Use this app with a bluetooth module to get ethanol content and fuel temperature streamed right to your smartphone! bluetooth modules support ethanol content and fuel temperature data streaming as well as built in sensor error detection and analog 0-5v output for ECU datalogging. These modules can be used to supply a converted ethanol content signal to the vehicle’s ECU for flex fuel support and datalogging or can be used to monitor ethanol levels in cars tuned on specific ethanol blends. has many options available ranging from basic low-cost solutions to full plug-and-play systems for popular tuner platforms such as Subaru and Mitsubishi.

Our modules convert the standard frequency based output from a GM ethanol content sensor to an ECU friendly 0-5v analog output. Fuel temperature and error mode detection are also utilized to get the most out of the available information and provide a rich feature set at half the cost of other ethanol content modules on the market.

Analog output values for modules are 0.5v = 0%Ethanol and 4.5v = 100%Ethanol. Output will drop to 0v upon detection of a sensor error to alert the ECU that a problem has occurred. modules also include a calibration mode that will allow the analog output to be precisely calibrated to the vehicle for the utmost accuracy.
