  • Does using ECT power affect the tune in any way?
    Yes, it does. The ECT button is still essentially a separate map that is activated when the button is pressed. It provides a slightly more aggressive map than non-ECT.
  • What vehicles do you support?
    We have tunes available for the naturally aspirated or Magnuson Supercharged 3rd Gen. Tacoma, naturally aspirated 2nd Gen. Tacoma, 5th and 4th Gen. 4Runner, 2nd Gen. Tundra, as well as Lexus GX 460 and GX 470 with more in development! Visit our Available Tunes Page to see the complete list along with currently supported years and vehicle specifications.
  • Why should I get my vehicle tuned?
    Simply put, because you can get more out of your vehicle! The Toyota/Lexus vehicles we tune all suffer from varying degrees of neurotic shifting (often described as “gear hunting”), lack of power, and terribly sluggish throttle response. These three issues alone are, at a minimum, enough to make daily driving frustrating and in certain cases, it’s enough to make some want to sell their vehicle outright. With tuning, these issues could be easily mitigated, and you can get that drivability that should have come from the factory.

  • What is tuning and what are the benefits?
    A “tune” is a rewrite of your vehicle’s Engine Control Unit (ECU) and if applicable Transmission Control Unit (TCU). Using state-of-the-art computer software, a flash cable, and proprietary tuning files catered to your vehicle’s specifications, we can modify the contents of the data on your vehicle’s computer. The benefits of remapping the ECU through tuning are the engine will have a smoother power curve, a bit more horsepower and torque, and the ability to utilize its available power more efficiently. On the transmission side, the automatic TCM is remapped for a simplified and more predictable shift logic which creates a much-improved drive experience and possible improvements in fuel economy. Manual transmissions also benefit from a reduction in the amount of “rev hang” in between gears, which leads to smoother and cleaner shifts.
  • How is the performance for manual transmissions?
    The manual transmission (MT) Tacoma obviously and thankfully does not have to deal with the shortfalls of the factory programming that the automatic transmission (AT) Tacoma does. While the AT sees a massive improvement due to the remapped shift logic, the MT benefits more from the tune on the motor side. One of the key improvements is the mitigation/elimination of “rev hang” that happens in between shifts on the MT. This helps provide for smoother shifting and easier transitions from gear to gear. Overall many MT owners are extremely happy with the tune and say it's worth the investment because of the smoother running motor that likes to rev.
  • Will the tune accommodate my aftermarket intake and exhaust, and how will they affect the tune?
    The great thing about these vehicles is that the computers in them are quite fast at adapting to the modifications placed on the motor that affect turning air into exhaust. The tunes we supply are designed to run on a vehicle with a factory intake, ignition, and exhaust system. When any of these components are modified, no changes or updates to the tune is needed. Simply put, the computer is intelligent enough to recognize the efficiencies brought to the combustion process from these modifications. It will then make the necessary changes to accommodate them and work to maximize the benefits they provide.
  • My vehicle has a larger tire size and/or is regeared, why is the tune necessary?
    Modified vehicles many times suffer from increased load and drag from the addition of larger and heavier tires, wheels, armor, and other offroad/overland accessories. These vehicles benefit highly from the ECU/TCU changes mentioned above, but the tune can be further refined through throttle response and shift points to help with modifications such as increased tire size and/or gear ratios.* *Although regearing is not required to run the tune, select vehicles can have the tune programmed with 4.88 or 5.29 differential gear ratios in mind. We strongly believe that if you are running the factory ECU/TCU calibration with aftermarket gears that you are not getting the full benefit of your vehicle's new gearing. This is because the tune is designed to assist the aftermarket gears to run optimally through the use of customized shift tables that are specifically tailored to the larger ratios.
  • Is the tune appropriate for stock vehicles or only for vehicles that are modified?
    Everything from stock to highly modified and heavy vehicles will see benefits from tuning. The reason the tune can accommodate such a broad spectrum of vehicles is because it comes in different versions that take into account variations such as driving style, throttle control, and whether or not the vehicle has modifications or additional weight. Stock vehicles that opt for tuning will definitely notice the increase in power and the smoother delivery of that power throughout the rev range. They will also enjoy a more refined and predictable shift logic that is created by the tune. Combine these together and most drivers report improvements in fuel economy and of course in their driving enjoyment.
