Bernardo Cout, San biego, California 92127 has agplied for scceeditation of its Miero— controller feedback control system, pursuant to sestion 43630 and section 2010, mitre 13, com + 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

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 the inataliation instructions. 3. No changes are pernitted to the systom ss described in the staff report.
