    PITA, I suppose that after a few you get into a rhythm though, like doing the Cam Tower Leak repair.

    @OVTune
    You've asked me to send you my logs, but you reply that you haven't been getting the attachments on your end. I've tried again via offered alternate email address, (even sent log via DM attachment last week) but don't know if that has worked. I didn't want to bugger the Zendesk queue (#4706), so I thought I'd query here as I haven't heard if either of those attempts were successful. Thank you!

    @OVTune Order#5221 I am in same boat resent logs for the 3rd time to your gmail and zendesk this time as you requested. Sick of burning fuel on this base tune and no torque convertor lockup with gearlock. Got 9.5 MPG yesterday towing 2500 lb low drag trailer. Prior stock was 10.5-12.5 depending on wind, season, temps, etc... Still waiting for an email reply on what my base tune includes feature wise. Maybe torque convertor lock up with gl doesnt work on base tune. Be nice to know!

    @OVTune I'm seeing improvement in MPGs this week with just base tune. 13mpg average today, before was always 10mpg no matter how I drove.
    I'll do some logging this weekend for first round of optimization

    Probably because you had prior rich bully dog tune for your S/C? Stock I have bad milage on base, and seams others have reported similar for base tune. Glad to hear you have the tune and its working well for you!

    Both the BD tune and the Toyota TRD SC tune yielded similar shitty gas mileage.

    As far as power, I don't feel any difference and I'm not sure if I have gearlock in S mode and when I press tow haul, I have no idea if this is a different map but I do notice a difference in transmission downshifting sooner with tow haul on vs off.

    Be really nice if in every tune sent there is a list of what features our tune has. For the info and for safety I don’t understand why it’s not included. I am still in the dark with no info on what my base tune has what buttons do what etc!!! Using gearlock for the first time almost resulted in a crash for me... had no power getting into traffic after a slow acceleration was in d stuck in 6th gear and assumed it only worked in s mode!!!

    5325 too. I resent my log yesterday. (7mb seems like a pretty low limit) My file was a 12 or so minute drive 11 miles from home to work.

    How far/long should the log be?

    From memory. Idle a couple of minutes, 2 full pulls and then some casual driving. Break up into 3 files. That should do it.

    My base tune is rich, lost mpg compared to stock, Seem power is lost at top end also but, better throttle response, more Lively and enjoyable to drive in low and mid range. Gearlock only tow/haul mode and very useful on highway cruising.

    If any of you have gear lock coming unlocked or not locking the torque converter, like my truck is doing, Mat did reply to me saying that it would be addressed when direct shift and gearlock being tied to s mode is available for my ECU. So it sounds to me its something he knows is an issue. Just thought I'd throw that out there.

    He just said Zendesk restricted sub 7mb files & mine was 7, gave me a different email address to send it to.

    Maybe... I've had several revisions and each time I send a start up, a few minutes driving around normally, one hard pull in 4th and a wot from a stop.
    He seems to be able to get what he needs from these.

    Hmmm, I haven't paid attention to what size mine are, but when I do a log I start and stop on each specific category of driving. I don't hit record and leave it recording through each driving task.

    I didn't see any instructions so figured an 11 mile drive with red lights & a few patches of open stretches of WOT would be good.

    I'll do it differently next time if asked to.

    I swear that he told me 10MB was the max.

    I made one that was kinda long because I find it difficult to try to find somewhere safe to pull over to start/stop the logging. I guess I don't multitask very well. :tinfoilhat:

    Better a big file than getting into an accident stopping the recording.

    Ya, that'd be embarrassing....

    And FWIW, Mat must be getting the data he's looking for because he isn't suggesting that we log differently; and as far as I can tell, most of us are pretty happy with how our rides are running.

    No, I understand. There really wasn't any. That was just what I had been doing.

    You mean those twisty little mountain passes aren't safe...? :devil:

    I had no idea there was a max.

    *Insert standard reply suggesting that it's not me nor the terrain that are the issues, it's all the other fools that we're sharing the road with.* I have no problem taking my half of the road out of the middle, but should another do it! ;)

    Mine locks and unlocks on 5th and 6th. On their video demonstrating Gear Lock, there's an option to have your converter locked.

    I just emailed my first logs today. Not sure of the turnaround time.

    I did 4 files. Cold start and idle for like 3-4 minutes. Few Mile drive to Lowe's, normal driving. 2 files with a couple WOT pulls in 3rd S mode to redline. Hopefully provides some meaningful data for rev 2.0 when Mat gets to it. Very excited to see what if any difference it'll make.
