I use Ebay for a lot of purchases, if a seller is making bogus claims, they can be reported-only numbers matter to ebay, if they received enough complaints stating that these claims were impossible, they would probably act-
fact is, I think that anyone who buys this crap deserves to be 'taken', and it just proves that most people know nothing about cars-this guy is selling a 30 cent transistor from radio shack that keeps the ecm in open loop-eventually, the idiot buyer is going to have more problems from the engine running out of range while warmed up, being told that it is cold. like magnets for the fuel line, or 'hydrogen' fuel cell kits, electric turbochargers, proof that there is a sucker born every minute.
