PPE Engineering IS350 header development
I don't think the DMCA applies to this specifically - Cobb cracked the Nissan GT-R ECU (big hooplah about how nissan made it un-crackable to cut down on aftermarket modifications that were so prevalent in previous skylines). The GT-R and IS are apples oranges, obviously, as you stated. But Cobb also offers products for the Infiniti G35/37 and 350/370Z. I think these would be fairly similar in terms of gains. Again, it's not just about re-writing the ECU on a stock car, but maximizing EACH car with the mods it has.
How much are they getting out of those products for just intake and exhaust on an NA car though?
Edit- I went and checked. On the G37 for example their Stage 1 NA tune adds 3% hp and 2% torque.
Whoa. Better get a crash helmet! They're sure unleashing the power with that tune!

DMCA does apply. Whether the manufacturer wants to pursue it is the real question. Cracking other ECMs has been fairly trivial. I know someone with inside knowledge of this industry and a lot of hands on experience cracking encrypted embedded systems. He owns a Scion tC with turbo and has spent (off and on) the last three years trying to decrypt the software to directly tune his 4AZ-FE without needing somebody's piggyback or an aftermarket ECM. He's still running an eManage, and it's his business.
I've known people since 1995 who have worked to crack the Supra ECM, and even the best at G-Force (now Technosquare) using TechTOM from Tom's Racing don't know fully what is going on with Toyota's engine management.
So, tuning the ECM in the ISx50 isn't likely to happen any time soon unless we can find a disgruntled Toyota engineer willing to supply the magic codes necessary to crack the ECM. It's really unfortunate for those of us who love Toyotas. All the other brands have someone (or someones) who will part with this information. Toyota apparently does not.

Hey guys, I'm sorry to say this but I do not have an update yet. We went to do the dyno today and the computer system at the shop kept crashing right as we went to start the pulls. We are re-scheduled for Monday so unfortunately we will have to wait until then to see the results. Again, I'm sorry about this, I am also frustrated by it, but there is nothing we can do until they fix their computer issue.
Make sure that the dyno operator knows that he has to use ECT Snow mode limitted to 4th gear. This will allow him to go full throttle at 2500 RPMs in 4th without it automatically downshifting to 3rd. Snow mode does NOT reduce power at all, so please make sure they do this.

last shop i went to did not do this and i had to reschedule.
Also take note of their dyno procedure for both sessions to make sure they don't deliberately skew the numbers. Their's an easy 10 RWHP difference just by leaving the hood down for one run, then up for the second.
Oh ... and take a 3.5" disk or flash drive with you so you can get copies of their dyno data files. That way you can make your own graphs with the display options you want.
