You've probably seen the performance chips on EBAY. I have an 02 F4i. Would getting one of these even be worth my time(Will I notice a difference). any of you had experience with them.

Example:

nope won't work

a fuel injected motorcycle works on a closed loop fuel system. ie, the variables that it accounts for when injecting fuel into the motor are RPM, and throttle position. On a car it also accounts for o2 sensor readings as well as a MAF/MAP sensor. In essence if you fuel a car's computer by altering one of those signals (o2 or MAF/MAP) you can adjust the fuel curve on your car. With a bike the only way to adjust the fuel curve, is to actually adjust the fuel curve (PCIII)

oh and IAT is your air intake temp sensor, some motorcycles might use this to richen or lean the mixture slightly based on ambient tempurature. So by fooling this system, you might be able to introduce a slight increase in fuel, but probably not enough to make a huge difference.

If these are anything like the "performance chips" that they sell on ebay for cars, it's a scam. All it is is a resistor that attaches to your IAT sensor. You could buy the resistor at radio shack for like a buck, and do it yourself if you wanted, but I wouldn't recommend it. They compare their product to performance programmers and chips, but they're not even close. I call scam.
