Few performance questions

i have been reading for as much as I have time to for the last few days on many various things just to get ideas and learn and sometimes simply because many people here and things they say and do are quite interesting.

Anyway I’ve only drive my new truck for today being the fourth day. Never once did I have a desire to make a change to my 2015 second gen Tacoma but when I hit the accelerator it’s not the same. Not the same as a Tacoma or any other vehicle I’ve ever been in. It’s somewhat non responsive at all for the first 1/4”-1/2” of pushing the pedal down. It’s most noticeable in startup and also on a slightly inclined road (just enough incline it slows down in overdrive).

After so much reading it seems as though others may be experiencing this also but the terminology many use baffles me with all the abbreviations so unsure what to ask other than is there a simple fix to this?

Also shifting is very strange. Not that it’s bad or lunging or acting weird, but definitely acting like it has two overdrives and can’t figure out which one it should be using if this makes sense.

If anyone has any understandable advice I’d appreciate it. Don’t want to head to the dealer every time I think of something but maybe I’m just not used to the truck or even more so maybe it’s not used to me who knows.

Thanks for your time!

 

Put it in manual shift mode and enjoy

The trans will shift differently

 

1) list the abbreviations you’re having trouble with, those will be answered fast.

2) to develop The understanding you want, prepare to sit and read for awhile. Ask all your things here. See what happens.

3) after page 10 expect this thread to be about muffins or skateboards.


4) I am the low performance fan. Welcome.

 

I’ll try the manual shift mode never considered it really since it’s never seemed worth a flip on any vehicle I’ve ever driven with it. Always seemed computer basically took over anyway regardless what I wanted it to do.

As for abbreviations there are many but mostly in the extremely long tunes topic. Some of you guys are too intelligent for me that’s for sure . I’ll ask though if someone comments directly to me with a term I don’t comprehend.

 

After 10 weeks I’m still trying to figure out this automatic transmission myself.

Please stand in line.

 

The title is misleading, not what I wanted to ask questions about.

Anyway, S4 with ECT on in town no more than 45 to 50 mph is good. The truck actually does have two overdrives as you suspected. S4 will lock both out, S5 will allow only 1 overdrive. Also, dont be afraid to press that gas pedal, the truck will like it.

 

Wake up around 4:30 am on Sunday morning, and take the truck out for a few hours, without shift limiter or ECT button pressed.

Take it nice and slow, whatever the speed limit is or slightly under.

See how much distance you can go without using the brakes, just judicious use of the gas pedal with engine braking.

Every once and awhile, punch it and feel the AT work up through the gears.

Just try and learn how this complex machine operates.

See my signature? That really summed up my feeling when I read it way back when, still holds true, imo.

Maybe all this sounds a little coo-coo, but I thought I would give it a shot.

I have been reading similar threads for more than three years, and I usually can't relate to what others feel is "shift happy", "slow acceleration" etc.

But I haven't owned an AT vehicle before this AT taco, and I have to believe so many years of using the gears with gas pedal has something to do with it.

Whatever, good luck with the new ride.

Cheers

 

The truck shares similar characteristics as many other vehicles. Though this is somewhat new to Toyota.

Our Subraru is equally unresponsive if not worse. I call it Subulag.

Many Yamaha R1s have a similar situation and was also affectionately called Yamalag.

Ultimately, you just gotta get used to it.

 

Don’t be afraid to put your foot in it...being only driven for 4 days the truck has a learning ECU takes a 1000 miles before it’ll adjust to your driving style.

 

Yes I’m sure this is very cliche to say the least especially for those who are active members here. I can imagine this post would fit in well with best exhaust, best lift, biggest tires can fit on stock, etc....

The best way I can explain it is from idle to pressing the gas, it has a delay and somewhat of a lunge. For example 1 this just happened on the way home. While slowing down upon a stop sign I didn’t come to a complete stop. Speed probably decreased to let’s say 2 mph. Upon pressing the accelerator the truck didn’t start ‘giving it gas’ to accelerate despite me not changing the pressure or position of the gas pedal. After a very short delay, let’s say 1 - 1.5 seconds, it lunges and accelerated as it should.

