Viktor G Tuning

The TRD SC is a rebuild from superchargersonline. It was supplied with a Magnuson fit kit which included VF Tuning. The VF Tuning requires some sort of registration code, but it hasn't emailed the code to me. At this point, I'm willing to ditch the VF tune and go with whatever canned tune to get it running.

 

Wow, I went from being upset with myself for missing this thread, to happy there was a potential solution to a tune, to sad it was not to be, all in 5 minutes! lol

I'm a small 1500 miles/23 hour trip away so if/when you are offering in person for a NA FFV 2013 Sequoia I'm interested!

 

If you get HPTuners MPVI2 and 4 credits, I could write a tune for you. Or you can call a Toyota dealership and see if they will flash a TRD S/C tune into it for you.

 

The Toyota dealers here won't do it unfortunately. If VF Tuners doesn't get back with a resolution, the performance shop has the HPTuners MPVI2 and I will purchase the 4 credits necessary. What do I need to do from there? Or can you call them with the phone number I sent you in the PM? Thanks for your help.

 

PM sent.

 

Adjust the shift points with the tuning software.

 

We can talk about it, I could do a NA tune remotely if you want, I am going hunting for 4 days late tonight and will not have phone or internet service. I can message you next week if you want a tune. Thanks.

 

Going to your island? Yes please & happy hunting!

 

Is this the right kit (plus 2 credits)

No, need 4 credits.

That is the MPV12 (non plus) with 2 credits. So I'd need to buy two additional credits.

Viktor said the MPV12 & 4 credits.

 

MPVI2+ replaced the MPVI2, either one will work. I purchased directly through HPtuners to avoid confusion if there were any issues. You need 4 credits for Toyota Tundra.

 

Ordered an HP Tuner MPVi2+ to get a tune.

It will look great with my Orange Virus and EcuTek tuners.

Hey same I like the HPT since at least there is customer support and it works with my truck and doesn't need updates because somehow it stopped working with my truck

 

I really want to get this moving forward with my SC install, but they still don’t have anything for the 2019’s yet, do they?

 

Not yet:

 

@ViktorG do you mind updating your first post to show which tunes you have available and maybe a timeline of which tunes you’re working on? That way we (those that are waiting for the goodies) can quickly see where you’re at and not have to repeat the same questions

 

Viktor G tune is one of my favorite mods, truck runs awesome, noticeable improvement in fun to drive. Truck is tuned for 87 octane, been places where that was only option. Tow/Haul raises shift points to 6250 rpm and is a little spicy. Wife took this yesterday morning on my Mexico test loop, but it was too busy due to holiday for research past 3rd gear. 8,000 pound truck on 37’s, 5.29 gears with Grip Pro. Have to feather throttle tiny bit on launch due to spring wrap/wheel hop.

Magnuson is making it right and sending the correct stuff for me to get the tune installed. Thanks.

 

Got my truck tuned by Viktor, the difference is night & day! Also, I learned, the truck thought it was running on 85% E85 although I never used it.

Viktor's response time was amazing, his knowledge and kindness are epic and I can't thank him nor sing his praises enough!

It feels like a different truck, seriously, better than the Tundra on OVTune with Doug Thorley long tubes and a full dual exhaust.

 

Thank you for the kind words!

 

Hi all, I have finished all of my prior tuning obligations and have revised my billing structure to reflect the time that it takes to do the whole process. I am once again doing remote tuning on 2007-2018 Tundras and Sequoias! I have updated the first post with the below information to keep you up to date.

Please read the following FAQ to understand exactly what I am offering. If you have questions that are not covered below, please message me. Thank you.

What is custom ECU tuning?
The engine ECU contains software that controls the various parameters under which the engine runs. These parameters include achieving the appropriate balance between fuel consumption, power, torque, fuel emissions, and reliability. In seeking this balance the factory ECU software settings often do not prioritize power or torque, which means it is possible to increase the performance of the engine by remapping the ECU. In addition to that, there are many throttle and torque limits built into the factory ECU maps that choke the engine performance in many circumstances.

Is this tune achieved with a piggy back device or a stand-alone ECU?
Neither. What we offer is custom tuning of you original factory Toyota/Lexus ECU using HPTuners hardware and software. There are no physical changes done to your vehicle other than software changes to the tables and parameters inside of your factory ECU.

