Hallo HHO gurus,
Can somebody tell me whichone of these EFIE-s is the most efficient. If possible I want to get one where I dont have to play with the potmeter, because I want to Install a system allso to some of my friends car and I want to make it as safe as possibe. When there is no potmeter, they cant damage, the engine by running it to lean. I have read the topic of the FS2, and want to lookaround, for another solution.
I attached a picture of each device, one of them is with potmeters. All of them are from ebay.
