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—02—003;

IT IS ORDERED AND RESOLVED: That the instailation of the Elise/Exige ECU
Upgrade, manufactured and marketed by Lotus Sport (Potash Lane, Hethel, Norfolk,
NR14 8EZ, United Kingdom) 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 2005 through 2007 Lotus Elise
and 2006 Lotus Exige vehicles equipped with a naturally aspirated 1.8L engine.

The Elise/Exige ECU Upgrade features a modified calibration that lowers the RPM at
which the camshaft profile switchover occurs. No other changes are made to the OEM
calibration. The OEM ECU is removed from the vehicle and the Elise/Exige ECU
Upgrade takes its place.

This Executive Order is valid provided that the installation instructions for the
Elise/Exige ECU Upgrade 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 Elise/Exige ECU Upgrade,
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 Elise/Exige ECU Upgrade advertised,
offered for sale, sold with, or installed on a new motor vehicle prior to or concurrent with
transfer to an ultimate purchaser.

Marketing of the Elise/Exige ECU Upgrade using any identification other than that
shown in this Executive Order or marketing of the Elise/Exige ECU Upgrade for an
application other than those listed in this Executive Order shall be prohibited unless
prior approval is obtained from the Air Resources Board.


                                           19.


This Executive Order does not constitute any opinion as to the effect the use of the
Elise/Exige ECU Upgrade may have on any warranty either expressed or implied by the
vehicle manufacturer.

This Executive Orderis granted based on an engineering evaluation of the emissions
impact of the device if measured during the Cold—Start CVS—75 Federal Test Procedure
{(FTP) and the Supplemental FTP (SFTP) test cycles. It was determined that the device
will have no effect on emissions during the test cycles.

The Air Resources Board 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 THE ELISE/EXIGE
ECU UPGRADE.

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.

               LOTUS SPORT — ELISE/EXIGE ECU UPGRADE — D—616


                               EVALUATION SUMMARY


Manufacturer Name: Lotus Sport

Name of Device: Elise/Exige ECU Upgrade

Background: Lotus Sport of Potash Lane, Hethel, Norfolk, NR14 8EZ, United Kingdom
has applied for an exemption from the prohibitions of Section 27156 of the California
Vehicle Code for its Elise/Exige ECU Upgrade. The Elise/Exige ECU Upgrade is for
2005 through 2007 Lotus Elise and 2006 Lotus Exige vehicles equipped with a naturaily
aspirated 1.8L engine.

Recommendation: Grant exemption to Lotus Sport as requested and issue Executive
Order D—616.

Device Description: The Elise/Exige ECU Upgrade features a modified calibration which
lowers the camshaft profile switchover to 5750 RPM. The switchover in the OEM
calibration occurs at 6200 RPM. Lotus Sport claims that when using a Lotus Elise or
Exige vehicle on a race track, the OEM camshaift profile switchover point is slightly too
high. During cornering, the engine can change camshaft profile, causing the balance of
the car to be upset due to a step change in engine torque output. No other changes are
made to the OEM calibration. The OEM ECU is removed from the vehicle and the
Elise/Exige ECU Upgrade takes its place.

Discussion/Basis for the Recommendation: This Executive Orderis granted based on
an engineering evaluation. Lotus Sport provided data which shows that during the
Cold—Start CVS—75 Federal Test Procedure (FTP) and the Supplemental FTP (SFTP)
test cycles, the Elise/Exige engine never exceeds 5000 RPM. Since the revised
camshaift profile switchover occurs at 5750 RPM, the device will have no effect on
emissions during these test cycles.
