that's exactly why I asked Sheddy if its a custom tune or just a ready file, am concerned that if it is pre modified parameters then we wont go anywhere with that except temporary fun till we get bored again
I already sent the deposit and tools are on the way, stage 2 should be in by next week
Baby steps Nuke lol.
A custom tune will require the tuner in your car making adjustments on the street or dyno, for now a tuned file will have to suffice. Keep us updated on the stage 2!
yeah i understand that replacing the turbo would prove a larger task but just changing out the turbine and compressor wheels can get the most out of the stock sized turbo. All they do is replace the internal components of the stock turbo and that lets it flow more air or spool faster depending on the set up you go with. something like this http://www.pureturbos.com/store/bmw-...1-upgrade.html
Im sure there are other companies or different examples of turbo upgrades, I am just familiar with this company
Also if this software allows for the tuner sitting in the car and lets him custom tune it, I know a top notch tuner in West Palm Beach. He uses a load based Mustang Dyno.

Yea i've heard of Pureturbos, if the market is there then maybe it can happen. There's a few tuning software companies being released so once that tuner knows the interface then it is possible.

Yea, it feels great! The adjustments TTI made on the boost, VVTI engagement, A/F etc. is very noticeable over stock.
What does TTI/Tony say about the supposed 30% throttle limitation Lexus uses below 3k rpm? Curious why this Tuner didn't find that or didn't address it? Lexus advertises 200T as making all availavle 258 lbs torque at below 2k rpm (I believe exact figure is 1650) so how does this car make FULL 258 ft lbs TORQUE at 30% throttle. Either Lexus lied in advertising or the tuner that found out this "30% throttle limitation below 3k rpm" doesn't know what he's talking about. Which is it? That's my curiosity!

I have emailed Tony about that earlier and he said that their tune removes the limitation completely..
Question: does the TTI reflash works fine in all modes (economic, normal, sport)? Or is it meant to work on a specific mode only?
Is the TTI flash only for stock and w/downpipe (stage 1/2) or can they tune it if you have more bolt on mods (intake, catback, downpipe, etc)?
How easy would it be to go back to stock (for warranty purposes) and then go back and do the reflash again? Meaning, do we have to buy again the reflash or not at all?
What's the expected gains for stage 2? Any official numbers yet? Will the TCU optimization add gains?
"TTI has been testing the throttle opening degree and pedal angle. Basically the stock throttle reaction is slower than the pedal which means that the pedal and the throttle do not move at the same time ,but we adjusted this parameter to synchronize the two. If you look at the dyno graph the green circle shows the before and after result which has been improved."

Yes, it works in all 3 modes. Eco you get the system to slower the throttle hence the "fuel savings" and in sport you get the more aggressive gearing with the stiffen steering wheel feel.

Stage 1 is perfectly fine for the stock setup and with modifications, but it is recommended to upgrade to stage 2 if you have bolt on's such as a down pipe to gain the full potential of the tune.

The writing of the tune is pretty simple, but the only issue would be the tools since you will need it to revert to stock. I am working with Tony to find out a simple solution for this matter. I think the dealer would not check your ECU for simple maintenance like an oil change and brake job but if something mechanical breaks then that would give them cause.

With the stage 2 tune + down pipe you are looking at an increase of 10-12 WHP than stage 1 + down pipe. The TCU upgrade will give the user faster shifts, leading to quicker acceleration.
dang it! i wish this came with a programmer. you could go from stock to stage 1 and back to stock in 10 minutes or less.
Yes, that would be awesome but right now only the IS250 and IS350 tune comes in the handheld device. The only 2 companies that offer a 200t tune (TTI and OV) use the same process of ECU writing tools.

then it looks like the burger piggyback for me then (i'd really love the tti though)...cuz i want to be able to retune at a moments notice.

Totally understandable, hopefully soon they can find a loop hole to make them programmable through the handheld device. It sure is a big difference between the reflash and piggyback but either way you will have more fun than stock!
Keep us updated on the stage 2!
