Has any one tried these? I see them on ebay for $5 and up.
It looks to just be a resistor, around 2600-2800 ohms plugged into one of the sensors.
Any thoughts?

 

I'd stay away from anything you plug into your vehicle on ebay. Get an Xcal tuner or something along those lines.

 

I also would be careful as to what I plugged into my truck. I follow the advice that if it is too good to be true, it usually is!

 

Dont get anything thats not Name brand off ebay! my friend burnt his ECU up by putting in a speed chip in his truck!

 

yeah i have a friend that does tuning for a living and he has checked many "ebay chips" programs to see whats on them.

in many occasions they state they are direct copies to popular name brand chips out there but are far from. many had discusting fuel amounts, weird air fuel amounts, you name it... everything wrong and in cases extremely bad for your motor.

stay away... unless its a brand you know stay away from it on ebay

 

All that thing is is a resistor for the IAT sensor that reports the wrong intake air temperature, which changes the mixture. Far from scientific. It will richen the mixture, which will give you a bit more power, but kill your gas mileage, possibly foul your plugs and cook your cats.

 

Yep.

Thanks guys, I won't be getting one of those.

 

I'd never buy anything for my truck off eBay. Full of scams and pranksters trying to make $$$ off crap.
