Overland Torque Tune (OTT) by Overland Tailor

The 5G 4Runner TCU calibration isn't horrible (like the 3G 3.5L Tacoma). We still do a good number of 5G 4Runners without access to the TCU calibration, it's still a pretty significant improvement over the OE calibration.

It's potentially our next platform. We have 5.7L Tundra/Sequoia/Land Cruiser/LX570 in the process at the moment.

 

Does the TCU adjust itself to the recalibrated ECU?

 

There are adaptive trims within the TCU related to the transmission, yes. But all of the "core" parameters and functions are fixed within the calibration. Things like shift points, torque converter lock-up/release points, line pressure, torque management, etc. all remain the same as the OEM calibration.

 

OTT making the 4runner fun again... And Magnuson. Big thank you to Drake at Adventure Motors, but one should be careful going there as the mod bug bites hard just pulling in the parking lot. So many nice trucks and walking in the door slaps one in the face with mods; rims, tires, lights, big brake kits, custom fabrication and the skills and knowledge to answer questions about them all! Joking aside, if your ever in the KC area, look them up.

 

Be sure to post improvements, better yet, burnout and donut videos. And maybe a few 0-60 launches.

 

Lol, no.
