Overland Torque Tune (OTT) by Overland Tailor

Cruise Control, both Radar and Normal, function as stock, however, because this tune makes better torque and HP below 3500 rpm, the OTT tune does see less shifting and jerkiness vs stock tune when in CC.

OTT, especially the “GS” variation, will hold 5th and 6th gear much better than OV2.0 and stock. Yet the shift points on the tune will still give you predictable downshifts to 4th and upshifts back to 5th when you need it without hanging in 4th like other tunes on the market. Out here in the mountain west, OTT is by far the best balanced tune I’ve tested for “hills”.

There is also a non-GS option that is better focused at maintaining peak torque, it does shift more often, but it also maintains better torque. So talk to your tuner on which variant is best for you, or even better, try both and decide for yourself.

 

Very questionable when this is someone’s 1st and only post.

 

Appreciate your input. I figured your clients would have some great real-world feedback from their travels and experiences out here in the "hills".

 

Is this tune only flashed by your distributors, or do you sell the file only?

Anything done to 4hi and 4lo?

 

Are you looking for some of the Toyota nanny features to be reduced in 4H/4L? Such as 1st gear throttle limitations?

 

Not necessarily the nanny features, but mainly throttle sensitivity/response.

 

Thank you. Unsure what "GS" is referring to... however...
I like, "predictable" in regards to the trans. I saw on the site, locking out 6th in ECT, etc

I am not a fan of autos, so I tend to be incredibly critical.
But, I am NOT the only driver of this truck. So, compromise it is.
Every complaint of those truck has been the transmission... stock, it shifted like a drunk, that never drove a manual, trying to shift an 18spd truck...

And the cruise question, is because I set the cruise last summer in driving down 59 in Alabama... and it certainly felt like the truck dumped the tune. Never shifted right, until I got home, and reflashed.

Other than that time, I haven't bothered with cruise much in the 4 years/40k I've had the truck.... was fking obnoxious...

 

The throttle selected by the customer applies globally for both normal and ETC mode. VF currently doesn’t have the ability to change throttle only when in 4Lo/4Hi, except with the use of ECT button.

4 throttles are offered for OTT:
Lite - close to stock
Mild - increased, linear and smooth
Medium - further increased, still linear and smooth
Spicy - just keep turning up the dial, but still has smooth initial punch

Throttles move in pairs for ECT:
Lite has Mild ETC
Mild has Medium ECT
Medium has Spicy ECT

Most people that want a lite throttle probably don’t want a Spicy ECT, but mixing and matching is an option. Super Spicy exists if wanted. Another popular mod for heavy trucks that actually wheel is a Medium normal mode and a lite ECT. This allows the owner to have a peppy truck around town, but then when it’s time to crawl and tip-toe around boulders and ledges, use ECT for a soft touch. OTT has tons of throttle options.

 

Are you sure about this? The reason I'm asking is because I'm not happy with too sensitive and not responsive enough with the tunes I've tried in 4lo. The tunes' throttle were very different from each other in 4hi/4lo and neither tune was on ECT. So I was hoping this one would be in the middle somewhere.

 

The only throttle maps that exist are normal (D) and ECT. There are no specific 4Hi or 4Lo throttle maps. Having too much tip in can affect 4Lo by a significant amount, especially if you have different gears. This is why they suggested your ECT button have lower tip in values specifically for 4Lo driving.

 

Our tune is rather unique among the 3rd Gen Tacoma offerings, in that our approach is a bit different than most of the other tuners in the market at present time. As mentioned elsewhere on the forum, one of our key targets for our tune was having precise control over the throttle body relative to the pedal. The way we control/map the throttle on our tunes gives very predictable and consistent output regardless of what transfer case setting you're in. The approach most others take provides them a benefit or character to their tune that we were not necessarily after. We're not saying the way others do it is wrong, just two ways (or more) ways to skin the cat..

As @ktbell444 has stated, there are no specific 4Lo maps that define the trucks behavior when in 4Lo aside from the throttle limiting tables.

I'm quite confident you'll find the behavior and control of OTT very refined in 2Hi to 4Lo. Speak to your local tuner and ask for a test drive.

