200T - D3 Performance Tune
Thanks for the quick responses to the both of you!
Lexus3GIST, you mentioned that in the first post "Does not have to be plugged in while driving." so how exactly does this thing work?
I checked on their site and it's missing some info (to me at least):
When they say Cold Air Intake, are they referring to a specific one?
Enhanced throttle response is in normal mode too or the car has to be in sport mode?
The gains are same regardless of which tune is selected, based off what's on their site, so is an intake even necessary?
Also, do you have any videos? off the line or a rolling start run?

I checked on their site and it's missing some info (to me at least):
- High Octane Performance Tune: +25-31 horsepower and +32-37 lb-ft of torque.
- High Octane Cold Air Intake Performance Tune with enhanced throttle response : +25-31 horsepower and +32-37 lb-ft of torque.
- High Octane Performance Tune with increased engine speed limiter (6400 RPM) and sport shift points: +25-31 horsepower and +32-37 lb-ft of torque.
- High Octane Cold Air Intake Performance Tune with enhanced sport throttle response, increased engine speed limiter(6400 RPM) and sport shift points : +25-31 horsepower and +32-37 lb-ft of torque.

- Correct. You plug it into your car through the OBD port under the steering wheel and it will ask you to back-up your stock ECU calibration onto the device for safety. Once your stock ECU settings are saved, it will allow you to load any of the 4 tunes onto your car. Once you've completed the instructions on the screen (and gone for a little fun drive) you can unplug the device and keep it somewhere safe in case if you ever want to flash back to your OEM ECU Calibration. The backup and reflash process takes probably less than 5-10 minutes. You can also leave it plugged in if you want a little performance gauge/monitor, but I like keeping my dash clean.
*Regarding the 4 different tunes and how they all have the same HP input/The gains are same regardless of which tune is selected, based off what's on their site, so is an intake even necessary?
- It's possible that each tune has a different torque curve but has the same peak whp/torque output...or the gains between all of the maps between 25whp to 31whp. I won't speculate further than that since I'm not a representative of them. If you want to shoot D3 an email, they're super responsive and should be able to get back with you with a definite answer.
*High Octane meaning 94? (in Quebec we have 91 and 94 only)
- Here in Texas (same state as D3) our high octane gas is 93. Any questions, feel free to ask D3 via email.
*When they say Cold Air Intake, are they referring to a specific one?
- I can say with 90% certainty, no.
* Enhanced throttle response is in normal mode too or the car has to be in sport mode?
- The throttle response in Eco, Normal, and Sport are all refined with the D3 (if I recall correctly). D3's Normal mode is better than the stock Sport mode, and D3's Sport mode is much more responsive than the stock one.
As for videos, yeah I've got one but I could not get good traction on my 0-60 because my tires were trashed. I'll see if I can find and upload for you.

When it comes down to it, D3 Performance tune is a plug and play unit that uploads a new flash or ecu map to your ecu. You can remove the unit after you complete the flash or you can keep it plugged into your OBD2 port to do some logs or to change your maps.
It enhances the over all performance in every drive mode. If the car is stock, it will be improved. If you have aftermarket modifications like a downpipe, intake, exhaust, etc, the improvements from the D3 performance tune over stock are greatly enhanced.
The 8AR-FTS was severely under tuned from the factory. D3 helps unlock the potential on all levels in a quick and simple process. I would recommend this as the first mod to anyone.
Figured I'd update the thread since I spoke with D3 earlier for the first time since dropping my car off. Boy am I freakin' excited to see the progress on this car in the future.
12/21/2022 - My car is still with D3 as they continue R&D for the 8AR-FTS. I reached out to D3 today to see how things were going: No updates yet. Even though the engine is capable of putting out ~400HP (with supporting modifications), it will take time, patience, and a lot of hard work from D3 to get there. As the holidays approach, I'm thinking things will probably move a tad slower. Just wanted to touch base with an update as I went silent for a bit here. I'll do my best to let them hold onto it for as long as they need, and will keep you all as updated as I can.

Awesome, thanks again!
I'll reach out to them if/when I decide to do this mod, it definitely sounds like it's worth it!
When you plug the device in and tune for the first time, it will force you to back up your stock ECU calibration onto the device. What you use that feature for is up to you.
and me too, "if i can *somehow* get this shipped to CA.."
Hi, I just joined the forum - I have a 2016 is200t and just started tinkering (Injen intake and xpedal controller so far; will be adding a HPS turbo muffler, sway bar, and GROM vline soon and hoping to find a black HPS intercooler but seems to be sold out everywhere). Mainly just tinkering for fun.
Thank you for posting your experience with D3. What have your thoughts been on the D3 turbo? Was this something you had to reach out to purchase directly from D3? I didn't see any information on their website.

You're definitely going to want that D3 Tune though. It's a completely different car afterwards. Skip all the other junk in the market.

Hey, nice! Honestly, I can't say anything about it yet. The car will take the turbo perfectly fine, but I don't believe there is not a tune available for it (yet). My car has been with D3 since 12/8/2022 (a few days after I installed the turbo) for additional R&D. I don't think you can purchase the D3 turbo publicly, but reach out to them to confirm.

As well as a few other things, check my part out thread.
