Wife asked me today when we are getting this on our new to us 2022. I think I am impressed by her asking.but know nothing about it.

Thoughts on this tune?

I'd be interested to hear as well. I had a similar style tune done on my 2019 Tacoma and it made a noticeable difference, but I don't think my 2015 GX exhibits the same behaviors that made me want the tune in the Tacoma.

Following and wondering if this is what our 23 gx needs in the mountains. Driving it in Utah it seems very underpowered and sluggish. Literally need to punch the accelerator down on steady mountain highway driving uphill.

Is this something the dealership there could/would do without compromising the warranty? This is our 2nd gx and the previous 16 seemed similar iirc.

It's a feature, not a bug

Had not heard of this so I wasted some of my employer's time researching this morning. Planning to drive a 22 GX with BFG 265s to Colorado this spring and would like a bit more torque.

Just had the OTT tune installed on my 2022 GX460. Honestly, most bang for the buck mod. should have done this on day one. Will now be selling my Shift Power.

Why is the OTT tune better than a throttle position remapping device? I now have experience with both and here is why:
* OTT actually improves drivability around town and on the highway. Improved shifting allows for more subtle accelerator pedal modulation. Don't have to push to the floor to get the transmission to respond. I had to use a more aggressive throttle remapping with the Shift Power to get the transmission to feel responsive while underway (+40% linear). On my stock GX, the mild throttle remapping on the OTT tune was sufficient. Throttle is now less touchy.
* OTT throttle remapping is in the forward Drive only. Maintains factory mapping for Reverse. Shift Power and other like hardware remapping devices are on in all gears, forward and reverse.
* Huge improvement on a stock vehicle. If you are running larger tires with greater rotational mass, I would expect the drivability improvements to be even greater, especially with more aggressive throttle remapping (mild, medium, spicy, and extra spicy remaps available).
* Modest performance improvements in terms or torque and HP. Doesn't seem like much gains here, but it was enough that my GX downshifted noticeably less on long highway climbs, holding gears longer and maintaining speed without needing to downshift. I attribute this to torque improvements.

Hey guys,
I know that this post is kinda old, but I thought Id post an update on here regarding an OTT.
Last week I got the OTT done on my 2017 GX. The rig is currently on a 2.5" lift and 34" tires. After installing the lift and new tires I noticed that the rig was definitely more sluggish in accelerating and it had trouble trying to find the proper gear for the cruising speeds and accelerating speeds.
My normal highway cruising speed is about 75mph. So before the OTT it was a bit of a struggle at times for the rig to maintain that.

Now last week I got this tune done and the difference is immediately noticeable. For throttle response turning I went with Mild for now. I do kinda like this setting. It gives a throttle response that is better than the stock response rate, but not overly aggressive. (Which helps my heavy foot not go out of control. lol).
The shifting is definitely smoother than previously. I was able to get up to highway speeds without the transmission struggling to find and keep the gear it wants.
At low range it feels a little more torquey as well.
Im very pleased with this tune and it was a definitely worth it.
If your running larger tires over 33", this is a good in-between mod without having to drop a lot more money on re-gearing.

The opinions seemed very positive everywhere I looked as well.

Was hoping to get some info on pricing, where can it be found (appears you have to take it to a shop), and how does it effect warranty?

I just emailed the retailer for my area with almost the exact same questions.

There is a DIY option as well, I'm definitely going to look into that as I'm pretty comfortable with the idea of doing it myself after messing around with bootmod3 on a BMW.

Never heard of this one. Now I want to do this to my 4Runner!

Just went down the rabbit hole about this tune and seems like good bang for your buck without putting your engine at risk.

I have the OTT tune for my 2014 Tacoma. I have larger tires and re-geard, and the tune helped with shift points and helped everything play well together.

If you're in DFW, Alex Link is your retailer.

So it sounds like somewhere around $500 is the going rate - is that what you're seeing?

That's the going rate for my year GX in Denver.

Around there I think. Saw one site that said around 700.

Thoughts on the warranty part, anyone?

IMO you should assume a dealer can see if the ECU has been flashed even if the tuner says you can flash it back to stock. And you should also assume that any issue that could be tied to messing with the ECU in any way will cause warranty issues with the dealer.

I try to only tune or heavily modify cars that are out of warranty, just not worth the hassle of potentially very expensive issues. But I will say that I'd be far more likely to trust the reliability of a tuned Toyota/Lexus vs. something European or American, so its a risk I'd be more willing to take.

I tend to agree. I know for a fact they can see it. Probably won't do anything to ours right now anyway.

I know for a fact VW will deny warranty fixes on tuned cars, even on parts they had to carve out extensions for due to high failure rate.

I had my Tacoma tuned at 26k IIRC, but of course no warranty items on it so I can say what Toyota would have done.

Yup, seems to be the case and I'm well out of warranty.

When I do it, I likely go with the mild tune based on my research. Although medium seems to get a lot of love too. Haven't seen anyone do "spicy" and not trying to turn the SUV into a dragster...
