¶ Project Outline
A/F Ratio Tuning/Visualization Device Development Project Summary
¶ Objective
To facilitate setting and visualization of the air-fuel ratio of a motorcycle.
By visualization, we would like to understand the health condition of motorcycles and evaluate the appropriateness for customization of intake and exhaust systems.

¶ Background
Custom ECU chips, sensor spoofing, and other devices of questionable effectiveness have been sold in large numbers.
However, users do not have the means to objectively evaluate the validity of these devices.
¶ Target.
- Motorcycle users with one or two Bosch narrowband O2 sensors
- BMW R1100S, R1150R, R1150RT, and R1150GS are targeted until STEP 1 described below.
Because the basic specifications of the air-fuel ratio measurement and ECU are the same as those of the test machine (R1100S).
¶ GOAL
Develop and market a device that can set and visualize closed-loop and open-loop A/F ratios using a smartphone.
¶ Development Steps
¶ STEP1
- Develop a device that utilizes a stock narrow band O2 sensor
- Operation via smartphone
- Open-loop map switching function by coding plug (optional)
¶ STEP2
Development of device using commercially available Bosch broadband 02 sensor
->In short, a smartphone version of LC-2
->Function for Speeduino Wideband O2 Sensor controller.
¶ STEP3 (undecided)
Development of a device with sub-controller function
->In essence, upward compatible with PowerCommander3.
->Smartphone operation, visualization of air-fuel ratio, and log acquisition
