Question:

Hi. What does send ECU in first mean? Just a bit confused. Do I send in my Ecu and then you mail the new one or if I purchase this ecu for $500 dollars you send in according to the mail route I have selected? With this price, I would assume I am purchasing this Ecu only, no mail in replacement. I'm buying it, you send it and I do NOT need to mail in my old Ecu.. Please advise.. - Jay

Answer:

Hi Jay, you can either send in your ECU to have them upgrade that, and avoid the core charge altogether, or you can pay a core charge, and they will send you an already-upgraded ECU, with the option to send in your original ECU after to get that core charge back.
