Using other bins

[87gmc]

Is it safe to just program other bins from the same year and model of car into another pcm?

Yes, no problem, Flashscan won't let you flash in the wrong calibration from a different year / operating system. So if it doesn't match, it will tell you anyway.

I was wondering because I have always heard not to do it in 98/97.

Didnt know if it was the same for 99-up
