its OBDI} monitoring.

                     Opacity (percent)
Stock                4.9, §5.7, 4.3
Diesel Controller     5.0, 6.1, 4.5

However, the ARB finds that reasonable grounds exist to believe that use of the
Hypermax Engineering, Inc. Diesel Controller 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 Diesel Controller adversely affects emissions during
off—cycle conditions (defined as those conditions which are beyond the
parameters of the Cold Start 505 Federal Test Procedures), this Executive Order
shall be effectively rescinded as of the date the test results are validated.
Further, if suchtest results or other evidence provides the ARB with reason to
suspect that the Diesel Controller will affect the durability of the emission control
systems, Hypermax Engineering, 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.

                                        «3.


In addition to the foregoing, the ARB reservesthe 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 any opinion as to the effect the use of
the Diesel Controller may have on any warranty either expressed or implied by
the vehicle manufacturer.

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 HYPERMAX ENGINEERING, INC.‘S DIESEL CONTROLLER.

No claim of any kind, such as "Approved by the Alr Resources Board", may be
made with respect to the action taken herein in any advertising of 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.

Executive Order D—175—19, dated January 2001, is superseded and of no further
force and effect.
