    Congrats on your new truck! I wonder why mine is 04B40... First batch? Pro?

    Thank you, sir.

    Dunno on the calibration IDs, but I doubt it's PRO related.
    It's more likely Toyota decided to update some things as the 19 M/Y progressed. Matt probably knows...

    Someone explain the difference in 04A70 and 04A71 to me. Can I flash, or have the dealer flash up to 04A71 if my ID is 04A70? Feel like I'm missing out on the beta by being a step behind

    I would have the dealer look at. Perhaps some type of TSB was issued or just some tweaks to the ECU between production. There is always the tech stream DIY method but that runs the risk of actually bricking your ECU if not done right.

    Hopefully those with greater knowledge can chime in.

    @OVTune I flashed the latest O4B13 dongle tune and was successful, but now my truck won't start, the engine just turns over.

    Make sure you selected the correct file and try reflashing. The revised files were posted two pages back this morning.

    Oh and not to be a stickler but if your truck won't start it wasn't successful..rpyqxrxKyMXHnavCpZzV.gif

    Also try flashing back to the tune you were on previously.

    Did you turn the ignition off after flashing?

    I tried flashing back to the tune I was on, back to stock and even tried to read the ecu. They all came back unsuccessfully.

    Yes, but when I went to turn it on to idle it wouldn’t start. It will just continually turn over.

    Clear DTC, turn off ignition, turn on ignition for 30s, turn off, start truck (if it will start) , turn off, try to flash again.
