    Updated 5/9/21
    FIRST, HAPPY MOTHERS DAY TO ALL MOTHERS.


    With more than 3 years of working on patches, code, assembly, and understanding of the stock ECU, we are about to release one of the BIGGEST and GRANDEST updates to this platform we have ever conceived of.

    This update uses our new platform, VF TUNER.
    This update will be covered in detail via a full PDF document that explains each mode and how it works.


    VF Tuner 2.0 Ultimate Map switch tune information.

    Full EROM, FULL Map switching with 8 modes. The most map switching modes ever!. When we say ULTIMATE we mean ULTIMATE.


    What is Map switching? It is ON THE FLY (no reflash) changing of the parameters of the tune, tables, maps.

    What maps are changed?
    Intake Valve Timing
    Closed Loop AFR Target (EROM code)
    Ignition Base Retard (ignition compensation switching)
    Throttle request to airload (throttle limiter)
    Shift tables



    A simplified (3 way) map switching flow routine of our code (designed exclusively for the toyota platform)
    9.jpg

    IMPORTANT: THESE PATCHES WILL ONLY BE AVAILABLE FOR THE LATEST ECU VERSIONS! YOU MUST BE FULLY UPDATED VIA TSB/RECALL/TECHSTREAM.



    full.jpg







    Parameters that initiate a MAP SWITCH
    ECT mode
    S Mode
    4 Low Mode

    MAP 1: STOCK TABLES
    MAP 2: ECT ON, S MODE ON, 4LOW ACTIVE
    MAP 3: ECT ON, S MODE ON, 4LOW INACTIVE
    MAP 4: ECT ON, 4LOW ON
    MAP 5: SMODE ON, 4LOW ACTIVE
    MAP 6: ECT MODE
    MAP 7: S MODE
    MAP 8: 4LOW

    ( Manual transmission release will be controlled via cruise control)






    8 way valve timing on the fly map switching depending on mode.
    Eliminate Atkinson mode.
    Create more aggressive cam profiles depending on mode.
    Create a MAX EFFECT ENGINE VAC MODE (4Low high RPM)
    Create a Tow based VVT for maximum torque at any throttle.
    - Lock the cam for efficienct dyno tuning
    and more

    VVT.jpg










    8 way AFR map switching
    tune AFR exactly as you need it in every mode.
    With our closed loop AFR patch, simply put the AFR you want, for each mode and DONE.

    AFR.jpg




    8 way Ignition retard base (tune your ignition timing trim depending on mode)
    Tune your ignition aggressively, or conservatively depending on what mode you use.
    Need a more conservative TOW + Gearlock?
    Set it to S mode + ECT ON. Ignition will trim to your desired settings
    - Create your own ignition trims for octane learning


    IGN.jpg










    8 way throttle control (control throttle limit and sensitivity depending on mode)
    Control throttle sensitivity EVERYWHERE, ANYWHERE
    -Throttle table settings for every possibly driving scenario on the planet.
    Need aggressive throttle in Gearlock? Set it to Smode + ECT
    Need to soften up that throttle but stay in gear lock? Turn ECT off
    Need to have throttle super soft? 4Low
    Need that same throttle to be super sensitive? 4low + Smode
    Need that throttle to be insane? 4Low + Smode + ECT!!!!

    ANY COMBINATION IMAGINEABLE


    Throttle.jpg













    8 WAY EXPANDED SHIFT TABLES FOR EVERY MODE!
    Shift control tables for EVERY MODE
    - S MODE GEARLOCK INCLUDED

    - literally tune the transmission. No guess work. NO what ifs. Set it and forget it.

    Not at this time. you can select from stock or our adjusted maps, each requires actually flashing the ECU with said map


    We have yet to see a tune be released with the level of torque management detail we have been working on.

    The complexity is the extreme level of torque management that Toyota implemented into this ECU. the only way to make more power is disregard all the "basics" and focus totally and completely on the torque control tables and calculation tables for "x" result to "y" torque target

    I assure you without a shadow of a doubt we can access your Tacomas ECU..
    I've already done the IS200T, RC200T, RC300/RC350 / ISx etc.
    I was just looking at the LC500 today, that's next on the list and uses the same torque management.

    The next step for us is to get a local Tacoma on the dyno to adjust the torque maps and show the resulting gains. We also have already selected someone on here who will be working with us through the remote tuning process and will explain with the forum the relative process / and how things progress.
    The torque control maps are *literally* identical in layer and nature to another platform that we have already done so I have very confident

    The ECU does not use the traditional means of tuning that we are all accustom to. where you get an ignition map, fuel target, throttle, and other simple stuff.

    Not at all. Rather the ECU uses...This is a little difficult to explain actually but I and some colleagues call it "5D" mapping, where the ECU will continuously alternate through 16 different tables in a "flip book" like fashion based on various sensor feedback and accelerator pedal to calculate a resulting "amount of power to create".

