Have you turned ECO mode off?

I’ll have to try this, she drives our GX 99% so not a big deal but I hate the lame shift points.
Took the GX up in the mountains today, used the Sport mode there & back…very noticeable difference 👍🏻

Thanks folks, I really didn’t realize you could use Sport without manually shifting…some pictuhrs just because

From what I remember reading, the transmission adjusts to the driver. I really disliked mine when I first got it. It did adjust and deals much better with my driving constraints. I had only ever had one other daily driver with an automatic so I was even more critical than some.

It's also key to shift into sport mode when you want to bypass the throttle PID loop. It gives your direct 1:1 throttle response vs a manipulated, "wafte along like a fart" throttle map.

I have kept it in sport mode on a few of my relaxed back country jaunts and not seen any mileage hit with it either.
 
My 2011, the ECO light comes on and off based on my throttle input to indicate "efficient" (😂) driving. My steering wheel menu system has no option to turn it in or off.

My 2013 RX 450h hybrid, however, has a true ECO driving mode, with muted throttle response, sloppy steering, and wimpy HVAC fans. Yay....
Exactly. GXs don't have an ECO "mode" like the RX and other Lexus vehicles have. Our "ECO" is just and indicator that your accelerator isn't on the firewall. And it takes a LOT of stomping in my experience to get the ECO light to turn off. I think mine turns off after I get over 85 or 90mph, or whenever I go WOT. Other than that, it let's me know I'm an environmentally conscious, carbon neutral, citizen of the world.

Clearly the light was a bad attempt to make the GX and it's 13mpg look environmentally friendly. Kind of like Toyota's "forever transmission fluid" lol.

From Lexus: Just an indicator.
The ECO Driving Indicator is designed to inform and encourage drivers to operate their vehicle in an Eco-friendly manner. The “ECO” light and zone display let the driver know when the vehicle is driven in a fuel efficient way, based on driver acceleration. The green ECO light is illuminated when the vehicle is being operated in an eco-friendly manner and will automatically turn off when the zone of Eco-Driving is exceeded. The ECO Driving Indicator Zone Display (shown as a bar graph) can be displayed in the TFT multi-information display to inform the driver when they are in the ECO zone. You do have the option to activate or deactivate this green ECO light by using the “customize” screen on the multi-information display, accessed via the “DISP” button on some Lexus steering wheels.

I need to check again but often found a correlation between AT torque converter lockup and the light being illuminated. An alternate use if are without a gauge for AT temps.

I definitely experienced this in my Tacoma and 470. If I unplugged the battery for 10 mins or so, it would noticeably reset the learned shift points. Haven't messed with it in my 460 yet.

My 80 series got really stupid every time I disconnected the battery. Shift points would be a mess, it ran rich, idled high, and all sorts of other symptoms. The worst part was that I first experienced this after swapping my ECU for a used unit. I thought I'd broken something, or bought a bad example, but the good folks here told me to be patient while the truck relearns how to run properly. A couple days later, it was right as rain.

I also fondly remember the fellas at Sport Compact Car Magazine gaining a few HP on the Dyno after flogging the wheels off their WRX for a few thousand miles back at the turn of the century. Made me want a Blubaru even more at the time.

If that were the case, the eco graph would register something. Mine NEVER did while the eco light was on.
As I've said a number of times in this thread, I've read the manual on this subject a number of times, and as everyone keeps saying "it only is a light" (although , I wonder how many have actually tried comparing the performance rather than just parroting the what the manual says). I understand what the manual says it doesnt. My experience doesnt comport with what the manual claims.
 
OP: What throttle controller did you install? Have you removed it from vehicle as well?

I really have nothing technical to add…. In nearly 8 years of ownership I’ve never experienced ECO mode on or off having a performance effect nor saw any other reports here or on other forums as it having an effect. I have many different FSMs and never came across any documentation stating it did as well. Sport mode does have an effect so I could look at non-sport as ECO mode I guess (light on or off).

Those creating some of the new performance maps would be able to settle the case of any coded changes that occur with the light on or off.

Maybe I could test it since I have an aggressive tune from YotaWerx that changed the mapping. What's the best way to accomplish a test to ensure accurate digestible information?

The trouble is, you mentioned three different things in your original post, and haven't been clear about which you did when, or what your current setup is:

-turning off the eco light
-driving in sport mode
-adding a throttle controller

Most of us are pretty sure that if you a) didn't have a throttle controller, and b) drove in "normal" rather than "sport" mode, there'd be no difference in performance with or without the eco light turned off.

Placebo effect?
 
My mixed driving over the past two tanks yields the same 16.1 MPG over 306 miles and fuel light on (24 miles remaining). First tank was with ECO on, second was ECO off.

If it supposed to do something, mine is broke...and I don't care.
 
This all reminds me of Porsche and its shift light arrow lighting up in the 70s and 80s trying to get you to drive your 911 slowly to conserve fuel.

I also hate the eco light and any other dash lights being on unless something important is happening
 
You mean like this? ECO line goes up when engine goes vroom. Enough vroom and ECO light turns off.

ECO light on:
full

ECO light off:
full
Exactly!!
I've never seen a light on the dash, e.g.: an ECO idiot light within the dials. It's only in the center and one has to scroll to it or leave it there. I keep the outside temperature displayed all the time.

As someone who has only had 2 cars that didn't have 4 cylinder engines i keep it up as a reminder to chill out. I need lots of those reminders. I am too high strung as it is.
