No, but it's been an identified problem that none of the really smart guys in the field were ever able to figure out or workaround. I think Moates and Mansur both dealt with it and never did work it out. If it was easy, it would have been found out. I've swapped ECM's with a GM service replacement with different PN, did the same thing. The solution was to go to MAP apparently. Not overly worried about it, not like I need to tune all the time, but just never know when it's going to strike, so on the rare occasion I'm tuning, and it happens, it's irritating.
