Hi I was just wondering if this was a normal problem. My edge doent seem to correct the tire size at all. No matter what I do. I adjusted way up and then way down and it doesnt do anything. Any help would be nice thanks

if you are referring to the factory speedo, it won't.

that is to change mph display on attitude.

thats bs. How come it wont change the factory speedo. My older 01 had a predator and it changed. Is that because the edge is a reflash type sytem where the predator is not.

The predator is the reflash type and the Edge is an inline harness box used to alter the ECM's signals going to the various engine components. The predator can adjust the speedo since it tells the ECM what the tire size is. The reason the E/J isn't able to do this is because it doesn't know the E/J is even there.

Yep, what lakingslayer said... if you want to see your speed w/ edge, bring it up on the attitude.
