2007 FJ Engine diag.
Trying to flash programming for the engine diag system in a 07 FJ. It seems to write okay but doesn't save any changes. What am I doing wrong?
Thank you,

If you're flashing the truck with a modified calibration, and then performing a read (to confirm it wrote), you're not going to see the changes in the read since it's a virtual read and you're supplied a virgin copy of the calibration for your OS each time you read.
If the above doesn't fit your situation, can you elaborate further?

That is exactly what I was doing, Thank you.
