HHO Installation Frequently Asked Questions

I get asked the same questions over and over so I decided to make a video to answer some of them. Here are the different questions I will answer. 1. How much HHO do I need to put in my engine 2. What is an EFIE and a Map/Maf Sensor Controller? 3. What is a PWM? 4. Does the VOLO chip work? 5. What kind of mileage gains can I expect? HHO Forum Links:
