If you suspect your ECU has a software issue, you will need this cable to connect our fuel injection system to your personal laptop. We can then remote in and re-flash your ECU with the same software we ran during CARB EO testing to ensure the problem is not due to a corrupt software file. Alternatively, you can mail your ECU to us for a fresh flash.
