For those of you who are interested in the price of both of these units it's on Ben's web site (
http://www.aj-racing.com/).
Wave, after reading the description at AJR I think that one unit is just a voltage stabilizer and the other is just an ignition booster. In addition, both units cost the same amount.
Ben can you please confirm that the ignition booster doesn't have the voltage stabilizer built into it too or vice a versa?
