2016 Corolla LE ECO Mods?

[GK13]

So, anything that I could change with the engine or any modifications I can try to do that would help the mpg? I keep my tires inflated to max sidewall, I try to use neutral to coast to my stops and keep from having a lead foot. I do seem to get better FE if I use the cruise control more than just my foot. I have no idea why that is. Maybe the can is smarter than the driver. IDK. I am looking at doing a grill block and maybe smoothing out some area in the car. I kinda know what I need to do but I am trying to see what I can do that will show a substantial improvement in FE.

Stick car or auto? PnG is great for in town and highway, but interstate (65-70mph) it's better to me to use cruise control.

it is an auto 7 speed cvt. incredibly smooth. just no power at take off if I don't push kinda heavy on the pedal. averaging 38 in town and 45+ highway if its flat

CVT has no discrete gears. Keeping RPM low will help. Have you checked the 65+ efficiency mods section?

I have and I am trying the best I can to complete at least a few of those. idk how much they will help though. I'm mainly wanting to see if there's anything mechanical I can do to the engine that could potentially improve efficiency.

Highly unlikely, modern engines are very efficient. The low-hanging fruit will be driving style changes (don't rev it up when accelerating, keep cruising speed low, conserve momentum), followed by aero mods such as grille blocks, underbody panels, smooth wheel covers, etc.

CVTs can be programmed to simulate shift points. IIRC Subaru does that. Aero drag is another place where the savings will come from.

Again, I said this in the other thread you made, but I would not P&G this car because the Valvematic makes it far more efficient at low load than a typical engine, and you only have 1.8L to pull a fairly big car (compared to my tiny sports car). Because of this, its peak efficiency load should be a little lower than most engines (my guess is 70% rather than the typical 80%), and so more modest acceleration will help your fuel economy.

The only mods that I would try are load reduction mods, like an underdriven water pump, reduced electrical power usage, aero, etc. You can buy an underdrive pulley for the water pump for 75 dollars off MWR (I think the 2ZZ-GE pulley is the same as the 2ZR-FE pulley, and they are interchangeable), but you will never save anywhere close to 75 dollars in fuel from that mod.

While you can't have fun modding your car like most other people here, you can enjoy the fact that you have one of the most advanced engines out there that does all the hard work for you

I think that is what I'm stuck on. I want to be able to do SOMETHING to it lol. I feel stagnant lol. I will try not shifting into neutral instead and see how that goes. I don't punch it to accelerate mind you. I am holding it at either 1500 rpm or 2000 if I really need it, and that's all. I really am a relaxed driver. I was seeing that putting the underdrive pulley on could hurt the performance of my air conditioner? I have medical issues and the air is a must. I was also informed that the engine is a 2ZR-FAE engine and not the exact same as the 2ZR-FE engine? Is this true?

Honestly, there aren't a lot of easy and effective mods for many modern engines. Even with something older like my Insight and Civic hybrid, I'm pretty much limited to a warm-air intake. Underdriving the accessories isn't even all that useful, because there's no alternator, and thermal efficiency is already close to 40%, which is actually better than many power plants.
