We will not be flashing any ECUs Friday 12/21/2018 - Friday 01/04/2019. Any ECU received during that time will be flashed during the next week. Please plan accordingly.

How Can I Re-Flash my ECU?

Re-flashing your ECU has never been easier. All you have to do is send us your ECU to:

Guhl Motors

102 S. State St.

Ephrata, PA. 17522.

Inside the box with your ECU, make sure to include your name, phone number, and return shipping address. Once we recieve your ECU, we will contact you to go over the options for the re-flash, and lastly, payment information. Once we're done, we can send your ECU back to you and you can feel the Guhl derestriction difference!