Example 2 would be sitting still at an idle and it doing the exact same thing but no lunge just the delay. Hopefully this makes sense and it just isn’t something I’m used to is all.

As for not being scared to press the pedal, I’m not. Granted during break in times I don’t try to be first off starting line just drive truck normal as I did my previous truck from the day I left the dealership. Some could say I baby it yet I say I take care of my vehicles and don’t push them to limits unless required. If I have to pass anyone on a highway I don’t try to get in front of them to verify my truck has the horsepower but rather pass them with enough speed to get around without slowpoking around. If I’m climbing a hill with 5,000 pound trailer load I’ll definitely not be trying to keep rpms down, save gas, or be worried it’ll shift to a much lower gear when hauling. At same time I’m also in no race when towing either so 60 mph is fine for me unless I’m on a major highway where speed limit is 70.

Anyway my 2015 Tacoma didn’t act as this new one does with the accelerator not even day one with only test drive miles on it therefore just expected somewhat the same results with the 2019.

 

Pressing the gas harder for more acceleration speed isn’t what I’m after. I don’t drive like a granny by any means but have zero desire to ‘show off’ so-to-say. Best I can explain is I drive normal and am no speed demon by any means. If the ecu needs to learn my driving habits id rather it learn how I’ve always driven my vehicles rather than foot heavy on the gas pedal at all times which isn’t me. I typically never exceed 3500 rpm even accelerating onto the highway from the on ramp.

 

I just drive mine now. If I want go faster, I push gas.

 

Sorry but I don’t know what signature is you’re referring to. Maybe due to being on a phone?

As for punching it to go through the gears I’ve done it before also with most all previous vehicles after they’re broke in. Since I’m a responsible adult with a good job and can afford decent and even new vehicles, I try to take care of what I spend a lot of money on. Haven’t had a mechanical failure on a vehicle in over 15 years now and I’m only 38.

Not trying to come off rude with comment because I appreciate anyone and everyone that has any opinion. I’m just not a pedal to the floor kind of guy anymore unless there’s an actual need for it.

 

Same. However this delay then lunge has me thinking ‘what if’ scenarios. Let’s say there’s a major traffic jam on highway and I’m riding bumper to bumper like everyone else. The amount I pressed on the accelerator today was plenty sufficient to take off from zero mph or anything up to 5mph. So if I were riding close to another car/truck in front of me during traffic under same speeds mentioned before then what’s the truck going to do then? This is the main reason I’m asking about the pause and delay of the truck recognizing I’ve pressed the pedal down a minimal amount rather than hitting the gas hard enough to do zero to 60 in 16 seconds. Yes that’s not race worthy but plenty of acceleration speed for daily casual commute.

 

Try sliding your toes a little higher up on the gas. Mine feels the same way if it's too low. Think the pedal rocks on it's pivot instead of moving as much as it should.

 

Thanks I didn’t think of that. Will test tomorrow on way to work and back and see.

 

I really don't know what to tell you. Mine has got 30,000 miles on it. I just drive it. There are lots of variables even with other vehicles.

 

interesting trick.

still no mention of OV Tune, eh?

 

That’s a last resort by any means for myself. I read on that topic for several hours and even went into the website and read some more. It’s honestly so much information that I would be willing to bet most that install it don’t understand it either. However, the guy or group of folks that came up with are definitely intelligent people and very persistent. If I were to buy a tune then I’d have to say these guys seem like they’re the best type of company there are and that’s small and they care.

 

Peak torque is at 4600rpm so if you spend most of your time at 3500 or less it will feel like a stone. The best way to get peak torque lower in the rpm band is with a set of gears. Most guys are going tune but theses trucks were geared wrong from the factory imo.