  • Can you calibrate my speedometer?
    No, tuning does not, and cannot correct for speedometer and odometer inaccuracies that occur as a result of increased tire size or gear ratio changes. These measurements are managed by separate control units in the vehicle that are in no way connected to your vehicle's engine control module (ECM) and transmission control module (TCM). The only way to correct these inaccuracies is with an aftermarket speedometer calibration device which may or may not be legal in your area. Please check your local laws regarding these products.
  • Should I wait to get a tune until after I add armor/more weight?
    No, we think you should tune as soon as possible and here's why. The benefits that you will see when you initially get a tune will still be there after you add weight to your vehicle. Plus, doing a lot of modifications that add weight can take time so why not enjoy the tune while you save for those other mods? All that said, the tunes do come in two variations that take into account vehicle modifications and weight and we can update your tune to a more appropriate version, at no additional charge, in the future if need be.
  • If I haven't regeared my vehicle and I tune it, will it still be effective later when I do regear?
    Technically, the tune for the factory gears will work okay with 4.88 or 5.29 gears. However, to get the full benefits of the tune and your gears you should schedule a tune reflash, which we provide at no additional charge. If you have your gears purchased and a regear scheduled, then we suggest you wait to get the tune until after your gear break in period and differential fluid flush is complete. If you aren't already scheduled to regear (gears in hand or on order and an install scheduled in the near future) then we say get the tune now and enjoy the benefits while you prep for the regear.
  • Does the tune need to be updated regularly?
    Depending on accessible customizations in your particular vehicle's ECU architecture, the tune only needs to be updated if you make an applicable modification to your vehicle, i.e. increase tire size (33”, 35”+) or change gear ratios (4.88, 5.29). Then it is worth reflashing to a more appropriate version of the tune to take advantage of its full benefits. In the event you do change something that requires a reflash we consider those “necessary updates,” and there is no additional charge. On top of that, development on all vehicles is still ongoing. As access to shift tables and additional tune parameters are unlocked on select vehicles, customers will be contacted and given the option to upgrade to the newer version of the tune if desired. For those not directly local to us in San Diego, we ensure that this service is available to you whether you come to us or we return to your area on future trips. We are also associated with YotaWerx Tuning LLC and their nationwide network of authorized VF Pro Tuners if your tune needs to be updated, but you no longer live in the Southern California area.
  • What about Technical Service Bulletins (TSBs) or new software releases?
    First off, as part of the installation process we ensure your vehicle is up to date with the latest factory software prior to tuning. For many earlier model year vehicles, it is unlikely there will be any further revisions to the ECU/TCU software released from Toyota. However, if there is an update that is released, we will contact you to discuss your need for a reflash and schedule an appointment. At that time, we will update both your factory software and tune to the latest versions at no additional charge. Part of the service we provide is staying informed of all necessary updates, including TSBs or software releases that are applicable to your vehicle, so you don’t have to.
  • Is the tune permanent?
    Yes and no. The tune is permanent in the sense that it does not disappear when you disconnect the battery or dissipate in any way over time. Once uploaded the tune is stored in the permanent memory of the ECU. The only way you could lose your tune is if the calibration is overwritten by another stock or aftermarket tune, or the ECU is fully replaced. If this is the case, contact us and we can reflash the tune back onto your vehicle at no charge. The vehicle may be returned to stock programming at any time with another flash upload.
  • What is the process and how long does it take?
    In total, the entire process takes roughly 30 minutes. After verifying your information, we will scan your vehicle to get your factory ECU ID and if necessary, update it to the most recent factory software available for your make and model.* Then we will flash upload the tune with the additional parameters specific to your build onto your vehicle. After flashing we will provide you with a comprehensive explanation on the break in process of the tune and what you may expect as the vehicle learns and adapts to the new software. *In some cases, we may need to identify the vehicle’s ECU ID and then schedule a follow up appointment for tuning, as some ECU versions have yet to be identified and therefore may not be supported at this time.
