Fitted, it gives you live ethanol content and fuel temperature, plus fuel pressure if you add a compatible sensor, and you can watch all of it on your phone through Nostrum's iOS app. Where a bare sensor only produces a signal, the module turns that signal into something a tuning platform or the factory ECU can actually work with.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eF-Series cars committing to flex fuel, where the blend changes with every fill and the map has to follow it.\u003c\/li\u003e\n\u003cli\u003eBuilds that need the ethanol reading fed to a tuning platform over CAN as well as watched on a phone.\u003c\/li\u003e\n\u003cli\u003eOwners starting from nothing who would rather buy one boxed kit than assemble a sensor, module and harness separately.\u003c\/li\u003e\n\u003cli\u003eCars where fuel temperature matters to the calibration, not just ethanol percentage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eReading Fuel At The Engine, Not The Tank\u003c\/h2\u003e\u003cp\u003eThe ESSIM takes its reading at the engine, which is what makes fuel temperature useful alongside ethanol content, and it publishes 0-5V analog, PWM and CAN outputs at the same time. Each output is configured individually and all three can run together, so a tuning platform, a dash and the factory ECU can all be fed without choosing between them. That flexibility is the practical difference between this and the \u003ca href=\"\/products\/nostrum-nostrum-bmw-f-series-ethanol-sensor-kit-l081-1109\"\u003eplain F-Series ethanol sensor kit\u003c\/a\u003e, which supplies the sensor and adapter lines but leaves the analyser to you.\u003c\/p\u003e\u003ch2\u003eKey Specs\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eManufacturer: Nostrum High Performance\u003c\/li\u003e\n\u003cli\u003eProduct Type: ethanol content module kit\u003c\/li\u003e\n\u003cli\u003eSKU: L187-1682\u003c\/li\u003e\n\u003cli\u003eVehicle Application: BMW F-Series\u003c\/li\u003e\n\u003cli\u003eMonitors: ethanol content, fuel temperature, and fuel pressure with a compatible sensor\u003c\/li\u003e\n\u003cli\u003eOutputs: 0-5V analog, PWM and CAN, configurable individually and usable together\u003c\/li\u003e\n\u003cli\u003eIncluded: ESSIM module, Continental ethanol sensor with bracket, vehicle-specific harness adapters, instructions\u003c\/li\u003e\n\u003cli\u003eExclusions: fuel pressure sensor is a separate purchase\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment And Setup Checks\u003c\/h2\u003e\u003cp\u003eNostrum publishes this as a BMW F-Series kit without breaking out the individual chassis codes and years, so send us your exact model, year and engine and we will confirm the harness adapters before you order. The app side is iOS only, so an Apple device is needed for phone monitoring. Decide up front which output the tune will use, and add a fuel pressure sensor if you want that channel as well.
