Possible ECU Remapping for IS250/350?

So how exactly does this "auto tune" work?
Is it basically tricking the computer into thinking the weather is cooler, air is denser ect?
So the ECU will switch over to a more aggressive map, advance the timing, run a little bit leaner ect.
Kinda like a more sophisticated version of those so called "ebay chips" that you use to fool the ECU?

I spoke to vivid. They basically said I could return the unit and get a full refund prior to 30 days. I'm with the guys above. How long does the tune hold. I can't find any reviews for lexus online. A lot in vw and Porsche and it seems to be legit. But turbo vs na comes to mind. I built a g37s and never got 20 whp numbers from the mods. Another 10plus would be good but thI'd statest 20hp and 40tq. I'm not completely sold

If not then I wonder why they were loaded in the ECU in the first place when they're never used.
I'm a bit skeptical that somehow VR stumbled upon a way to enable these super maps...
I really hope it's true though, I would love to buy it for my IS-F if it really did work.

This should give you some answers- http://www.vividracing.com/catalog/v...150794665.html
I would so buy it if it works on the IS-F, right now we are getting conflicting information on whether it's compatible or not..

I've noticed simply resetting the ECU by disconnecting the battery seems to make the car more responsive. Could this be whats causing the change in dyno results instead of the chip? I mean maybe car's ECU had learned to drive somewhat slow, they tested it, then applied flash reset ECU, he drove hard for a week, and presto great dyno results

I am a bit skeptical about this maybe the throttle response and faster shifting but I don’t see this making all that power. Hopefully someone can explain this better and we can get a real independent test.
So, it only works with automatic transmissions?
