whereas, purscant to the authority vested in the undarsigned by California
Health and Safety Code Section 39516, the Mr Resources Board (ARB) finds:
           1. the Miero—controiler feedback control. systen is a device
              desiqned to replace the original oxidation catalytic
              converter with a closed—loop three—uay catalytic converter.
              The vehicle‘s fusl mixture is nonitored and maintained clome
              to stoichfomatzie by leaning the fuel mixture when rich. The
              system consiste of a XAZ 200 computer manofactured by
              weutzonics, an oxygen senwor (P/N AFSITP for heated 02 and
              #/M 25105901 for unteated 02) manofactured by ho belco, a
              lineae actuated stepper notor valve (P/N ©92120) manfactured
              by Mr Packs, & wiring harnees and a theoe—way aftermacket
              catalytic convertes, with provistons for air for those
              vehtcles with ale infootion, (P/N 22100 and 29200 nee
              attachnent A for converter application) manifactured by Car
              sound.
           2. The Micro—controtles feedback control systen satistios the
              test requirements and meats the standards estabiished for
              acoreditation by achloving at least a 20 percent reduction in
              enissions of bydeocarbonand oxides of nitzogen with no
              Inceesse in carbon nosowide. This finding is based on
              exhaust enteeton data derived from six test venicles.
           3. the exhaost ensnion reductions discuased Sn the staff report
              rafiect the levels typical for the model, ago and mileage of
              the test vehicles. NoTE A eanple of six vehicles may not
              be adequate to repressnt the entaston reductions that could
              be achieved if the Micro—controlier feadback control. system
              is installed on a fleet of vehicles

           4. the appiicant subnitted durability data for Lts Moro—
              controiler feedback control. system. Durability‘and entston
              performance of the system at 20,000 mtlea were based on
              durability test data of a 1979 Cheveolet B1 Canino equipped
              with a 5.01 engine, a 1979 Volkswagen Seizocco equipped with a
              1.6t angine and a 1975 Dateun 2710 equipped with a 2.0L
              angine.
           5. The ARS in the exercise of technioal. dudgement consludes that
              the Mero—controller feedback control system will not cause
              substantial entssion reductions on lean=burn vehicles.
im 18 onorrzp anp mesotVED: that Mestronicrs Enterprisas, Inc.‘s Mioro—
controiler feedback control. system, consisting of a KP 200 conputer, a Car
Sound aftermazket catalytic converter, an oxygen sensor, a wiring hazness
and an air valve, is herepy sccredited as an entesfon—control device sold on
« non—nandatory basis pursuant to section 43630 of the fealth and Safety
Code, the Micro—controller feedback control system shall be applicable for
gascline vehicien equigped with an opan—loop oxidation cataiytlo converter
systen. Thix accreditation is mubjact to the following conditions
           1. the following information shall be provided with the saie of
              each devices Instructions for maintaining the Mloro—
              controiler feedback control. system in proper working
              condition. Because no vehicle in the appiication class is
              coreantly covered by an enasion control system wassanty
              required to be provided by the vehicle nanifacture, the
              requirenent to provide notice that instailation of the device
              may invalidate the ventcle enisaion control. systen warvanty is
              waved.
           2. This secreditation does not authorize the alteration or
              nodification of emiusion control devices required by law or
              regulstion, except what has been specified by the installation
              instructions. No changes to the tuning epecificatione is
              pernitted other than what the manufactures has specified in

                for any parpone. Use of the davice for enteston credite will
               require testing of a larger vehicle sanple size to deternine
               the entesion redustions representative of the vehicle fleet.
