VFTuner Support for 3.4L

Looks like VFTuner may be supporting tuning in the 3.4L trucks now.

They have this special connector for the 3.4L PCM

And they have a basic tuning guide.

I have the old VFTuner flashing device and I cannot pull up the tunes in my software, so it looks like maybe you need the newer WiFlash and version 2.0 of the software.

 

Waiting for HPTuners support -

 

That would be nice. HPT is so much better to use. I tuned my own F150 with HPTuner for years and using VFTuner is terrible in comparison.

Unfortunately it is the only option for all GX460's and only option for my 2016+ Land Cruisers/LX570's, which are they two Toyota's ive owned Its annoying because HPT supports up to the 2021 Tundra, so its probably pretty doable to support the 2016+ LC
