After waiting 6 weeks for the parts dept. to get my new ECU I called them. After a few games of putting me on hold the service manager said that the orders for the updated ECU's were very backed up, then they canceled all of the current orders because a new update is coming and it has a different part number. So he reordered the new ECU update and they should be getting it by the end of the week. So if you are waiting for your Trac ECU you may want to double check with your service manager and make sure they have reordered the new update because they are not going to get the original order.
