What's the benefit of them doing all the R&D to crack a NA V6 ECU, if the 2IS came boosted from the factory then yes. What parameters would they change if they did crack it? A stock ECU for boosted applications has numerous options to up boost increase fuel etc. I'm aware that there are several Euro NA cars that have had their ecu flashed etc.. but it seems those ecus are easier to work on and the demand is there. The 2IS doesn't get much respect in the tuning world.

Kurtz you gotta remember most of the guys here grew up in the fast&furious days, they know nothing of what high compression ratios means, all they know is bolt on a turbo and GO~

*for you ECU want-to-be-hacked guys*
It took HKS EIGHT YEARS to crack the ecu for the rx-8 to make a turbo kit for it, the isX50 isn't a a sports car so dont expect anyone to be trying to crack the toyota encryption~ much less with a 12:1 compression ratio, as Kurtz said~ just what kind of return are you expecting? It would be more cost effective to drop in a chevy sb...

*edit* before someone goes talking about flat spots in the rpm range and stuff like that, please~ taking care of a flat spot is NOT gonna take a second off your 0-60 or 1/4mi times...

Exactly, I was just stating facts and the obvious. If for whatever reason the 2IS was turbo or supercharged from the factory it would have been a different situation.

Nobody sells one in the US market anymore.

LMS did for a while, but since almost nobody on earth wanted to pay $6000 for 40 hp they only sold like 3 of them and gave up on it.

One member has ordered the HKS kit from Japan (pricing seems to be in the $6000-ish range as well, depending on exchange rate and shipping) and after some modification and making his own wiring harness he was able to get it to work on the US IS350, including the HKS f-con tuning portion (it's not really tuning in the sense that you can't easily change the tune yourself, but it's an active piggyback system when plugged into the OBD2 port at least). Ideally, if it continues to work well, it's likely to produce better than 40 hp (possibly more in the 60-80 hp range) due to running higher boost... though AFAIK there's not much information on how well the motor stands up to anything above 6 psi long term.

after five years of answering these question on the 2IS you would think youd know the stock IS350 numbers

I haven't been answering these questions for 5 years lol, never even drove or rode in a IS350. Don't really care about stock numbers, I don't even know or care what the stock numbers are on my TL ha ha.

How much time are you thinking exactly?

More likely this will simply never happen.

On the GT-R I'm guessing you mean the speed limiter crack that COBB came up with? COBB was looking at the Lexus/Toyota ECU stuff at least 3 years ago (I know HKS350 spoke to them about it in mid-late 2008 and they were working on it at the time) and after all that time has produced no results for these cars (and I would suspect have since given up). World Tuning was working on it even longer back and nothing.

Seriously, don't hold your breath.

(though I keep wondering what exactly people are expecting to happen if someone did manage it... the car still has ~12:1 compression so it's not like you can slap a huge turbo on and run 20 psi if you just crack the ECU)
