Is this a hoax?

[S15RACER]

I have but one question, is this ebay add BS?

here it is.

Sounds like crap to me. The guy indicates that leaning out a mixture will decrease power. Which is not exactly true. Most aftermarket ECU's increase timing and lean out fuel curves to increase power. Of course you will need to use premium fuel.

it's all crap.

[S15RACER]

I figured it was to good to be true

It wouldn't surprise me if there was no circuitry in that box...

Why don't you e-mail the winner of the auction and ask if it really works?

[silviaNE]

good idea, still tinks its crap.

lean = faster...rich = same or slower...

I bought it just to see if it works and it added maybe 3-4 horsepower in the upper rpms but it did help gas mileage. I went up about 20 mpg. But it doesn't make how much it claims. If you want better gas mileage and a little gain buy it otherwhys screw it and get a jim wolf ecu thats what im saving up to do.

damn I wish my gas mileage would go up by about 20 mpg... be getting 35 mpg lol

[GELLIS2586]

I meant 20 miles to a tank sorry for the confusion i get an average of 26 miles to the galon right now.

i bought one a while back also and i was actually surprised. i could feel a small difference, kinda like when you have old plugs and wires and you replace them, the engine seemed to run better and rev quicker and the did get better gas milage, but i bought a jet chip which i like better. but for $35 i would say its worth it.
