The engine ECU will no longer be accessible through BMW diagnostic software. Engine diagnostics and fault management are performed through Syvecs SCal software.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eTraction control operation:\u003c\/strong\u003e The Syvecs traction control system offers improved performance over the factory strategy. The OEM ESP button can be assigned within SCal using AN20, allowing traction control settings to be adjusted or disabled.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFuel consumption gauge with larger injectors:\u003c\/strong\u003e The fuel consumption calculation can be adjusted under SCal, Fuel Consumption, Injector Consumption Scaling. A suitable starting point is injector size divided by 60.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eSwitching between calibrations and maps:\u003c\/strong\u003e The recommended solution is a Syvecs Calibration Rotary Switch, available through Syvecs or an authorized dealer. It provides instant access to multiple maps, traction settings, boost levels, and launch control configurations.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFueling and ignition for turbocharged applications:\u003c\/strong\u003e The supplied base calibration uses the naturally aspirated Alpha-N strategy. For forced-induction applications, a MAP sensor can be connected to a spare ECU input. Additional fueling can be configured under Run Mode, Fueling, Corrections, Simple Manifold Pressure Multiplier. Ignition timing can be adjusted under Run Mode, Ignition, Corrections, Simple Manifold Pressure Adder.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eWideband lambda sensor support:\u003c\/strong\u003e The kit supports dual LSU4.9 wideband lambda sensors as standard and can also be built with an option for dual NTK sensors.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eAdditional parts:\u003c\/strong\u003e Turbocharged or supercharged applications require an external MAP sensor wired into the plug-in adapter.\u003c\/p\u003e \u003ch3\u003eOrder Today:\u003c\/h3\u003e \u003cp\u003eAn authorized Syvecs dealer can discuss requirements and arrange an order.\u003c\/p\u003e","brand":"SYVECS","offers":[{"title":"Default Title","offer_id":43130110116020,"sku":"S7Plus-BE46","price":4992.17,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0628\/2605\/3812\/files\/image-coming-soon_d0ea64c4-72ed-4458-a7b0-4cec21d97c63.png?v=1789644832","url":"https:\/\/atomic-shop.eu\/products\/syvecs-s7plus-be46-engine-ecu-s7plus-kit-for-bmw-m3-e46","provider":"ATOMIC-SHOP Performance Parts \u0026 Motorsport Equipment - EU","version":"1.0","type":"link"}
