I just got my hondata p-28 with s-200b.
I started the car fine but it has a small injector base map so it's just dumping fuel.
I also have the romulator and pocket programmer but when I try to open the rom editor it asks for a registration number that I don't have. Where can I get the registration number from?

 

you have to call hondata and give them the serial number for the S200 before they can give you the registration number for the rom editor..
