Lexus is350 ECU tuning. Finally possible??
Ah, JET... the company that once (allegedly) charged someone to "reflash" their ECU then sent the ECU back untouched other than adding a "JET" sticker to the side... good stuff
review highlights-
You'll get one or more of the following out of your purchase:
1) No benefit whatsover besides being able to read OBD2 output (which you could've done cheaper)
2) A tiny initial bump in power (if it does the IAT trick like many of the rip-off "chips" do) which goes away within 50-100 miles as the stock ECU tunes the error back out
3) A Check engine light (least likely, but least desirable) if it lies too badly to the ECU about something
Mostly what you'll have done is waste your money by not having asked here first before buying it.
If you want something that'll actually make real, doesn't vanish quickly, tuning possible, you'd need to buy one of the few piggyback systems proven to work like the MAPECU3 or HKS F-con Pro... (though they're nowhere near worth the cost for the small 5-10 hp gains you'd receive on an NA car)
review highlights-
This product offers just a visual representation of the vehicles "performance". It in NO WAY modifies, alters, improves or increases performance
followed the instructions on this to the tee, after about a dozen tanks of gas and gas receipts with mileage written on them, I've noticed no difference to if I was driving without this. Wish I could return it for a full refund

After a bit of searching, I just came across the Jet V-Force Plus Power Control Module. Just pulled the trigger on it. I need to go get a dyno baseline, and then another one after I install this piggy back. Engine wise, all i have on it is a M2 catback exhaust and the F-Sport intake. If I get it early this week, Ill be going to the dyno later this week.
Now all you need now is a super ZX5000 turbo intake on that puppy and you're GOLDEN! Make SURE to get the before and after on this badboy. I heard it's like 12.5hp.
Also.. I hope you didn't pay more than $18.85 for that V-Force module. My boy in TX is getting 45 extra HP with this rocket pod! WOOT!

this sounds about right...my cousin has a 350 tuned from this guy that did it at his house. he has no onboard additions and he DRAGS my 430 and many other cars on the road. 18-20hp sounds about right. everyone on this post seems so closed minded.
Nobody here is closed minded. We know what the limitations of our cars are. So many people THINK they can tune these cars and make threads claiming they can and we never hear from them again. Realize that this isn't possible, if it was you would here it from our forums first, not a company claiming they can do it
Are these systems typically attempted by car tuners or computer experts? It seems all computer to me. Maybe the right computer hacker hasn't come along. Or maybe that person is hired by Toyota

It would be awesome if someone could crack it. Especially since no one makes a stand alone unit for cars with direct injection, the driver board I guess is too expensive or something. But more DI engines are showing up at wreckers and there is a growing demand for new stand alone units that can run direct injectors. Plus all those people with factory DI turbos systems. The best we can hope is a really good piggy back system
There's a pretty good line of argument that anyone who admitted to breaking this, or offered a tool that did so, would be violating the DMCA and get a visit from some lawyers (or worse).
Hence why you don't see anything but piggyback systems (or insanely expensive standalone choices)
so i guess all those intake companies that claim you gain 15hp are extremely open minded

While this thread seems to have died, I am curious as to what ever happened. Did the OP (or anyone else) follow up with Eurocharged and send in the ECU?
I realize I may be new here and that a lot of this has been gone over many times before but there seems to be a lot of nay sayers here. With that defeatist attitude no wonder nothing gets done.
I am no stranger to the "impossible" as I worked in the Dodge Chrysler world and professionally tuned the late model HEMI vehicles for a few years. Diablosport was able to crack the older PCM's eventually and even the newer stuff with the ANN (revolving code). While the initially released templates weren't always the greatest, they generally kept after it when the demand was there to get the necessary tables visible and working. Now, I think there are 2 other companies besides Diablosport that have unlocked the PCM and a few others (Eurocharged included) now offering TCM support. All of this was "impossible" a few years ago.
The point I'm making is that given the resources, knowledge base and time I bet it would be possible.

Something like this gives the ability to read/write. The hardest part is trying to decipher what you've read and put it in usable templates and tables. This is where the biggest disconnect seems to be: what the computer guy see's and what the tuner needs to see.
Also, as an aside, I think piggy backs could be more effective that you guys make them out to be. Of course the ECU will adjust back the part throttle CL fuel changes. It was a defined AFR it's shooting for and will adjust accordingly. I'd be surprised if WOT fueling was CL though and I'd think those changes would stick. But, if you want CL part throttle fuel tuning look at something like the FIC8. Not to control the injectors or MAF voltages at part throttle but to offset the O2 sensor voltage. Your typical wideband is 0-5v 10:1-20:1 AFR. If you wanted a global change you could almost get away with a voltage dropping circuit: i.e. if you wanted to run leaner, drop the output voltage of the O2's making the ECU think it's richer than it is and it will pull fuel making the resulting mixture leaner.
Seriously, you guys should stop saying "impossible". Instead say "difficult".
One last thing: no one probably tried (or continues to try at least) to unlock the Supra ECU because you can buy a standalone for cheaper than the hardware needed to pull the data. That's pure dollars and cents...

Look, I was just trying to throw it out there to not be so pessimistic. This is not a very large community in terms of the car world. It was my hope that as these cars become more affordable and people buy them (my case) and want to mod them, there may be an increasing demand for a solution.
Instead, you guys keep harping on garbage snake oil "chips." I thought from what I wrote that I would get more constructive, educated responses.
Great attitudes... no wonder no one wants to even attempt at working on this.
