Overland Torque Tune (OTT) by Overland Tailor

Ask for the 9.2 update, and you can try the settings to see what's best for you. Asking for the 9.2 update is the key.

 

Any new updates for The 2nd gen?

 

+1.. 2nd gens in the house, can we get a shout-out

 

I use to have that "lunging/lurch" when I first tried OTT back in May/2022...I believe it was version 7...Mild/Medium Tune Setting.

My tuner heard my plea and put in a lighter setting...lite/mild.

Next up was the major update OTT, version 8 with same settings in Jun/2022...lite/mild.

By the time the next version came around, I was adjusted to custom Mild-Med Drive/Spicy ECT with Gear Lock in Oct/2023.

I use the recommended octane and have no issues with jumpy throttle in parking lots.

Looking forward to meeting up with my Tuner and getting version 9.2!

 

You never know what might be coming.

But truthfully, I'm not sure the calibration could be improved much. If it's a different setting, we have 18 possible combinations for 2G 4.0L calibrations. Currently, there are six different throttle profiles and three different transmission tunes. And there's always our custom tune option for a truly custom file.

 

I went with Lite/Mild from the beginning, I have a hunch that changing yours to that may help. When I got the tune, I told Alan that I had concerns regarding snow driving; that's what he recommended as the different levels of tune don't really affect HP/torque, they only affect throttle response. Folks are more than welcome to correct me if I'm wrong, but that's my recollection.

Even with Lite/Mild I do get a tiny bit of a lurch when the engine's cold, but it goes away once the engine warms up.

All of that said, I'll still probably do the update anyway the next time he's in town.

 

Been following OTT for a while now and I am ready to be on board. Who do I contact to do the tune? I'm in Sacramento, CA.
