I was not doing write entire back in November with my version. Have not wrote anything for a while as I am running a canned tune right now.Blades, this is my write calibration story so far:
I did a few tunes today, did a write entire first time, no problems. Then I did some driving and changed a few things and did a write calibration...it gave me a communications failed error after the erase and before starting the write. I did a write entire right after that with no problems.
Does that sound something like your experiences?