 

What ^^^Karl says. 4Hi throttle should “feel” the same as 2WD D/S and ECT. 4Lo, due to the torque multiplication of the transfer case, magnifies the throttle changes. Again, if you want a peppy drive around town and in normal 2WD/4Hi, you can get a tune with a more aggressive throttle in D/S mode, then we can set ECT to provide a “lite” throttle to be used when in 4Lo. Really, on any of these tunes there are infinite throttle choices. Finding a tuner that will work to get you exactly what you want is key.

vF tuner is working on a 4 way map switching feature that will allow more options than just ECT. But to date, that feature is not yet available.

Help us understand more of what you want. As what is available is a very wide spectrum.

 

@ktbell444 @JustDSM @BortisYeltzen

Thank you for the info, sirs! But it seems like your tune is only available through tuners?

 

Reach out to @Boltripper and he can take care of you if you want a DIY.

 

Send me a dm and I’ll get you sorted. With regard to 4lo I’ve got a 1600lb Khaya Camper that I haul and crawl with in 4lo.

Well be able to work together to get you a 4lo throttle that is perfect and dialed in for your setup if something off the shelf doesn’t fit your needs.

Best,

john

 

Hey @JustDSM

I sent you a few texts and an email early this week and have not heard back. Did your contact info change?

 

Asking some electrical wizards here.. having a feature like the ECT button and offering a specific throttle tune like say “crawl” which gives ultra low pedal sensitivity but instant reaction would give the best of everything for high or low range.. now the question is, could a switch be added and a power feed to an ECM pin on a truck without ECT, specifically a manual truck?. Would the file still be programmable even if it didn’t come factory on the MT ECM?. If so, that would be an awesome mod to incorporate for off road 3 pedal wheeling.

if all I needed to do is add a power trigger to an ECM pin, to allow a specific throttle setting, then it would be heaven for me..

 

there isn’t anything like that I am aware of. You could always add a pedal commander and turn it on eco mode for wheeling and then disable it for everyday driving.

 

Over the weekend I flashed OTT 7.0 on my truck. I installed the mild-medium version per John's suggestion. For the record I have a 2018 Limited, all stock. My previous tune was Nexus +P and I'll try to include some comparisons to that. I also had an earlier version of KDMAX but no experience with the current versions. I've got about 700 miles on it now.

Short comparison - if you want a sporty tune go with Nexus or kdmax. If you want a solid, truck oriented tune OTT is best.

My observations:

OTT tip in and acceleration are very, very smooth. Nexus is like having a turbo, fast and quick then some extra kick to it as you press the pedal. OTT is very linear and predictable. Acceleration is good, gets you on the interstate with no sweat. You feel the extra torque and power over stock and ovtune 2.0.

Shifting is spot on, I never feel like it's sluggish or shifting early, or holding on too long and revving too high. When needed it downshifts accordingly in the rolling hill environment of east Tennessee. Nexus utilizes torque lock more than OTT and shifting is less apparent as there are "Half steps" between staying in the current gear and downshifting. Again if a sporty performance is what you are looking for Nexus has it, OTT is solid shifting at the appropriate times, like a truck.

Stop and go city driving follows the descriptions I've already given above. Interstate driving between 75-80 feel about the same between the two, cruising is effortless.

Yesterday I did a 500 mile round trip from Knoxville to Decatur Alabama, just outside Huntsville. This is a rolling hill 1/2 interstate, 1/2 four lane 55-65 mph with some stop and go trip. This pic is from a segment on the trip down, part 75-78 mph on the interstate, and 60-65 on the four lane. I know there are those who don't believe some claims on gas mileage from various tunes. OTT delivered this:



Towing a 2500 pound boat back home I averaged 13.5 mpg and as expected uphill was a struggle sometimes. My towing experience is limited so I don't have much history for a comparison.

I forgot to take my OBDlink so I cannot comment on transmission temps or any other technical info.

To wrap this up OTT is a professional organization, contract and all, and very helpful along the way. Quick response to questions and provided recommendations. John was a pleasure to work with. The company and tune give us another choice to improve upon stock and ovtune.

If you want a strong, solid performing truck like experience give OTT some serious thought.

 

Nice review. The question the reader is left with is: what tune are you going to run now that you’ve tested all these tunes?
