As driving with higher revs this update is useless performancevise
 
Do we have any idea which dealerships are offering this? The PH article implies that owners are being written to, I assume only those with a connection to one of the 10 pilot dealerships?

This is just a misunderstanding from it being announced on Facebook by a dealer.

If I read this right, you get the option for slightly changed throttle, steering and front/rear balance, all set for you at the dealership, not owner configurable, and a slight torque boost in a very limited rev range.

Err, no thank you.

If it was giving a torque boost across a wide rev range then maybe, but I guess that that would impact the emissions etc.

Ah well, never mind.
 
Maybe it was a german rule and the UK dealers will flash them as often the customer wants. On the other hand, how often do you want to erase the progressive to conserative settings? The effort would be below 30mins so the dealer can charge it as a service if a customer is curious to test every configuration. :D

Shame they won’t let us default auto start-stop, lane assist, etc. to OFF. I’d gladly pay a grand just to have a clean, dongle-free solution built in. That’s how you truly fix this platform once and for all. Fight me.
 
To be fair, that's been mandated by emissions and insurance, as opposed to the manufacturer.

A lot of these so-called “safety systems” were never even mandated in many GR Yaris markets – but that’s not the real issue. The issue is that even when they are mandated, they are NOT required to default to ON at every startup. Why? Because plenty of other cars with the same regulations don’t.

Take the G80 M3 or the Civic Type R – both sold in the UK. Neither forces auto start-stop, lane assist, or pre-collision to be ON by default. You can disable them, and the car remembers. That’s how it should be. The tech exists – it’s just a matter of implementation.

Toyota really dropped the ball here. And yeah, I get it – some people don’t mind pressing a sequence of buttons like they’re firing up a fighter jet every time they start the car. But for some of us, it’s just lame and super annoying.

Able to solve one problem

 
As slightly annoying as it was at the beginning, after 4 years the several seconds of 'pre-flight checks' are now done without thinking, so personally for me, adding a dongle would just be a waste of money for a couple of seconds saving time. Definitely should have been coded to remember last used settings though.
 
I had enquired through RRG Macclesfield who got in touch with me today. What I found out:

-RRG Macclesfield are one of the (10) supplying dealers
-There is definitely no hardware, software only
-Remaps are installed by dealer using a licence key provider by Toyota UK - perhaps these are what have been referred to a "kits"
-A "permanent" plaque/sticker is placed next to the VIN sticker on the door - this serves as a record that the remap has been applied
-Configurable aspects (steering /throttle response/ F+R bias are chosen by customer and configured as part of map install

I am genuinely interested in the remap but need to be confident that I would notice an improvement in performance before coughing up £1k which is understandably (20nm...) not something the dealer could confirm. I asked if there were any sources that could be approached for anecdotal evidence (Japanese mkt / Toyota) to vouch for bum dyno effect.

I'm at RRG Macc for service in June so with see if there's any more info to go on by then.

Anyone else taking the plunge ?
 
I was invited to a GR Selections event where Toyota brought a bunch of GR Yaris with the different calibrations. All cars had the torque bump, but differing power steering, throttle mapping, AWD control, etc. Slalom, circle skid pad, etc. After driving each car, I sat down with a development engineer and discussed what I thought about the calibration change while they aggressively took notes.

The 20nm bump is very noticeable, even on a stock car. It's essentially the same engine calibration as the GRMN (JDM). With a good exhaust it's more like a 30nm bump, which brings my JDM car to 400nm. I also noticed that power in the top end doesn't fall off as much. Boost carries out and it has more grunt from 3,250 rpm to red line. But this could very well be a JDM thing.

The throttle mapping "high response," which is what I opted for, is awesome on fast winding, but way too aggressive for gymkhana. The "control" is more linear than the stock calibration and what most people doing gymkhana opt for. Below about 3,000rpm, the calibration is the same as stock for all options.

I couldn't really tell a difference between the 55/45 and stock 50/50, but the 45/55 definitely makes the car want to push at throttle application mid-corner than the other settings, so I just left it alone.

People who do gymkhana want a lighter power steering. I didn't like it for fast winding, and certainly don't want it heavier, so opted to leave it alone.



Now, 'the dealer" has nothing to do with calibrating the software in the car. You have to specify what you want (in Japan that's done online through Kinto). Then you tell them what dealer of GR Garage will do the flash. Toyota (the big guy) does the calibration for your car's VIN, and the new calibration is registered to that VIN. Then the dealer or GR Garage calls you when Toyota says it's ready, you bring the car and they simply plug into the car with GTS, and the ECU is reflashed from Toyota with the new calibration. The same procedure as if you were changing the engine controller.

At any time in the future, if the ECU is replaced, the cal file that's flashed to the new controller will be the upgraded one, as that's the cal file for that VIN. You can opt to change it back to original, but again, has to be done through Toyota and then the cal flashed by the dealer, etc.

Came with official paperwork and a sticker in the door by the data plate.

*Edit. Because I only opted for the torque and throttle cal change, it was only ¥88,000. Worth it in my opinion, especially the throttle change, and it's all stock Toyota. Literally the stock calibration for that car.

Thanks for sharing. From your words, it looks more appealing than I usually thought.
 
I'd really like to see an independent before and after dyno run before
