    @OVTune ?'s on the shift lock first post info .
    How does it work?
    To enable gear lock - Press "ECT" Button While in S mode
    Modifications made:
    While in S mode Gear lock can lock 1 - 6, (for safety reasons, the truck will automatically downshift at rpms under 1500)

    There is a safety limiter set in place if the truck is held at 100% throttle for an excessive amount of time.

    ECT "D" mode is now functional (shifting is still modified in ECT "D" but it is completely drive-able in ECT "D" now).

    S mode non ECT performs like stock S Mode
    D mode non ECT performs like stock D mode
    (in terms of shifting)


    I see that one shifts to S mode then presses ECT. the gear lock starts working .
    Once it is working in S mode with ECT on , what happens when shifting to D without touching the ECT button ? then shifting back to S mode again and such with or without touching the ECT button ? I hope you can see where I am thinking about the possible outcomes .
    One more ? , is the 6900 RPM mode for the AT also ?
    thanks .

    If you switch to "D" and ECT is still on, the truck will drive with ECT style upshifting normally. Technically even in D you can lock out downshifts, but it will still upshift and drive normally (and 5/6th D will still go down to 4th).

    6900 rpm AT is an option yes. I can even set 6900 in ECT Lock only, etc.


    Also regarding "legacy" shift, this is something I've worked on that can be used ONLY on base model 2wd trucks.

    still more to wonder about . such as activating gear lock in s-mode with ect , shifting to D mode , then back to S-mode , all without touching the ect button . When does deactivating /reactivating the ect. button come into play after the initial activation of gear lock ?

    Hey man - I took your advice a while ago and bought one of these computers for the eventual purchase of this tune . Happy to say that I just installed it after working for a solid year on my truck this was a great addition. The computer worked fine and the OV tune is amazing so far. Takes the bog out of the fuel pedal and moves the power back down the RPM range. Nice work on the tune Matt, I am day 2 with the 87 and really like it. Thank you for that, you have put in a ton of work and research dedicated to this truck and are an inspiration to all of us. Cheers yall

    Here is what I don’t get...1915 pages of comments. This forum wouldn’t even exist if Toyota would just do it right the first time. I hate the lag of takeoff in 1st, I hate having to downshift going up a hill at 7000 ft into second or even first. Do I really want to buy OV when it seems it has as many issues. We should even be dealing with this issue to begin with. PERIOD

    Glad it worked out for you. I'm not a fan of Lenovo consumer hardware, but their business laptops are top notch. I just got a brand new T480 for work and it's been great so far.

    Happy to hear that you are enjoying the tune. It sounds like it has accomplished for you exactly what most of us wanted it for in the first place!

    No, we shouldn't, but we all bought the truck and want a workable solution. That solution is this tune. The "issues" you see are called development and the immediate response by the developer (Mat) is normally unheard of. This is the first tune available for the Tacoma and was developed by Mat, with the help of all the fine folks right here. There are some minor "issues" with *SOME* trucks. Read the forums for a bit and you will get an idea of how picky these trucks are and how much variation in behavior there is from one truck to another.

    If you hate your truck that much and don't want to spend ~$800 on the tune, you are welcome to go trade it in.

    6900rpm in ECT only sounds like a great combo. Basically two tunes you can run simultaneously

    When we first entered the market, we weren't doing it to try to solve the numerous bugs and inconsistencies in the stock ecus code. We were working on tuning the camry when someone asked us to see if we can make more power out of the tacoma. Over time it evolved from a tune of making power to a tune dedicated to making this truck as best as possible. Fixing the transmission, fixing the limitations in the stock ecu that does not let you go full throttle, issues with misfires, stuttering, etc.

    The overzealous complexity of the stock logic, paired with the absolute maddening levels of assembly level inconsistencies and redundancy in the ecu means that if we did our remain a tune setup to make more power we'd leave 90 percent of the potential untouched.

    Luckily, the way the ecu calculates stuff in the line by line instructions (move byte, jump and register, nop, cmp...) allows us to exploit anything we wish. Only issue with that is testing takes time.
    The further we dig, the more we can do.

    Out of curiosity, are you looking at basic assembly code with these ECUs?
