Thanks for the reply I've tested one of your routing.xml (mycar12), sometimes it works sometimes not. The problem is your mycar12.xml is a car profile, and I didn't use a car, I use a motorcycle. How can I change my own motorcycle profile Heuristic Coefficient? Or maybe you can help change the HC from this file?
