2006 LX470 CPU upgrade (1 Viewer)

[pheery]

I have a 2006 LX470. CPU has an issue and isn't communicating with 3 of the 4 oxygen sensors. So i am looking at all the dash lights on. Recommendation is a new CPU. Before I do that, I wanted to see if there was a way to upgrade/flash my current CPU, add power and calibrate for larger tires, and fix the problem all at once? Being hopeful I am sure...

Is there anyone that does this?

Toyota's ECUs are known to be impenetrable. Even after Anonymous can hack the state department and super secure SSL, nobody has been known (or care much) to hack Toyota's code.

well damn. So only solution is to purchase a new CPU and have it programmed for my VIN?
