What if you were to replace a small amount of the gasoline or with a another fuel (or simply add a small percent) that has an extremely fast burn rate, to help ignite more of the fuel in the camber faster. Has anyone on here ever done any conclusive testing of HHO? I have been reluctant to bring it up, since there are some pretty strong opinions on whether it does truly improve efficiency. I am hoping to someday have the time to datalog and analyze the true effects, and then possibly tune the fuel and spark curves to take advantage of the mixture.
