Thread Starter
2019:
Reprogrammed shift logic for 10-speed automatic transmission
- Range of Adaptive Variable Suspension expanded for enhanced ride comfort
- Enhanced steering, revised VGRS and change to aluminum steering support bracket
- Modified rear engine mounts
2020:
The LC 500’s 10-speed Direct-Shift automatic transmission received updated programming in 2019 to provide smoother shifts at part throttle while still offering more forceful gear changes at wider throttle openings. Updates were also made to the Adaptive Variable Suspension, including new bushings on the damper rods and a switch to independent rebound and compression orifices. Both changes allow for an expanded range of damping force for enhanced overall comfort. To improve steering feel, the assist levels have been altered along with stiffer steering box bushings, a more robust aluminum steering support mounting at the instrument panel and revised Variable Gear Ratio Steering (VGRS) tuning.
2021:

2021:
- Reduction of unsprung weight (approx. 22 lbs.)
- Suspension updates to provide smoother, softer suspension stroke
- Electronic absorber controls adjusted, bound stopper rigidity optimized
- Rear stabilizer rigidity increased to improve front turn-in ability
- Active Cornering Assist (ACA) added
- LC 500: Update to transmission timing, logic changes

I believe I read somewhere that one of the changes to the transmission involved the downshifting. On hard acceleration it would shift down to 2nd instead of only shifting down to 3rd. That's what I am interested in!

I would assume that not through Lexus. Maybe through an aftermarket tuner. Only problem is, cracking that ECU. Apparently there's been several tuners (RR Racing and Boost Logic) that've tried to crack the ECU in order to get a SC built for the LC. It's been quite difficult....

Concerning the differences between the 2018 threw 2021 coupes, although their were some hard parts changed out/replaced, it seems a fair amount of the changes were reprograming/tightening of perimeters..., couldn't a number of those differences be addressed by a good tuner or a Lexus dealer ?