What ECU parameters can be tuned/remapped?
Rev limit, speed limit, air fuel ratio (AFR), ignition timing, tire size (does not affect speedometer readings), final drive gear ratio, throttle response/sensitivity, transmission shift points, throttle limits under various driving conditions, disabling the limp mode with air injection pump fault codes, transmission line pressure, torque reduction during gear shifts, camshaft variable valve timing (VVTi) and more.

Will I be able to see the tune parameters myself to see what changes were made?
No, we sell a tune that is custom calibrated to your vehicle and the way you drive it. We do not sell the actual data within the tune or any of the calibration tables. That data was developed over many hours of dyno tuning and road testing, and is considered proprietary intellectual information.

How does the remote tuning process work?
You will need to confirm with HPTuners that your particular vehicle and ECU calibration ID is supported by them. After that, you will have to purchase the HPTuners MPVI2 hardware and install the VCM Suite software on your Windows laptop. Connect to the vehicle and confirm that you can get the stock calibration file for it from HPTuners. After that, you will contact us to let us know the model and year of your vehicle and fill out a questionnaire detailing your driving style, vehicle modification information and the changes you would like to be done to your ECU parameters. You will send us the stock calibration .hpt file for your vehicle and we will build a custom tune for you to flash into your vehicle’s ECU. You will take the vehicle for a test drive and data log multiple ECU parameters using our Channel Config file to make sure everything is working properly. If there are any adjustments that need to be done, we will do them at that time and send you a new file for you to flash into your ECU again. The whole process will take from a few days to a couple of weeks if retuning is needed.

How does the in-person tuning process work?
You will let us know the model and year of your vehicle and fill out a questionnaire detailing your driving style, vehicle modification information and the changes you would like to be done to your ECU parameters. You will come to us and we will connect the MPVI2 interface to retrieve your stock file. Once we confirm that your vehicle ECU is in fact tunable with HPTuners, you will pay us for the tune (we need payment upfront, because once we unlock your ECU with our HPTuners credits, those credits get used up and are not refundable). After that, we will build a custom tune for you and flash it into your vehicle’s ECU. We will take the vehicle for a test drive and data log multiple ECU parameters to make sure everything is working properly. If there are any adjustments that need to be done, we will do them at that time and reflash your ECU again. Once we are satisfied with the tune performance, you can pick the vehicle up. The whole process will take somewhere between 2-4 hours.

Can the tune damage my ECU?
The tune itself cannot damage the ECU, but the process of tuning can. If there is an interruption while the ECU maps are being overwritten, the ECU may end up in a partially erased state (bricked) and unable to function. The interruption could be due to the vehicle battery voltage dropping too low (such as if the battery charger that is used during the reflash failing or getting unplugged), the laptop that is being used for tuning getting unplugged or having the battery depleted, the Windows software or the HPTuners software crashing during the reflash. If your ECU does get bricked during the in-person tuning process due to an issue with our software or hardware, we will work with you on getting the ECU sent out to HPTuners to get unlocked and programming it to your vehicle at our expense. If your ECU gets bricked during the remote tuning process due to an issue with your software or hardware, we will work with you on getting the ECU sent out to HPTuners to get unlocked and programming it to your vehicle at your expense.

Do I need to do anything special to prepare my vehicle for tuning?
For us to tune your vehicle it has to be in good mechanical shape and running smoothly. You have to have the proper octane gasoline in the tank before we tune the ECU for that particular octane. You should have the basic maintenance done on it, such as a reasonably clean air filter, fuel filter, injectors and mass air flow sensor, spark plugs that are not worn out and were replaced at the proper interval, no misfire or other fuel or engine performance related fault codes in the engine ECU. In many cases you will be required to install an aftermarket wideband AFR gauge on your truck if it is supercharged before we can tune it. This is due to the factory A/F sensors only being able to read down to 12:1 AFR and that is way too lean for the supercharged engine. Also, on most flex fuel vehicles you will lose the ability to run on E85, and will only be able to drive on gasoline (unless we tune it to run on E85 only). The flex fuel system on these trucks is quite rudimentary and issue prone, so we prefer disabling it to prevent any problems from creeping in such as the truck thinking it is full of ethanol while it is in fact filled with gasoline and vice versa.

Can the tune be detected by the dealership and void my warranty?
The fact that your truck is tuned is very unlikely to be detected by the dealership because the ECU calibration ID stays the same. The only way a tune could be detected is by observing things such as higher than stock rev limiter or speed limiter. The chance of the dealership staff operating your vehicle under those conditions AND noticing that it is outside of stock parameters is almost zero. Even if the dealership knew that the vehicle is tuned, they would have to prove that the tune is directly responsible for the failure you are trying to get warrantied.

