92 vx lean burn
Honda vx 92-95 federal version. Runs on a 5 wire oxygen sensor. Car can run really lean. What would be the steps to gain more mpg? Car gets avg 45 mpg. 1.5 liter engine (d15z1) thank you. What would be the setting for it, as amp draws and production of HHO gas? Will it still required to manipulate car sensors?
