Also an update, my ECU has been unlocked and reinstalled into my LC. I have an appointment to get a stock baseline dyno + tuning dyno on 5/12 and I’ll post results shortly. I may end up not going with an E85 tune and just go with a 91 octane tune from TunedByLoi.

Who’s doing transmission tuning for the 10 speed in the LC?

Hey all,
We attempted flashing a couple months ago but it didn’t work. I’ve been in touch with OV Tune to figure out why it didn’t flash. They’ve ordered their own LC 500 ecu for testing and I’m just waiting on any updates. No updates from them so far, hoping we’ll get some soon. Loi has my tune files ready so we just have to wait for OV Tune to properly unlock the ecu.

Nice to see it finally cracked. Aside from the engine fuelling/timing stuff, is the gearbox programming accessible? Can we adjust shift times, shift logic, engine brake control, any of that stuff?

Is there any way to add a few more burbles and pops to the exhaust w/ this tune?

- actual benefits (besides subjective butt-o-meter)
- how it was cracked as i believe toyota/lexus ecu's have never been cracked before as far as i know - could be wrong though (maybe encryption?)
- what it actually changes
- possible normal driving downsides
- what the long term reliability impact is
hopefully all positive as we learn more.

I don't know what the method to crack the ECU was, but we got halfway there a few months ago, but weren't able to flash; then just yesterday with the new updated VF Tuner software I was able to flash the file Loi provided me. If you want details on how it was cracked you can reach out to Support@ovtune.zendesk.com.
For details on the tune file you can reach out to Loi (email above).
Loi's tunes are very reliable, from all of the previous tunes he's done I think all of his customers have been fairly satisfied. I definitely have been - my RC F was also tuned by him.

Curious as I follow your progress with the tune, do you have headers or an exhaust on your car? It doesn't show if you have any mods other than the tune.
Thx
