Can anyone tell me how to change the "kph" to "mph" on my Axiom 8w computer? I've tried holding down the left blue button for 5 seconds in the "distance" mode, but no luck.

You might try contacting Performancebike.com. I think they are the only place that sells Axiom computers. I've got several of them, including an older one like yours, but unfortunately have lost the owner's manual for the older ones. If you still have the receipt, Performance may let you exchange it for a newer computer. They have very generous return policies. They gave me $25 credit on a very old computer -- although I did still have the receipt.
