I found "speed guru's racing" mod chip on ebay.
Here is the link...

I don't know how it can possibly make the engine that much stronger...

 

it's just a resistor chip don't bother.

 

Lighter Wallet = Faster Acceleration

 

theres a proper tune and map industry for a reason and to see 75 bhp out a cooper youd need nos / rotex / turbo

 

Sorry, I didn't get it quite well. So, that's just a chip and I need to buy something else right?

 

I think the chip is just a bluff to make your wallet lighter. You'd have to spend lots of money, thousands of dollars to be precise, to see such an increase of power on a MC, if ever.

 

This is what it equates to. All you will recieve is a resistor that you can pay 25 cents for at Radio Shack. They will then tell you to unplug the IAT sensor and bend the resistor into a U shape and place either end into the two electrical sockets on the removed IAT sensor. You will then wrap this up with tape to hold it in place and if you are lucky, they will even send you a "zip tie" to hold the dangling sensor away from moving parts. They will feed you the bogus line that by jumping the connections, you are tricking the computer into thinking that the car is running colder. In other words, Please do not waste your money.

 

what there selling on ebay is best described as a scam to get any power out of a cooper your looking at a couple of thousand in new head, manifold and then a rotex supercharger or turbo and that would entail new pistons and to handle it all a 6 speed gertag box of the cooper s

all in about 10K USD min

 

Actually, that's the one part of the claim that's *not* bogus. The resistor in the IAT circuit tricks the car into thinking it's not warmed up yet, so the ECU enrichens the air/fuel mixure, just like it does during normal startup/warmup.

The richer mixture might net you a few horsepower (less than 10 hp) in very specific circumstances, but it's going to come at the expense of overall drivability and fuel economy.

But yes - it is a scam. Even if the device is enclosed in a nice sealed box filled with epoxy, it's just a resistor. Some of the companies will claim that there's a computer chip in the device, or will even go so far as to use a DIP-packaged resistor network (which looks like an old-style computer chip to anyone that doesn't know better).

 

Thank you very much everyone
