Does anybody ever worry about how many times we can reflash that PCM by changing from one tune to another with our programmers. I swear I've re-tuned mine 20-25 times already. Problem is, it takes alot of trial and error to realize exactly how you want every setting. I found I even had to tweek it a bit after Bill's custom work. I have tried to give proper drive cycles in between though. But just worried about the PCM's durability I guess.....I don't have a tremendous amount of faith in computers.
I do seem to have it nicely dialed in now though

 

I have flashed my PCM 100+ times.

 

I don't think there is a limit or if there is no one has ever reached it.

 

modern flash NV memory is good for way more re-flashes than you should have to worry about. There selling flash disk drives to replace hard disk drives. Good for > 100K writes.
