    It's odd as I only got 1 going home on Monday, but then it was 85f and got up to temp quickly.

    What cylinder, What temp, etc etc
    This does absolutely nothing to help see the situation and only helps to cause more forum discourse. Here we go again. Always the same person too. Sigh..

    I'm starting to think that trucks that get high misfire rates... since it's not a universal problem.. is related to a hardware component on that truck. Just like the stuttering issue on some trucks in 5th and 6th.

    Someone in here, don't know who, has a brand new 2019 and it does it right off the lot. The said they've fought with toyota forever about it.

    I have verified multiple times that our test truck gets no out of the ordinary 2-3 misfires per driving cycle. Tested multiple times in different temps, including extreme cold.

    @OVTune I have noticed on 93 base a momentary deceleration at each shift under 50 mph. It takes place during the actual shift and is enough to feel in the upper body. It feels just like letting the clutch out on a standard with engine rpm too low. 110 miles on 93 base and this sensation has been consistent.

    It makes no difference if constant peddle or accelerating

    I can't solve anything reading random forum posts.
    I need your ECU ID, octane you flashed, mods, etc.

    'Always the same person'

    You've got tickets from me, I'm yet to hear anything from you. I get why you don't want this on the forum, it looks bad for the tune.

    28 misfires for a 6 mile trip, across all cylinders (between 3 and 6 mostly). Temp was cold start in 74f weather. Didn't go above 50mph during the trip due to start stop traffic, didn't go over 2500rpm.

    Just because only certain users are actually logging for misfires... does not mean it isn't universal. Stop blaming the hardware and 'it does it stock', 'It's a Toyota thing'.

    Actually it is mostly you, and it's a repeat thing.
    You have our logger with Flash Manager, you have always been over critical, which you even admit multiple times. I think at this point you just like to bring attention around. There has been times it seems you go out of your own way to find something you don't like just to post here. As if it's in any way helpful.

    If it does it stock it's not a stock issue?

    If your truck has continual issues, I dont think the tune is going to work for you. Flash the truck back to stock, return it I'll happily refund you. I give up.


    There are multiple people who do log misfires and get nothing out of the ordinary. Then there are some trucks that get high amounts at random times.

    So couldn't he just send the TSB tune out with the other tunes that way everyone is on the same starting point ?

    There are enough people that can barley turn on a computer so having people flash the TSB themselves probably isn't the greatest idea lol

    I would not want to provide anyone with someone else's updates and say here, load this. If it failed or causes and issue applying that other vendors update (Toyota in this case) then who is liable for a bad update? Who supports that other update? No, just get the TSB from the dealer if you can justify it or don't and wait patiently as we all do from time to time so Mat and bring the updates across the mess to Toyota versions.

    I wouldn't sell my OVTune for twice the price I paid.
    Wait, yes I would, then I would buy two and install them both for double powa!
    Oh if only it worked like that....

    - Regarding misfires.
    I Have made changes to valve timing and ignition timing and have verified, with included log data images on post 1, that our test truck does not receive, under any conditions, any out of the ordinary amount of misfires in a driving cycle cold or hot.

    If your truck, for any reason while tuned, does see an excessive number of misfires, please let us know by zendesk the following information:
    - Model year of truck
    - if you had your crank sensor replaced (if your truck had that TSB)
    - ECU ID
    - Octane of tune
    - when it happened and under what conditions.

    I cannot solve it for trucks who still have the issue by playing post tag on tacomaworld.

    For those with OBD fusion, what OBD connector would you recommend? I was looking at the Carista LE

    I too was seeing an increase in misfires on the original 1.05. I flashed back to stock, but just loaded the new base 1.05 last night. I went for a very quick drive (5 miles) on an already warm engine and got 3 misfires. I hope this base file is the fix. Just out of curiosity, have you already replaced your crank position sensor?

    I use an OBDLink MX+ for my motorcycle and for vehicles at work (chevy so I wanted one that could read SW-Canbus). OBDLink is also the creators of OBD Fusion so....

    I wouldn't use it for OVTune data logging though as Matt provides his data logger with the flash manager.
