Ask a Question
  • How will the emobilozer work with a different ecu. I see with sending my original ecu they require the key and emobilozer usually. Will the light on the dash just flash then? Im leaning towards getting a reconditioned ecu rather sending mine in with key since I only have one.

    Thank you for your patience.  You have two options, you can either disable the immobilizer within the calibration file/basemap you are using, or, you can have your local Honda dealer program/sync the new ECU to your vehicle's immobilizer.  Hondata has a guide on this available here: https://www.hondata.com/tech-immobilizer-re-key
