This service is intended for customers with custom engine combinations that require calibration support beyond a standard off-the-shelf upgrade.\u003c\/p\u003e\n\u003cp\u003eCustom calibrations may be used for supported Mercury Racing engines with modifications such as camshaft changes, supercharger upgrades, exhaust\/header changes, fuel system changes, or other performance-related updates. Because each custom engine combination is different, the calibration must be matched to the complete engine, boat, fuel, hardware, exhaust, and operating setup.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCustom Calibration Requirements\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCustom calibration service for compatible Mercury Racing engines\u003c\/li\u003e\n  \u003cli\u003eDesigned for supported custom engine combinations and performance modifications\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\u003eCalibration changes are based on customer-supplied setup details, scan data, and air\/fuel data\u003c\/li\u003e\n  \u003cli\u003eCustom calibration fee includes 1 year of calibration changes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eWideband And Testing Notes\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eA wideband oxygen sensor must be installed in a collector or common area that represents the average of a bank. Never use a wideband sensor in just one cylinder for calibration work. A single-cylinder wideband location may be useful for troubleshooting or individual-cylinder testing, but it is not suitable for normal calibration development.\u003c\/p\u003e\n\u003cp\u003eFor stainless-style marine exhaust systems, the preferred wideband location is typically in the tailpipe within 2\"-3\" of the header flange. For cast-style exhaust, testing may require a spacer between the manifold and riser, or an 18mm oxygen sensor bung welded into a compatible stainless tubular riser.\u003c\/p\u003e\n\u003cp\u003eWhipple does not tune marine engines using dry automotive dyno headers because those headers can produce different results than the wet marine exhaust system used in the boat. If an engine is dyno tested, it should use the same marine wet-style headers or exhaust configuration it will run in the boat for proper calibration accuracy.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cu\u003eCalibration Service Process\u003c\/u\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe PCM or ECM must be removed and sent to Whipple Superchargers for calibration service. Include a copy of the receipt and all relevant engine, boat, fuel, exhaust, supercharger, injector, sensor, scan data, air\/fuel data, and setup details with the computer. Typical turnaround time is 7-10 days.\u003c\/p\u003e\n\u003cp\u003eNew PCM or ECM units may be available upon request. Custom calibration worksheets and test notes should be completed as thoroughly as possible so Whipple has the information needed to build and revise the calibration for the application.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplication note:\u003c\/strong\u003e Verify engine model, PCM\/ECM type, fuel octane, engine modifications, exhaust configuration, wideband location, testing equipment, and complete setup details before ordering.
