This is the YotaWerx ECU Tune for 2024+ 250-series Land Cruiser (LC250).
YotaWerx brings a unique blend of more than 40 years of Toyota Master Technician and Professional Performance Shop expertise to the Toyota/Lexus world, developing the very best in aftermarket ECU and shift point tuning. YotaWerx continues to be proven the best performing ECU tune available for 2003 and newer applications and we are excited to be their only CenCal tuner!
Designed to enhance low-end power, eliminate mid-range flatness, provide a consistent and predictable throttle response, significantly improved shift logic with smoother shifting and greatly reduced gear hunting, smoother power delivery through the full RPM range, and the elimination of low RPM dead pedal feel.
After completing check-out, we will call to schedule your tuning appointment. Theย tune is custom-made to your exact vehicle configuration and requires a few days to be compiled by YotaWerx. Tuning is performed at our shop here in Central California (click for Google Map) and can be completed before you head up to one of our dozen local 4WD trails or even on your way to Disneyland with the family!
This is an affordable one-time upgrade that takes your ride to the next level with improved performance and drivability without sacrificing engine safety or reliability. Before you invest in a lift, new wheels & tires, or heavy bumpers, make tuning your FIRST PRIORITY!
