VF Tuner ECU/TCU Tuning for the GX550 (2 Viewers)

This is actually GOOD!.
Once someone gets this TSB done, if they can read their ECU, we can make updated tunes for it and we can update everyone who wants to this TSB version calibration and they won't even have to go to the dealership.

I hope this works…. Why did Tacoma tune fix the shifting issue compared to the GX? @VF Tuner

When the tacoma tune was developed it was specifically to fix the horrendous transmission issues.
When the tune for the GX was first developed we were not aware of such specific transmission problems. Also most customers who have our kits have not mentioned to us they have shifting issues.

I'm quite confident it will work, and we will disassemble this new tune and see exactly what Toyota did to the transmission tune and explain it publicly.

it's 100% going to happen as soon as we get the file. We do this on many toyota ECUs when toyota releases an update.

@VF Tuner do we need to revert back to a stock tune when getting this TCM update or can we stay tuned when getting this?

You can stay tuned.

I ordered and paid for my tune and got a shipping notification on 9/3. The package has still not been shipped; USPS shows the label was created but the package not shipped. Arrrg.

I submitted a support request but have not heard back.
