My cluster is cracked and was going to get another one but need to know if i should worry about mileage or if its stored in the ecu?

 

It's not stored on the ecu, it's stored on the cluster. What cracked on the cluster? If it was just the see through plastic cover, it's replaceable.

If you’re really set on replacing it, try to grab 05+ with the new design. I’m almost sure it’s a direct swap.

 

/\ Everything g35lopez said is correct we have to order ours with the milege etc already put on when we do warranty work.
