This service is intended for customers with modified engine combinations that require calibration support beyond a standard off-the-shelf reflash.\u003c\/p\u003e\n\u003cp\u003eMercury's 454\/502 engine packages from 1999-2000 are popular foundations for performance builds. Whether the setup includes a supercharger, camshaft change, cylinder head change, larger cubic inch combination, or other supported modifications, Whipple can develop a custom calibration to better match the engine's fuel, spark, and operating requirements.\u003c\/p\u003e\n\u003cp\u003eBecause each custom combination is different, calibration accuracy depends on complete setup details and proper customer testing. Custom calibration changes are based on customer-supplied engine information, ECM information, scan data, air\/fuel data, and operating feedback.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCustom Calibration Details\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCustom ECM calibration service for compatible Mercury Marine 454\/502 Mag applications\u003c\/li\u003e\n  \u003cli\u003eDesigned for supported MEFI-3 engine control modules\u003c\/li\u003e\n  \u003cli\u003eUseful for supported supercharged, cammed, headed, or larger-displacement combinations\u003c\/li\u003e\n  \u003cli\u003eCalibration is matched to the supplied engine and setup details\u003c\/li\u003e\n  \u003cli\u003eCustomer testing is required with proper scan tools or scan software\u003c\/li\u003e\n  \u003cli\u003eWideband air\/fuel monitoring is required to measure air\/fuel data\u003c\/li\u003e\n  \u003cli\u003eCustom calibration fee includes 1 year of calibration changes based on supplied test data\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eGM Part Number \/ MEFI Type Reference\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eGM Part #:\u003c\/strong\u003e 16237009\u003cbr\u003e\n    \u003cstrong\u003eMEFI Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eGM Part #:\u003c\/strong\u003e 16236999\u003cbr\u003e\n    \u003cstrong\u003eMEFI Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eEngine Control Module Identification\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eModel:\u003c\/strong\u003e MCM 454 Mag MPI\u003cbr\u003e\n    \u003cstrong\u003eSerial Number:\u003c\/strong\u003e 0L085400 and Above\u003cbr\u003e\n    \u003cstrong\u003eECM Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eModel:\u003c\/strong\u003e MIE 454 Mag MPI Horizon\u003cbr\u003e\n    \u003cstrong\u003eSerial Number:\u003c\/strong\u003e 0L086050 and Above\u003cbr\u003e\n    \u003cstrong\u003eECM Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eModel:\u003c\/strong\u003e MCM 502 Mag MPI\u003cbr\u003e\n    \u003cstrong\u003eSerial Number:\u003c\/strong\u003e 0L085433 and Above\u003cbr\u003e\n    \u003cstrong\u003eECM Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n  \u003cdiv\u003e\n    \u003cstrong\u003eModel:\u003c\/strong\u003e MCM 502 Mag MPI\u003cbr\u003e\n    \u003cstrong\u003eSerial Number:\u003c\/strong\u003e 0L086013 and Above\u003cbr\u003e\n    \u003cstrong\u003eECM Type:\u003c\/strong\u003e MEFI-3\n  \u003c\/div\u003e\n\u003c\/div\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eTesting And Calibration Requirements\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eCustom calibrations must be tested by the customer with proper equipment such as a scan tool or scan software and wideband air\/fuel meters to measure air\/fuel data.
