OV Tune issue/error

Error beow, Unable to communicate with ECM


Prepare ECM process works.


Strong Internet connection, over 12v, everything shut off in truck that doesn't need to be on...I am at a loss whcih isn't saying much regarding my knowledge when it comes to me and tuning.
Trying to load a ToyotaWerx tune. @mZiggy is stumped too. I completely unloaded and reloaded VF and drivers. Why is the program not talking to the ECM? Any ideas would be great! This is typically where I grab a BFH (Big F-ing Hammer) and a torch and get to work but, I hear thats not good for computers. @drizzoh any thoughts?

 

Solved. Vehicle ECU ID is 04B30; requires update to 04B33 via Toyota Techstream.

 

I'll run it to the stealership...not going to risk f-ing up that flash lol

 

Update.
Ran to the stealership and had them flash me to the 04B33, $120 well spent IMO. The YotaWerx, Blackhawk flash went super smooth after that.
I have to say, first impressions are awesome! Shifting is on point, MPG went up in the 30 miles of mixed test driving and the overall throttle response is night and day better. Not to mention that the gear lock is going to be a game changer off road. @mZiggy was a huge help while I fumbled through hardware, software and update processes too. My only complaint...I didn't do this years ago!
