YotaWerx Tuning Services and Development

I recently tried out BH2.1 and OTT. I landed on OTT for now as I got it semi adjusted to my liking and was getting tired of switching back and forth between tunes all the time lol. Came from KDMax Pro.

BH2.1 Active Duty is what I was running for a bit. I liked it. Shifting was pretty aggressive and felt good - I found myself getting to the speed limit quick and usually going over. Always felt like it wanted to keep pulling when getting up to speed. I had a quirk where it would occasionally stumble at around 20mph. After being told to reflash the tune and resetting all of my values, I was still experiencing it which led me to jump over to OTT. There were a few others that said they also felt the stumble, so if that ever gets fixed, I'll probably switch back over and run it for longer time to see if I prefer OTT or BH2.1 AD. Note, not everybody experiences it, not sure why only myself and a few other do so I wouldn't let it deter you from trying it out.

OTT has figured out the hard acceleration. When you step on it, it gets up and goes-you can feel the added low-end power they claim. What I don't like is the shift table/maps when being light on the throttle. It shifts up way to soon and feels very very similar to stock. I found my truck shifting up/down on my normal route, around 35-45mph. Get up to speed and let off the throttle for a second and I would be in 5 or 6th gear. Then I get back on the throttle lightly to maintain speed and I'm downshifting. I reached out and had my 4th gear shift point raised as much as he could without messing up the rest of the tune. After that change, I've been satisfied with the tune.

Hopefully that info is somewhat useful.

 

I myself as a developer for Yotawerx can't comment on this for the reason that:

1. Personally, I haven't tried and/or scrutinize an OTT tune based on it's driveability and / or data logs. A nice overall health of a vehicle will be yeild by a good tune. This is where I will mainly look at a tune if it's good or not. Toyota's are made to run a million miles and we want to retain it that way while making it drive alot better and more fun.

2. Every tuner has different approach when it comes to tuning a vehicle. There are many variables that I will consider when I would compare a tune.

3. I am a developer not a salesman. I don't have the PR abilities to sell you an orange but it's really an apple.

Nonetheless, if you decide to go with Yotawerx. Don't hesitate to reachout and PM me directly. I will be more than happy to do some slight revisions for your liking.

 

I also have this issue. 2nd gear (when it has happened, Fusion shows 2nd gear) has a pause going around a corner from either a stop or a roll. Always with a soft touch on the gas pedal. Oddly enough, from a stop (turning right) and giving it the frijoles, I do not experience this. Tire squealing is what usually happens with a huge smile feeling the torque before it turns into HP’s, and what Technique mentions where it just wants to keep going. But can’t keep doing that all the time, lol.

I liked KD Max Pro, thought it was a solid all around tune. But AD 2.1 has great grunt now down low. From a stop, the Taco takes off like a cat! That takes torque right? So that’s why I decided to stick with it. To have that power in 4LO, or recovery. Like you mentioned @Technique, it just wants to keep going. That’s a great way to describe it.

I wrote you a pm @Mcbelen, but just thought I’d mention it and I’ll kindly wait for your response. Tom aka @805 Tacoma Tuning has been trying his best to get that sorted out. Hombre has gone out of his way as I’m sure the YW guys have. This tune is for reals folks. The 3.5 is a true sleeper now.

Heard on the streets AD+ is a Tiger launch!!!

 

Glad that you like the tune. However, for the minor issues you have, Our networked tuners are pro active enough relaying and escalating issues to me and we get that sorted out as soon as we can.

*************************************************** EVERYONE **********************************************************

Don't hesitate to reach out to your tuner that dialed in your vehicle. Pretty much they would escalate your minor concerns right away. Also messaging me directly if you are a remote tune or flashing the tune yourselves.

Most of the concerns im receiving is pretty much ISOLATED. One may have a minor issue and one does not but they run both same file. In this cases, we need to take care of it one by one and make sure each and everyone is happy at the end of the day as much as we can (We can't please everyone though )

I just don't know if this would make sense. I would like to forehand apologize if there's a delay sometimes. I am the one and only person taking care of our 70+ tuners' needs every single day (this is across and out of United States) as well as escalations that needs to be resolved. I line up every concern as they come in. This also comes with the continues developments of tunes for other models as we try to make them worthy for the name Blackhawk or Stryker.

The KAIZEN mentality has always been in place for each and every model that we support. WE NEVER STOP DEVELOPING FOR IMPROVEMENT. This being said, All you concerns are welcome!

 

I wouldn't call it a minor issue. If someone is following too close behind, that would create an unwanted scenario or perhaps a negative response by the other driver. The only reason I decided to keep it, unlike Technique, is the torque it delivers down low. It's fantastic.

I apologize as I had a feeling you only delt with those that do their own tunes, or the tuners themselves. I just had to try because Tom has tried several times to rectify the issue. I tried WW, AD, and AD+ with all three having this issue. It wasn't there with KD or the stock tune.

I'll go ahead and talk to Tom again. Thank you.

Almost forgot, the only other thing I noticed is with mountain driving, it doesn't hold 3 or 4th, it will eventually change to 5th, and that kills momentum, so I just use S mode.

