I'll make an install video when I get the chance, it's pretty straightforward. Because the O2 Sensor is a fluctuating voltage signal, it's baseline of .6 to .8 volts for a good 14.6 mixture can be offset in millivolts. The ECU will always attempt to maintain the same voltage, what makes an EFI-E System work is it's ability to keep a fluctuation pace with the actual O2 Sensor readings. While adding or reducing voltage to the O2 Sensor output before it reaches the ECU. Much like a millivolt step up-down. Though while you can make a waterproof case for it with a travel soap carrier. I'd still also recommend spraying both sides of the circuit board in liquid electrical tape to prevent condensation corrosion. Just be precise scraping the liquid electrical tape spray off only the adjustment screw and you should be good. Also, the adjustment screw is clutched. So you can step up or step down voltage without overturning the adjustment screw itself. I you get a Engine Code for the O2 Voltage being out of range, you've probably just mixed up the green and white wires. The EFI-E System requires a baseline voltage fluctuations to keep step pace with. So make sure you connect the O2 Senors output voltage to the EFI-E System's input wire so it can keep it's step pace with your O2 Sensor voltage. Otherwise it'll just be in the way and never detect baseline O2 Sensor Voltage and your bike will get no O2 Voltage through it causing your bike to go into limp mode and throw the "O2 Sensor Voltage Out of Range" Code. It's easy to switch them back if you do go into limp mode though. Just don't rush the green and white wires, make sure you soldier your 250 Ohm to the white wire and it's an easy install. I've got a link to the install as well as the 250 Ohm, which will give you 250 Ohms of enrichment or 125 Ohms of leaning. Just be sure you put it on the white wire so that you don't interfere with the EFI-E System's voltage fluctuation pacing. Anyways, here's the installation link and some 250 Ohms as well. ✌️
