Can someone tell me the difference between part numbers 32109-08 and 32109-08A on the Screamin' Eagle SE Pro Super Tuner?

 

Good question, mines a 32108-08. My guess would be they fixed the failure to blink rapidly and stop recording when full problem. With mine if you record too long standalone it corrupts the data and you have to start over.

 

Well, actually, that's likely hoping for too much. It more likely just has the 1.005 update already applied which fixed the timestamps in the log files. A millisecond is 0.001s, but the original version used 0.01s as a millisecond.
