The voltage adder is DONE! One note: In the video, I did mis-speak regarding using this unit with a wideband O2 sensor. This unit will NOT work with a wideband sensor because it's designed to add VOLTAGE. To work with a wideband sensor, we would need to bring in the O2 voltage and add RESISTANCE to drop voltage (since wideband sensors use lower voltage to signal rich) before sending the altered voltage to the ECM. Therefore, the ECM sees O2 sensor voltage from our unit ONLY and never sees it directly from the sensor itself. Such a unit would not need to be powered because it would be, essentially, a variable resistor inline between the sensor and the ECM. I caught that after I made this video. This video shows the box with the enhancements. I added an external battery holder you simply plug into the side of the voltage adder box to make it easy to remove if you need to change batteries. Note that the original battery I've been using has been in use every day and still shows about 1.6 volts as it did when it was new, so there has been no real degradation of its capacity. I also added a "battery test" LED to the 'down' position of the switch to make it easy to see that your battery pack is connected and you are getting volts to the unit. There is a 1k resistor connected to the LED to prevent it from being quickly burned out by the battery pack. I may build a separate unit for wideband sensors but have no plans to do so right now.http://www.freewebs.com/jhines2/index.htm