What would happen if the dealership updated my ECU calibration as part of a repair or recall?
Sometimes the manufacturer will release updated ECU calibrations to address an issue that they find with the vehicle. In case the dealership does update your ECU calibration, the custom tune in it will be overwritten back to stock. In that case, you would have to get the ECU reflashed again to the custom tune parameters. You would have to pay to unlock the ECU again and have your custom tune flashed into the new ECU ID.

Will the tune improve my fuel economy or make it worse?
In general, the custom tune will not have any effect on fuel economy. This is because under normal (closed loop) driving conditions, the ECU is trying to target a stoichiometric air/fuel ratio (AFR), which provides for a good balance between emissions and fuel economy. Our custom tune does not change any of the engine parameters during closed loop operation. Where it does change things, is under load during moderate/heavy throttle application. While some people may experience a change in fuel economy, it is simply due to the fact that they end up applying the throttle more to feel the newfound power of their vehicle more often.

Will your tune make my vehicle engine or transmission wear out faster?
There is a small chance that it might, depending on what specific things you request with the tune. If you want changes done that will dramatically increase the rev limit of the engine to let's say 7000+ RPM, the vehicle speed limit or changes that will affect transmission torque reduction on upshifts for example, those changes could marginally shorten the life of some powertrain components under certain conditions. Also, if you ask us to make a tune for 93 octane but then fill up with 87 and beat the crap out of the truck, it may cause issues. If you keep most things stock, and just optimize fuel and timing tables or remove some throttle limits, those changes are unlikely to make anything fail sooner, and may instead add longevity to your engine since now it is operating under more favorable conditions.

Do you provide any warranty with your tune against mechanical failure or check engine light setting?
We do not provide any mechanical warranty in case of engine, transmission or other failure. Since your vehicle is a complex machine with hundreds of mechanical parts working together in unison to make it operate, we cannot predict when a part of that mechanism will fail. One thing that is certain is that eventually something in your engine and transmission will wear out, whether that vehicle is custom tuned or not. We will not be held liable for any mechanical failure regardless of how soon after tuning that failure happens.

What is the cost to have the tune done?
The HPTuners MPVI2 costs $250 USD and the MPVI2+ costs $300 USD. You will also need to buy 4 credits from HPTuners to unlock your ECU and be able to write a tune into it. Our remote tuning pricing will vary based on your vehicle setup, whether it is NA or supercharged and your skill/experience with using the laptop for tuning and using the HPTuners hardware/software package. A large portion of the process can be spent on explaining the customer what to do and how to set everything up and walk them through every step from the very beginning to the end. If you figure out how to do most of the setup, reading, writing and data logging yourself, that will save us a significant amount of time and therefore money.

How much horsepower would I expect to gain from your tune?
Since every vehicle is different, it is almost impossible to answer this question. There is also quite a bit more to custom tuning than just raw power numbers. There is a lot of optimization that can be done with transmission shift points, torque management, engine torque limits, VVTi angle adjustment, throttle response etc. These changes will result in your vehicle being much quicker, even though the power may not be increased dramatically. As an example, on our NA truck running 87 octane fuel, we were able to shave off about 0.6-0.7 seconds from the 0-60 times. On a stock TRD supercharged truck, we picked up about 75 whp from the tune alone!

@ViktorG maybe I missed it, but are you doing the remote tuning for supercharged flex fuel trucks at this time?

 

Yes, I can. If it is a stock Magnuson setup with green injectors (not stock flex injectors), stock Magnuson airbox and stock headers, you will not even need a wideband AFR gauge for me to do it.

 

@ViktorG Welcome back!!

 

That's exactly what I'm running (stock Magnuson setup with the green injectors, stock Magnuson airbox, and stock headers). I do have the TRD dual exhaust.

I do not currently have an afr gauge which was my next question. If my current set up works for you and you're willing to do my remote tune I'll go ahead and get the HPTuners MPVI2+ ordered, just let me know.

This will be somewhat of a learning curve for me as I haven't done any data logging before, but will do my best to make the process as painless for you as possible. Let me know if you're up to the task!

 

Yes, we can do it . I will PM you with details shortly.

 

Great! Thank you.

 

Christmas really does come early!!!!
