    Sure,

    1. I need to confirm, but some sequoias have tow haul mode and a ECT button, we wanted to confirm a few things because this gives us room for a few additional things unique to the sequoia as they both act independently on the shift and throttle.

    The combination (s mode, ECT, and Tow haul) needs to be appropriately handled in the ECU so that it doesn't hang up in the code. Basically.

    Not rushing but can you give me an idea when I might get my base (& verify you got my ECU info)?

    Order 5325.

    Thank you!

    Also, there will be a *slight* update with our S-mode control.

    S-mode control will have (optional) 3 things:
    1. Gear locking
    2. Full Throttle Direct Upshift shift control. (fully functional). -Allows direct and immediate shifting up or down at ANY RPM within the programmed allowable limits. (no you cannot downshift into first to get 1rst gear at 6000 rpm).
    there is no delay, you press it, it shifts immediately. You press it at "4877RPM it shifts at 4877RPM... you press it at 5155...etc..
    3. Full throttle Direct Downshift Control.

    My '15 Sequoia Ltd has S mode but scanning thru owners manual I do not see an option for both Tow and ECT. IMO ECT is very much like 'tow' mode, it modulates the shift points to higher RPMs to help with towing, hills, acceleration, yet perhaps it means something different here? Overall my interest in 'tuning' would be to improve fuel efficiency around town and normal highway, not necessarily to improve 0-60 or 1/4 mile times. So given that is that what the product is intended for? Thanks.

    :smash: Patiently wearing out my email refresh button while waiting for my tune revision to come in. In the mean time, found a smoking deal on some front and rear bumpers that Im hoping to have on by the 1st of the year. The look on the wifey face was not impressed when I told her I was buying myself bumpers for chirstmas. lol

    I found a set of used take off NFab bumpers locally that got taken off a truck before it got traded in. They have both been bedlined which is nice. Scored the pair for $500. :bananadance:

    A little of this and a little of that. Its pretty run of the mill.
    @OVTune I got to test your tune on dirt this weekend and the throttle limits worked great in soft sand. One request would be to increase the throttle limits in reverse as an option. When we get stuck in soft sand, sometimes, we need to get going in reverse and it was still bogging down. Thank you sir!

    So I drove the truck from Miami to Fayetteville NC for Thanksgiving giving. The power is significantly more than before and the truck drives great. Additionally I was carrying a ton of stuff in the truck (air compressor, mig welder, and gas powered pressure washer) plus my normal stuff that I carry all the time (150-200 lbs) and got better fuel economy than ever before. I didn't do the speed limit, hit triple digits more than a few times, and cruised between 78-88 most of the time

    According to their Facebook page, they were able to flash a 2019 TRD PRO 3URFE with their custom EROM calibration. This is as of this morning.

    I wonder what kind of "extras" are planned for the additional space found in the 2018+ ECU's