    That's just 1...1 part of a spider web of processes.

    This true, and increasingly common. Remember, when you press on the gas your not giving the engine gas, you are asking the ecu to let you go faster

    The only problem I see with this is that it could void the warranty.

    My Audi, I had to go to a dealer and get the APR tube removed prior to dealer maintenance. The dealer was required to scan every time. My service guy even told me to get it removed prior to coming in.

    Hopefully this can be done at home!

    Then why haven't you created a tune for the 2nd gen Tacomas?

    They came around to work on the most recent Toyota ECUs. Not a platform that started in 2005. Look at the list of models they have tunes for. Probably no demand for 2nd gen really.

    There is no reason why we cannot, we don't get asked about it very often.

    Want to see the inside of the 4.0 tacoma ECU? want to see the stock maps? they are ridiculously small.




    What do you mean by clear it?

    I believe they mean revert back to stock flash for dealer/warranty purposes.

    I'd assume this engine has more potential than the 1GR. Variable timing, direct injection, electronically controlled tranny.

    The tool we use mimics OEM TechStream Flashing, while correcting the checksum. Detecting the tune is impossible. Toyota does not even have a detection tool because they aren't even aware people are tuning them. In terms of older ECUs (sub 2016+ new logic) the ECU cannot even be READ by OBD, The dealership can see codes, freeze frame data, and calibration ID, literally nothing else. We have confirmed this with several master level techs AT dealerships. Toyotas way of "preventing tuning" has made it impossible for them to actually investigate tuning.

    I was at the dealership today speaking with the folks about remapping the LC500 and getting access inside the ECU and they are not even aware it's possible and actually encouraged us to develop this for the LC500.



    the 16+ tacoma ECU can be flashed as many, many times. You can flash your tune, back to stock, back to your tune, back to stock every time you go to the dealer if you wish to do so.

    That's what I figured. Toyotas aren't what people "tune". My Audi S5 on the other hand..... hehe

    Not that I would reflash this truck as my wife and I think it drives just fine (plus you have S-mode and ECT), and NA tunes yield very little gains on a smaller displacement motor, but it is very encouraging and great to see people tinkering with these ECUs and not giving up. I may want a bit more throttle control (less initial lag) but thats about it.

    This is all true. But keep in mind, toyota wrote this ECU for MPGs, not power.

    The GS350 has 280ft/lbs and 311hp.
    Our Tacoma has 265ft/lbs and 275hp

    This engine has some power that's all locked by the ECU.

    We are ready to get one on a dyno now. Basically an announcement that we have now disassembled enough of the ECU to find what we need to start our Alpha Tunes, and what they will consist of.

    Note that our tune kits will allow everyone to easily update from alpha to latest development, for free.

    I am quite confident that we will see very solid gains as this exact same torque management is used to create a "flat" torque curve at the expense of a LOT of torque on the low end.

    consider the engine makes 268HP and 248 ft lbs. A 3.5L with more accurate and precise camshaft control + higher compression and it makes less power than a 2GR FSE, a weaker engine that will put out over 280HP at the wheels.

    I don't know how "torque tables" work, but the GS350 2GR has higher redline, and is tuned for 91/93 (premium) octane from factory. They said not to think of this ECU/tune like a traditional tune so I dont know how they would have gains in that sense, but I'm not a EE.

    Edit: he posted above and said nice gains are possible.

    Red lines can be moved with a simple tune.

    I guarantee this tune will come with requirements for 91/93octane.

    We've revved the 2GR bottom end consistently to 7400.

    A potential drawback would be that for maximum gains / benefit 91 octane or better would be required.

    We don't have a set price point yet, but we expect it will be similar in price to our other toyota tune kits.
    once we get a car on the dyno and get out remote tools out to our our remote tester.

    Our kits will allow you to flash your vehicle from home, no need to remove the ECU.

    We may also consider a bench flash option if people want to send us their ECU for a lesser fee.

    Interested to see what kind of power and torque gains can be made, also to see the effect on fuel mileage.
    Also, I never understood why these tuners don't do what a SMARTY does for diesels.

    I have compiled it into 4 maps to help you visualize.
    the ECU uses all, and none individually, simultaneously.

    I believe we have asked in the past, and quite a few people messaged us about it...if you are in SoCal (we are in San marcos near Oceanside) and would like a free tune in trade for dyno results on our Alpha Flash, please let us know via email
    (use our website contact form www.ovtuned.com)

    Yup, graphs look good to me.
    Will You be able to tune the shift points? Kinda like the shift sence... but built into ECU.

    This is the only option I would ever consider. I know the stock tune from Toyota is all EPA bullshit. I would love to have all the power available. Waiting (impatiently) for dyno results.
