VF Tuner ECU/TCU Tuning for the GX550 (5 Viewers)

@VF Tuner - I'm getting an error reading my VIN. I have the latest firmware and software.

I also noticed that the ECU harness have exposed wires. The connector is not sealed all the way because of the wires. Is it only two wires connected to all pins?

I had trouble as well but was told it wasn’t necessary if the VF tuner software was up to date

@VF Tuner Sorry to keep pestering, but still no tracking update. Could you please check? Order # 20037
I apologize I ended up getting super sick friday so couldn't go back to this. I am just waiting on my logistics guy James to get this out.
Going forward I plan to have everything prepared > shipped > etc directly from my main location here in Korea, by the end of this month.

I tried this and it will get to the opening com3, but it gives me an error that it can’t connect to the primary bootloader and then pops up a window to make sure the wiflash adapter is connected.

The firmware currently is esp 1.2.2/stm 1.2 with the program saying its attempting to update to 1.8.2

Are you on windows 11 perhaps?
this issue can still happen on windows 11. We are working on that solution.
