    When you purchase our tune, you are not getting only the 87 FOB tune. So it's $699 for flashing cable + software + 87 / 91 / 93 base / 87 / 91 / 93 FOB + free updates.
    Currently, there are not gains on the 87 tune until we release the new ACIS mapping (free) which will then provide more torque via mid-range, regardless of octane.
    If you choose to only use 87 FOB and nothing else, this is your decision. Just like any other tuning option on the market for X Y Z car. "stage 1" map "stage 2" map etc. If someone buys a cobb accessport for their wrx and only uses stage 1 tune which adds 15 hp, and not the stage 2 that adds 50.. should they get it cheaper? No, because you are provided both.

    What is a torque tune? There is no such thing. When a tuner develops a map, the goal is to find as much torque as possible safely everywhere, and that is what we have been doing.
    Now different files have different responses at different RPM, but this isn't from "unlocking" or "locking" torque.. but by changing how the throttle responds to demand.

    A torque tune or towing tune would be a tune focused on power made lower in the power band not up to oh lets say a 6900rpm redline.

    and Snickers?

    And thanks for the responses you only seem half triggered. I am helping you with your business you know this ..you mentioned it a bit above.

    I honestly don't know what to say regarding snickers.

    It's not possible to just create more torque past MBT or knock limitation. That is why we investigated ACIS tuning. You want more torque you need > exhaust > more octane > cams > porting > etc. Just like any other engine.



    how does this comment help us ? "Several years have passed and no final tune version with minor updates like other platforms".. How many years exactly has our tune been out?

    If you think its too expensive than DO NOT BUY IT!! It's an aftermarket tune that is absolutely NOT required but IMO makes this engine A LOT more responsive and drivable. FREE MARKET Snickers!

    DO some homework before making a false statement and don't expect some backlash from a community that respects what Matt and OVTune has provided thus far

    Torque tune? There is no "magic" tune to unleash low end torque in this relatively small displacement engine HENCE the turbo kit project. A small diesel engine would have provided lots of low end torque with good MPG's but the 3.5L 2GR-FKS is what Toyota gave us.

    I believe Mat has been VERY transparent with his product & website (dyno runs, very active on TW, responding to emails). His ongoing tuning updates is a GOOD thing and shows desire to provide a quality product to meet everyone's needs

    Furthermore, the lack of a competing tuning software within a huge market like the tacoma proves that it is not an easy product to develop & bring to market. I think many of us would welcome competing tuning software products but there are none! Until then, OVTune puts out a great product at a reasonable price (I have zero issues since the tune has been installed in the truck since last September & would buy again without hesitation).

    Not much, yet.
    :popcorn:

    Soo I knew what I was buying when I test drove the truck. Power and response we're far from ideal. But I dealt with it cause I wanted the Tacoma.

    Then I stumbled onto OVtune. It made things so much better. It's nowhere close to driving a 5.7 Tundra, but it's better than stock. I don't get why people get upset when Mat can't magically fix every gripe we have about our trucks. Is test driving not a thing anymore?

    Yes.. They were developed on a dyno, with exception to FOB which was just requested by users, and is in a load range that isn't full throttle anyway.

    On top of that almost all engine related parts and translated right from AT to MT.

    You have a 3500rpm capable converter attached to a manual transmission?

    Sentence structure,phrasing and perception. Your comments kinda run together clouding the subject. Those not savy with auto lingo/tech might get a bit confused ;)

    I'm probably alone in this opinion, but street testing our M/T tunes (with YOUR arse in the seat :)) at this point in the development is way more important than dyno pulls. The power is there (except for a midrange dead spot in 91 FOB), but there are still some driveability issues.... and yes, my truck stutters so I'm not speaking of that. Inconsistent throttle response when trying to rev match is still there. Rev hang is still there.

    I think some seat time doing some data logging would give Mat a much better perspective on where improvement can or needs to be made.

    Nope, just trying to see why you think a tune can’t be leveraged by a driver aware of what the engine is doing. Clutches wear out sure, so what? Every part will eventually. Heck, you’ve probably spent more on tires for a drag race than I’ll ever spend rebuilding this transmission.

    I’m here trying to learn, I’m not as good with vehicles and wrenches as I’d like but I think I know enough to be dangerous. If you think I’m sofa king we Todd it that’s fine by me but doesn’t really help anybody or the thread. I’m new here so just getting a feel for it but I had heard it was a little more friendly/helpful than you demonstrate.

    Uh... this isn't the dev thread guys.

    I don't wanna take hot showers with any of you, but I try to be friendly when possible.

    Inconsistent throttle has already been figured out and a patch is under way for that.
    Rev hang patch is also being worked on. Seat time in a MT would be lovely and something we definitely need, but before that point we really want to wrap up all of our 2.0 code, throw it in the truck, and then finely tune it. Just like the AT folks, I don't want to try to tune around the stock ECUs limitations, so I'm writing in my own stuff.

    I Think I may know what you are seeing / feeling at low throttle control. Give me a moment I'll show you a few tables that could be the culprit

    So, putting aside the multiple 3D tables that create the "demand" requested.. (these are stock tables)

    here is your base throttle scaling. (basically X volt = Y angle)
    It's not a smooth scale at all.
    scale.jpg

    Then, you have independent gear throttle limit tables (angle to accel angle)
    limit.jpg



    These tables are referenced then modified by multiple 3D tables at the same time, but the "base" (scale, cal) isn't really "great" on it's own.

    Gawd. Is it me, or does that seem dumb?

    What would life be like if the first graph was linear other than the first couple points and the second just identical for all gears and neutral?

    I suppose that I just dream of old multiport EFIs. Or, the simple throttle cam profile on my bike.
