Please include copy paid invoice with ECU and all of your contact information along with phone number and address. Make sure to package your ECU tightly with lots of padding to protect from impacts. A good rule we use it should survive a drop from 6ft. OEFI is not responsible for ECUs that arrive damaged. Always insure your package.

If you would like to use one of our authorized dealers to flash your ECU check out the dealer map below.

If there is no dealer in your area and you have a trusted marine professional have them give us a call and we would be happy to set them up as an authorized dealer.
