So here is my honest view on this device, when paired with the toms racing boost box, the car moves very smoothly and way better. When flooring it now the car doesn't hesitate anymore. My only gripe is when you are in stop and go traffic, just never have it on red as it is so touchy that you are mostly trying to control the peddle, as the slightest touch gives it a solid boost forward. Decided it was best to hide it in the coin box as it can never be seen by the dealership.

 

Great feedback. Probably my only complaint about the LS 500 is the throttle (or transmission) lag. Glad to know it can be addressed.
Can you post the part number of the controller and wire harness? The apexi site doesn't show the LS 500 as an option.

 

I post the exact one I got. I believe it is the same one for the GS and a couple other Lexus cars.

Thought I would provide an update to how its been working after using it for a couple weeks. So at first when I got it the pedal was very touchy, just the slightest tap would send it. Now it works perfectly, there is no touchy feel and it goes when I press the pedal now no delay still which I'm happy with. I guessing it learned or something because it definitely isn't as bad as it was when I first got it. Feels like it should have been out of factory.

 

Hello,

Yes it is the same application as most 2014+ Lexus models.

We have these pieces in stock!

Whats the install like? Plug and play?

 

Was pretty much plug and play for the guy that installed it for me. The hardest part was figuring where to put the button as I wanted it hidden from the dealership.

 

First thing I did with my LS. Installed the Apexi throttle controller from my GS and installed the Tom's Boost boost box. Love the change it brings out.
