Any One try this HP chip?

Hey i have seen this on ebay the passed year now and the guy is still selling them so i asoom that people must be buying them.
They are a so called HP performance chip for the WR250R/X. And from my knowledge all it does is tricks the FI and pushes more fuel.
But idk... So i was wondering if any of you guys bought one and tryed it out? And what your option was on it.

Here is the ebay link

I have never used one and never will. I believe that most of your replies will confirm that it is a total scam.

+25 hp?
Sure, maybe if the bike starts out with 500 hp. :)

The way I understand it, it simply fools the bike's electronics into thinking the outside air temperature is colder than it really is, richening the fueling a tiny bit.

I'd just put the money toward either an FMF Power Programmer or Power Commander.
I'd bet that either of those units would work a lot better than that E-bay unit.

If it's like the one for the CBR125R, it's an overpriced 5c resistor or 10c potentiometer/rheostat designed to do just that, alter the intake air temperature sensor's reading in order to richen the mixture. +1 for stay away...

Go with the Attitude. Best bang for the buck.

I could sell you one of these:

Yeah you guys pretty much conformed my option....Thanks

lol...if you look towards the bottom of that page they also can hook you up with some +10 HP sparkplugs too.

for the potentiometer....i remember reading on TT that MPfab (the turbo kit builder) also used a potentiometer(connected as a rheostat i'm sure...2 wires) when he was dyno testing his bike before the turbo install.....he was getting some good hp numbers too.

i'm not going along with this ebay seller on his product or any of his claims,but there are ways to "trick" or "modify" F.I. systems that do/can help.

Yes, indeedy.
Power Commanders and such units do just that.
The thing about this kind of ad is that is smeels too much like snake oil. :)

I have a wide power band in my shop I'm not using
I'd sell it for 50$

Throw in some blinker fluid, and you've got a deal. Ha!

Bowflex machine a little too much for ya?

I suppose you're the same guy that used to send the new starts for sky hooks, a bucket of oxygen, and left handed crescent wrenches...

I think that I still have that left footed soccer ball that someone gave me. I have not been able to use it correctly because I am right footed.

Now even I know a left handed crescent wrench is a rippoff, By the way, I have a full set of them for sale at half price
I also have 45 gallons of propwash for the boat owners out there

Hey, that's just what I need for my new power boat. I'd love to trade you even for 40 cubic feet of sailboat fuel that I don't need any more - I'll even throw in free airfreight.
