I want to get some cheap horsepower from my LS460 and I've always had good luck with ECU reprogrammers for my other vehicles. Does one exist for the LS 460? If so, what brand? And if I do flash the ECU will it trigger a Check Engine light?

nothing at all. toyota ecu is known for being hard to crack. up till this point i have yet to really see a lexus ecu being hacked., given that more mod demanding cars like IS and GS don't even have hacked ecu, i doubt you'd see any for ls460l

No one has an ECU reprogram for any Lexus or Toyota. If you hear someone making claims about tuning the ECU...RUN! But in all seriousness, Toyota programming has never been decoded, even by the top well-known Japanese tuners out there.

Your best bet is to source out small mods like a reusable intake drop in filter or an aftermarket exhaust. Engine/performance mods for the LS are very very very limited and almost non existent unfortunately.

Thanks for the reply. how the heck does Toyota think they are going to compete with Subaru, Mitsubishi, Infinity, etc in Tuners espcially in an IS without this. I guess I need to reserve my go fast ambitions to my other vehicles. So i guess I will turn on my heated seat and steering wheel, relax with my ML sound and chill. Toyota has given me no choice

Air intake no problem - yea I'll do it. exahust maybe.

for sure lexus doesn't even care about mitsubishi and subaru, it's not really in the same class. i will agree on infiniti, mods for the g35 seems to be more than that of 2is

What about transplanting a Euro Lexus ECU (150 mph) into the NA model?

Or are there impediments in place to prevent that?