  • Do I have an AGM battery? / Is there a tune for alternator control?
    AGM stands for Absorbent Glass Mat. These are aftermarket batteries that owners install to get higher voltages, better starter cranking, fatigue resistance from high energy load systems, and a longer lifespan. Common battery brands for these are Odyssey and Optima, along with numerous others. These batteries do not come from the factory on Toyota vehicles and have manufacturer recommendations that state they be charged at a higher voltage (approximately 14.3v to 14.6v depending on the battery) than what Toyota set the alternator to put out. These settings can be adjusted via tuning so alternator output can be increased to match the battery and maximize its efficiency. Available for 3rd Generation Tacoma (2016+) only.
  • Do I need to change the type of fuel I get? / Is there a tune for octane preference?
    Every tune comes in two variations, 87 octane (regular) and 91+ octane (premium). After tuning, when you turn the vehicle off and then back on the computer immediately restarts under the assumption that the tank is filled with whichever octane was specified for the tune. With that said, select vehicles are Octane Learning Enabled, meaning they will adapt to whatever fuel is in them. For example, if you choose 91+ for your tune, and travel somewhere that only has 87 you could safely fill up the vehicle knowing that it would adapt to the 87 fuel and not do any damage. However, it is recommended that as good practice you regularly fill up with whichever octane you selected for your tune. For the 3rd Generation Tacoma (2016+), we personally recommend the 91+ octane tune variation. The Tacoma has what is known as a misfire condition and it has been shown that these misfires occur more frequently when operating on 87 octane. Running 91+ has proven to minimize the condition. For the GX 460 and 470, Lexus recommends premium fuel, so we recommend the 91+ octane tune variation but, we can provide the 87 octane tune if that is what you prefer. Currently we do not have tunes for the Flex Fuel Tundra as there are variances in their tuning needs that are currently still in development and near completion.
  • What is Gear Lock?
    Gear Lock provides the driver with near complete control over the transmission’s shifting by overriding the factory shift logic and turning the “S-Mode” shift setting into a true auto-manual style shift selector. Currently the 2016+ Tacoma, 2020+ 4Runner, and 2018+ Tundra are the only vehicles that can opt for Gear Lock. For the Tacoma, Gear Lock is activated by using ECT and S-Mode together, this otherwise makes ECT mode unusable when not in S-Mode (we are waiting on further development to change this in the future).
  • Will the tune improve my MPG?
    We cannot guarantee an improvement in miles per gallon as every vehicle is modified differently, driven on various terrains, and done so with diverse driving styles. However, on average across platforms customers have reported a 1-2 mpg improvement in city and 3-4 mpg improvement on open road highway trips after tuning.
  • Can the tune be detected by Toyota or Lexus? / Will the tune void my warranty?
    Generally speaking, these tunes are not detectable from basic diagnostic scans at the dealership and Toyota or Lexus will likely not go out of their way to search for a tune if a vehicle is brought in for minor warranty repairs. However, it is theoretically possible to perform a checksum of the ECU and verify that the calibration does not match, and while this possibility exists, we have never heard of this occurring. With that said, if your vehicle is in need of warranty repairs and you have concerns, contact us and we can return your vehicle to the stock calibration prior to bringing it in for service. Once the repair work is complete schedule an appointment with us and we can reflash the tune back onto your vehicle at no charge.
  • Will my vehicle pass emissions testing after it is tuned?
    Our tunes are designed to NOT circumvent any emissions standards, and all emissions related features on your vehicle will 100% remain intact after tuning. The tunes themselves are designed to “blow clean” and remain inside all levels and thresholds allowed by federal and state emissions standards at all times. As long as you have not modified your vehicle in a way to circumvent the emission requirements set forth by your state or local laws then yes, your vehicle should pass emissions testing while it is tuned. With that said, if your vehicle needs to be smogged and you have concerns, contact us and we can return your vehicle to the stock calibration prior to testing. Once the test is complete, schedule an appointment with us and we can reflash the tune back onto your vehicle at no charge.
