Instead of assuming what came out of the forecourt pump, the calibration gets a live reading of ethanol content and fuel temperature taken at the engine rather than back at the tank, so the map responds to the fuel actually reaching the rail. The module puts out analog, frequency and CAN signals that can all be used at the same time, so it feeds a tuning platform such as HP Tuners while you watch the same numbers on the Bluetooth app. It arrives as a vehicle-specific kit, pre-terminated, with the sensor already mounted on its stainless bracket.\u003c\/p\u003e\u003ch2\u003eWhy Reading Fuel At The Engine Matters\u003c\/h2\u003e\u003cp\u003eEthanol content varies between filling stations, between seasons and between tanks, and every splash of petrol on top of an E85 fill moves it again. A map written for one blend is running blind on another. Sensing at the engine also catches the real fuel temperature, which is a genuine variable on a hot-running turbo V6 in traffic. Once the ECU can see both, the tuner can build a proper flex strategy rather than a conservative fixed map, and you can fill up wherever you happen to be.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eExplorer ST and Lincoln Aviator owners running E85 or moving between blends\u003c\/li\u003e\n\u003cli\u003eCars already fitted with an upgraded pump and injectors that now need a flex strategy\u003c\/li\u003e\n\u003cli\u003eAnyone who wants to see ethanol content on a phone before committing to a hard pull\u003c\/li\u003e\n\u003cli\u003eBuilds calibrated in a platform that can take an analog, frequency or CAN ethanol input\u003c\/li\u003e\n\u003cli\u003eDrivers who fill at different stations and cannot rely on one consistent ethanol blend\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: ethanol content sensing module kit\u003c\/li\u003e\n\u003cli\u003eSKU: L087-1378\u003c\/li\u003e\n\u003cli\u003eVehicle Application: Ford Explorer ST and Lincoln Aviator, 3.0L EcoBoost\u003c\/li\u003e\n\u003cli\u003eFitment type: vehicle-specific\u003c\/li\u003e\n\u003cli\u003eMeasures: ethanol content and fuel temperature, sensed at the engine\u003c\/li\u003e\n\u003cli\u003eOutputs: analog, frequency and CAN, usable simultaneously\u003c\/li\u003e\n\u003cli\u003eApp: Bluetooth monitoring on iOS\u003c\/li\u003e\n\u003cli\u003eIncluded: pre-terminated ESSIM unit, Continental ethanol sensor on a stainless bracket, vehicle-specific low pressure fuel lines, pre-terminated harness adapters, hardware, instructions\u003c\/li\u003e\n\u003cli\u003eNot included: ECU calibration, fuel pressure sensor\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe module supplies the signal; your calibrator still has to build the flex strategy that uses it.
