Tuning an engine for maximum power previously required long trial-and-error sessions on a dynamometer. With the Innovate, precise AFR measurement allows the user to correctly adjust many variables- including carburetor jetting, fuel injection, turbo fuel curves, etc.- without long and expensive dyno sessions. The meter's digital signal processing technology provides data on exactly how rich or lean an engine is running at any load. The Innovate's self-calibrating circuitry also compensates for changes in temperature, altitude, and sensor condition.
The instrument can sample and store the air-fuel-ratio and the other sensor data internally in operation for later analysis on a personal computer. At a sampling rate of 12 samples/second the instrument can store up to 44 minutes worth of data in non-volatile memory. The data can be downloaded to a personal computer using a standard serial port and viewed/analyzed by the included software or any standard spreadsheet program:
The standard Innovate includes a Bosch wide-band oxygen sensor and cable, cigarette-lighter adapter, serial cable for PC connection, 9V battery, exhaust bung and plug, CD and manual. The Innovate ships with a Bosch sensor, however, it can also function with other wide-band sensors, including Honda/NTK and VW sensors.
Available accessories include auxiliary input cables, alligator-clip power cable, exhaust clamp, analog output cable, and Aux. input expander. Additional accessories include a dash-mountable display and AC adapter.
The Innovate sells for $349, including the oxygen sensor (Bosch LSU4.2), 10' sensor cable, 10' power cable, serial PC cable, and software.
The Technology
Innovate has developed a breakthrough technology for measuring the oxygen concentration of a gas. This invention is most directly applicable to improving the measurement of the air/fuel ratio of the exhaust of any combustion engine, allowing for major improvements in performance, efficiency, and emissions.
Features:
Significantly more accurate than analog/conventional method
A fraction of the cost of analog/conventional
Self-calibrating and self-compensating for pressure and temperature variations
Benefits:
Precisely and quickly tune any engine, at any temperature, altitude, or condition
Achieve maximum power, maximum efficiency, or minimum emissions under any conditions
Enable “closed loop” ECU operations in which fuel injection is controlled relative to constant, accurate measurement of lambda (vs. pre-stored maps that relate intake air mass to fuel mass without feedback)
No calibration resistor required in the sensor itself, thereby simplifying production and lowing cost
Wide tolerances of sensor are acceptable, therefore increasing yield and lowering cost
