for sale in the United States (or by Environment Canada for sale in Canada) and shall be available to the
general public for purchase. Additions and deletions of automobiles shall be at the discretion of the SCCA®.
The vehicle identification number (VIN) shall correspond with the model automobile classified. At least
one VIN plate or stamping shall remain in place on the dashboard or chassis that corresponds with the
model automobile classified.
D. CLASSIFICATION

b. The OEM source code, logic, or executable for the software or firmware build shall not be modified in any way.
c. Adjustment to vehicle performance parameters (such as drive mode, throttle map, maximum motor output power, maximum
regenerative braking level, etc.) is permitted only if the OEM software or firmware allows for the adjustment through the
vehicle’s OEM user interface (touchscreen, electromechanical selector, push button, etc.). Adjustment to vehicle performance
parameters through external test equipment, third-party devices, or through the OBD2 port is prohibited.

SCCA ELECTRIC TOURING (ET) RULES DRAFT
SCCA ELECTRIC TOURING – 120122a
CAN bus, to the stand-alone data acquisition system is permitted. The stand-alone acquisition system must be “read-only” and must
not modify any parameter on the databus in any way. Any data-acquisition sensor added to the vehicle is prohibited from
interfacing with the vehicle’s software/firmware and the data acquisition system must not tie into the vehicle electronics in any
other manner beyond this allowance.
g. An official SCCA data acquisition device may be required during practice, qualification, or a race. The data acquisition device may
require an electrical interface with the vehicle and may be used for compliance purposes (e.g. software and firmware versions,
allowable adjustments to performance parameters, etc.). It is the responsibility of the competitor to
SCCA ELECTRIC TOURING (ET) RULES DRAFT
SCCA ELECTRIC TOURING – 120122a
provide any adapter cable(s) required to electrically interface between the vehicle’s data acquisition
output and the official SCCA data acquisition device. Specifications on any official SCCA data
acquisition device, including electrical interfaces, will be provided in the event’s supplemental
regulations.

eccentric bolts (crash bolts) at the strut-to-spindle, slotted strut mounting holes at the spindle, and/or by use of any slotted camber
only adjuster plate at the top of the strut mounting plate. If upper strut slotted plates are used, they shall be located on existing
chassis structure, utilizing the manufacturer’s original bolt holes and may not serve as reinforcement for that structure.
Modifications to the top of the strut tower may be made to allow for camber adjustment only. On other forms of suspension,

fourth inch (1/4”) mesh may be added in front of the radiator and contained within the bodywork. The rake angle of radiator(s) is
unrestricted.
c. Dry ice, (a.k.a. solid carbon dioxide), may be used to cool the cooling loop radiators except for when the vehicle is in false grid, in pit
lane, in impound, in motion, or inside any building (including garages). Dry-ice must be in a mesh basket or perforated container
