VF Tuner ECU/TCU Tuning for the GX550 (1 Viewer)

[tig]

Got the tune installed, finally.

Now, where do I find information that will help me understand how this tune is different than the original? What does the TCU tune do? How do differnt drive modes impact the tune.

I've searched the VF Tuner website and scanned this thread.

so for the people who purchased the VF tuner is it what you expected? Is it worth the price?

Thank you. I used the 91 + TCU tune.

Just did a quick test drive and the butt dyno says, "worth the money; a noticeable difference".

The transmission clunk is still there, but I didn't think you guys had absorbed the recent Lexus update yet. I'm really hoping you do as my dealer is 3+ hours away and I really do not want to have to drive all that way. Is it reasonable to expect you may be able to fix it once you see what Lexus changed in the TCU?

I've found that the VF tune really shines when you're cruising along steady at about 30-40 mph....you press the gas just a bit, then a bit more, and the acceleration really comes on like a strong punch.

any news on having the VF tuner configured

No, it is still on our active work list. Being unable to access australian tech docs directly has made this a challenge.

any news on having the VF tuner configured for Australian users? Have been waiting for months...........
