                                 EXECUTIVE ORDER D—175—19
                          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 authdrity 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 Diesel Controller marketed by
Hypermax Engineering, Inc., 255 E. Route 72, Gilberts, Illinois 60136 has been found not to
reduce the effectiveness of the applicable vehicle pollution control system and, therefore, is
exempt from the prohibitions of Section 27156 of the Vehicle Code for 1993 through 2001
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.‘s Diesel Controller >
advertised, offered for sale, sold with, or installed on a motor vehicle prior to or concurrent with
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.


HYPERMAX ENGINEERING, INC.                             EXECUTIVE ORDER D—175—19
DIESEL CONTROLLER                                      (Page 2 of 3)



This Executive Order is granted based on submitted emissions test data, conducted at Roush
Industries, on a 2000 Ford Excursion with a 7.3L diesel engine. Testing consisted of
comparative Cold Start 505 Federal Test Procedures.

                  HC        CO     NOX      PARTICULATES
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 show the 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), oxides of nitrogen (NOx) and
Particulates, and 15 percent or 1.0 grams per mile carbon monoxide (CO) 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 (OBD I1) testing and opacity
testing on the same test vehicle. Opacity test results are listed below. Test data showed that
the Diesel Controller when installed on the vehicles did not significantly affect the vehicle‘s
smoke opacity or the ability to perform its OBD II 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.‘s 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 supercharger 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 such test results or
other evidence provides the ARB with reason to suspect that the supercharger 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.

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 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.

ACCREDITATION,; APPROVAL, OR ANYOTHER 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 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 feceipt of the request
