New CAMTuning hybrid update.
Some hybrid Tacoma and 4Runner owners have noticed a hard first 1–2 shift after the vehicle has been sitting — usually a jolt or thump on the first drive of the day that disappears afterward.
I’ve been working on this with several customers and have now isolated the cause and developed a targeted correction.
The result is a much smoother first 1–2 shift without changing the normal transmission behavior once the vehicle is underway.
I’m adding this update to all future hybrid calibrations.
Existing CAMTuning hybrid customers who experience the first-shift issue can reach out for a free update.
A big thanks to the customers who are willing to test changes and report back. That feedback is a huge part of how I continue improving these calibrations long after the initial development is complete.
