Bro if we had highways down here would have been a blessing. Hills and tons of corners. One main highway 4 lanes. 2 up 2 down. But all in all can't and won't trade the highways for the 365 sunshine and 80 degree weather..

 

Like I said - you should drive a scooter and enjoy the sunshine and the weather.

 

Don't throw it in the trash.

Open it up and see what's inside (besides resistors and wires).

If not, demand a refund for false advertising.

 

Yeah agreed but if they make a component that can save tons of money on fuel economy as well as increase power and sell it for $25?!? thats where you know its a rip off. A true ECU/Firmware chip's are out there and sell for hundreds of dollars, not $25

Either way i agree both are not worth buying. If there was something that could do that, im sure lexus would have it in the car stock

 

On an LS460 it is likely that premium gasoline will get better mileage than regular. The engine computer retards the timing to protect the engine if it senses pre-ignition. That reduces not only power but effeciency and thus fuel mileage. How much depends on the condition of the car (carbon build up in the head), how you drive (hard acceleration) and where you drive (mountains). The differences are likely small, but you do not get everything you paid for and the additional cost of premium is also small. On an engine set-up to burn regular, premium will not improve mileage.

Thanks, that's what I thought.

 

The Lexus ECU's are pretty much uncrackable at this point....
