If anyone has an Android phone and would like to test our new phone app, provide us pictures of your GX and using the app please let us know!
It is ready for testing.
You can also datalog from right within the app
(note, for the GX550 as of right now it requires direct Wiflash > USB > Phone)

We have multi-map / map switching development on the way.
By drive mode we have not confirmed yet if we want to do it this way, some customers want it, some do not. It's mixed.
You would just email us and we send you a link.
Currently google requires us to have a certain amount of people use the app and provide feedback before we can publish it. So we are taking that opportunity to get feedback to make whatever improvements people want before we publish it.
I meant with the current 93+trans tune, does anything change if i’m switching the modes? For example on comfort, does it still reduce the pedal sensitivity vs normal, but the rest of the tune is still maintained?
VF Tuner, can you make the software to only display the tunes download options corresponding to the calibration ID that a user has identified and recorded/confirmed in the app on laptop or phone. This will help us users to avoid choosing the incorrect tunes files for download by mistake (unless the wrong ID is identified by users in the first place).

how does that work?
so the mode only affects the steering, AC and suspension?
I assume the transmission shift points and engine power are based on the tune?
Per my understanding, using ECO or Sport modes won't be any different than Normal if using your tunes other than suspension, steering and AC?
That's not what @VF Tuner said before. They said they haven't yet connected the tunes to the modes switch and were also looking into connecting tunes into the cruise control switch like what's normally done for cars that don't have mode switches.
I'm just trying to get official clarification from @VF Tuner , not speculation.
@VF Tuner, hopefully the SHIFT3D is included in this multi map/ map switching update. I like the idea in your post on 19 June that map switching is done via phone, so there is virtually no chance of an accidental switch by a guest driver. It maybe less convenient for those who switch maps frequently but I suppose no one needs to do it while the car is moving.
Edit: Above, I was thinking about the octane and the related transmission maps only. For the OTS maps available and poposed by @TF Tuner below, I would additionally propose that:
For road driving only ("Drive Mode" button), octane/ transmission and MPG (I suppose this is fuel saving, not sure if it refers to regular/mid-grade fuel or not) maps switching is done via phone.
Tow Haul map is enabled when selecting the "Tow Haul" button, and likewise for the Off Road map with the "MTS" button. These should be linked to the current octane map users have selected. This is on OT and OT+. Maybe non OT owners can chime in to see how the arrangement to switch to Off Road map could be on theirs. @VF Tuner may need to clarify how the car behaves in Craw and Low/High if necessary.
"Next up for release:
On the fly map switching. No need to change tunes by flashing. you can shuffle through different maps via your cruise control buttons.
Intended tune plans are (but please give us feedback!)
Map 1: 91/93+ octane Map (using our upcoming octane adaptation)
Map 2: Tow Haul Map
Map 3: Offroad
Map 4: MPG"

I think you are conflating 2 different issues. VF tuner stated that you cannot map switch using the mode selectors. Think of the VF tune as your new "Base" tune. The stock mode switch selections (eco, normal, sport) still work overlayed over the VF tune just like it did over the the stock ecu tune

that's not how it works. those modes change the transmission and engine maps. one of these overrides the other, so clarification from @VF Tuner would be nice.
My understanding was the same as munkeeboi's above. The drive mode just changes throttle response, shift points, and the variable suspension. If you are tuned, your tune should be the new baseline and selecting whatever drive mode should just adjust the above parameters on top of that new baseline by whatever percentage each dictates, each mode is not a separate "tune".

changing drive modes does not change the tune. You still get the full amount of power / boost possible.
Changing drive modes even stock does not change the tune.
What does change (and still does even with our tune) is the shift settings and throttle response. Those changes still exist with our tune as well, just like stock.
The vehicle does not limit boost / throttle / dial back the tune in any drive mode (stock or with our tune). The drive mode options only change throttle response and shift settings

Appreciated the explanation!
@VF Tuner didn't you say you also modify the shift points as part of your tune? Are you saying the drive mode is a layer on top of whatever is programmed?
What would be the difference between the built-in Tow Mode or Eco modes on top of your tune compared to your Tow Mode / MPG tunes on top of built-in Normal? This is all getting very confusing.
Just think of the VF Tuner Tune as your new baseline ECU map.
Best example I can think of is a Valet setting on some cars. When set to valet mode, the tune does not change, but additional settings/restrictions are placed over the baseline tune to retard throttle response. The tune has not changed, but there is an OEM setting that changes how throttle response and shifting will respond.
as for the difference, if VF Tuner does provide the aforementioned maps (Towing, MPG, etc) and on the go map-switching, the OEM modes might be redundant and even limit the already specialized map. For example you are on the mpg map, but choose the sport mode on the GX dial. I would think that once you commit to make the switch to Custom maps through VF Tuner, you would no longer need to use the OEM settings and rely on VFTuners map settings to achieve what you want.