 

Because lockup solenoid is not set to be engaged in 2nd on stock models with B04 calibration.
Kdmax has it off in 3rd as well.
I've being telling original "developers " of BH after every update to turn it off for me. They took later model tables in poor into all calibration files.

 

Perhaps they should take you onboard?? I would like this issue done with to feel the torque around corners. That’s one of the best feelings as a driver imho.

 

They need to thoroughly test their releases by folks who knows what to look for and how to test.

 

Creating the the tune from scratch till It became Blackhawk 2.1. I think im sure enough to know if it's a minor issue or not. Like what I said the concerns are ISOLATED. Not everyone has the same issue but basically running the same file. Also, like what @Vlady wants of TC lock/unlock setting, not everyone wants to be set like that (I'm currently working with @Vlady now for his files). If that makes sense. But we are more than happy to make some adjustments here and there and try our best to satisfy each and everyone. (Again, we can't please everyone though)

Yes, feel free to talk to Tom so he can relay your concerns to me and create you a new file to test.

 

Just for clarity, the setting is being asked to turn off is not fully locking/unlocking the converter. The setting activates the lockup solenoid, the converter is in "slip" mode. The full tc lockup is managed by ECU based on many parameters.
When lockup solenoid is activated, the trottle plate closes regardless of your accelerator input. Thus causing a stumble while accelerating.
Disabling lockup solenoid in 3rd has an adverse effect on AT2 temperature (tranny valve body/torque converter temperature). It will go up pretty fast. You are driving in fluid coupling mode.
If you are staying in 3rd alot for towing or driving under a heavy engine load, you need to consider asking developers to review speed values in for 3rd gear to elevate them to avoid engagement and stumbling at lower speeds, say below 35, and engage above 35 to keep AT temperature happy.
In 4th, I do prefer an early engagement to avoid the throttle plate closure in the middle of acceleration, and I stay in 4th for driving under heavy engine load..

The other issues, 3-4, 4-3 shifting needs a focus. Minimal downshift/upshift speeds are not right. A slight accelerator input (1%) is causing shifting.

 

That's a good point. Yes, I do understand and know pretty well the theory of operation of a powertrain. I also do understand ya'lls concern. Like what you just mentioned, some uses their truck for towing or under a heavy engine loads, and some just uses their truck as a normal daily. That's why I consider these concerns ISOLATED because its a really few out of the more than hundreds of trucks that is already running our tunes.

I will continue working with you on your 3-4, 4-3 shifting.

 

Wanted to give a shout out to @Mcbelen and Chris at Tidewater Customs for getting my YW 2.1 all dialed in. Had a minor idle issue (as I posted back in this thread) after a few messages back and forth @Mcbelen got my new files and over to me. Chris at Tidewater got me set up with a loaner VF cable. Got the files/vf tuner loaded up on my laptop and @Mcbelen called me to walk me through everything. After about 75 miles of driving I can report that the idle issues are resolved and the BH2.1 tune still makes the 3rd gen much more “fun” to drive. So is every tune “perfect” ? …. No probably not …. Is the BH 2.1 tune better than a factory Toyota tune … in my opinion… Absolutely! Of course there are other tunes available too. For me it comes down to the people behind the tune and their ability to provide customer service when you need it. With the Yotawerx team that is exactly what I experienced.

 

Thanks for TC edits for 2nd and 3rd. Acceleratoration is much smoother now without dips.
4-3 downshift speed for 0 accel is to high in my opinion. I shared numbers with you. Truck drops to 3rd at 27-28 mph. I have not had any issues so far with 3-4 upshift.
Yes, ideally lockup solenoid engagement should be optimized for a specific speed range to avoid its interference with normal day to day driving.

 

Nice! We are happy that we were able to resolve your concern. Don't hesitate to let us know if there's more that we can do for you!

 

I wonder if that is what i am feeling with OTT, i did not know the throttle closes on lockup, could explain why on the highway if im in 6th under load and need a little more input it kicks down to 5th but for a few seconds it feels with the same throttle input or slightly more less power than i had in 6th may have to test out this tune.

 

You are experiencing a full lockup of TC. Also depends in the throttle limits tuning for gears. Same accelerator input in 6th can produce a different TP in 5th.
If you downshift from 6th to 5th, TC will be in a partial locked for a few seconds and then go to fully locked.
Partially locked state only exists in a very small speed window.
Ideally, we would like to extend the partial lock state and/or activate the partial lock based on the throttle inputs. This condition exists in KDMAX, but at lower speed (<50 mph) for a few seconds. I have not seen a partial lock in speed above 60, unless those tables are altered. However, there is a toll on the AT2 temperature.

I doubt tuners have access to control this.

 

Hey all, my Tacoma is already tuned but can anyone recommend a good contact/resource for a friend of mine who is looking to have his 4Runner tuned in Maryland?

 

Which part of Maryland? I (Quad State Tune) cover the northeast of MD
Jeff Lewis (ChesapeakeProTuning) covers the other half

 

He would count as northeast MD.
