    A little of this and a little of that. Its pretty run of the mill.
    @OVTune I got a link to the logger from a friend and got it working with my laptop. Does that mean, I can start sending logs now? Thanks.

    Now that there is a new logger out (Im still using the old one, one of the lucky ones that it worked for). OV, are you only going to be accepting logs from the new logger app version?

    2nd Question: should we be data logging only when you (OV) request us to data log? Or do we data log anytime we receive a revised tune file or experience abnormalities when driving?

    Thanks!

    I have a question. I am waiting on a base tune, but once I get it, does base tune have Gear Lock, and is it safe to tow a travel trailer with the base tune without revisions? Once I get the base and some logging how long does it typically take to get revisions done? Working on scheduling another camping trip and want to do it sooner than later with the weather getting colder by the day!

    Check out the first post in this thread. I'm very happy with the tune. I'm unhappy that I owned my truck 6 years without it.

    @mikmikcm15 my average before tuning was 12.5~12.7mpg in S4 mode, all city driving. I now average 13.3 as of today, Oct 9. Hope it keeps climbing as the tune adjust.

    I think the exact number isn't as important as the fact that there was an increase. I posted actual calculated numbers a while back of a one way, non stop, tank of gas I used on the highway. 70-75 mph the whole way and was calculated at 16mpg. There's no way that would have happened before at those speeds, especially with 35 inch tires.

    That being said, I doubt I'll ever find out what city mpg will be. I have way too much fun driving. The only time I care about my mpg is on trips anyway.

    Im a solid 14-15 mpg in my truck with factory size tires. I definitely get some drag off the habitat though down the interstate. I found out in Colorado idle is not nearly as friendly as the Tacoma, its quite thirsty on the trail.

    Thank you for the update! I am convinced with it, upon reading the whole thread it seems like this tune has more to offer than dap. I cant wait for them to open again and the tune to be completely developed.

    Flex Fuel Patch Notes -
    Patch - EROM- v1.04
    Release : ~ expected December 2019

    it has taken us quite a while to make some further enhancements for flex fuel trucks based on ethanol content, so that we can create a tune that will adjust power based on ethanol content. Here is our current patch setup for the Flex Fuel Tundra that will make on the fly adjustments to fuel based on 3 determining factors > Engine Speed > Engine Load > Ethanol content.
    Our next piece of this patch will be on the fly ignition enhancements based on these 3 variables as well.


    Some testing and further tweaking will be done on this patch this weekend on our truck.


    Flex Fuel Enhanced fuel control.
    Direct Target AFR by calculated ethanol content.

    Tundra EROM Flex Patch.jpg


    Load Based Fuel - adder for Supercharged Flex Fuel Trucks.
    Takes our primary target and averages based on Target > engine speed > Engine Load > Flex content.
    Primary target + Load compensator adder / average of = target AFR


    Flex EROM Load patch.jpg








    for current / pending tickets waiting on an update, we will have a lot of updates out tonight through tomorrow night. We have *almost* every ECU supported now.
