Don't Miss Obd1 Ecu Hondata S300 Socketing / Installation Service Slash 60% Off The Price [l19bnf5H]

This service is for customers who would like us to install their Hondata S300 system into their stock OBD1 ECU. All labor is included in this service including final testing to ensure that your Hondata S300 ECU operates correctly upon shipment.

For our customers who are purchasing an S300 system from us, simply add this service to your shopping cart and let us know you are sending in your ECU for installation. We will hold your Hondata S300 system for you and wait for your ECU to arrive for installation. Turnaround time is 1-2 days from the time we receive your ECU. For turbocharged applications where you would like to use the boost control features of the S300, we offer our PWM boost contol installation for seamless integration with the Hondata S300 unit as well as the Hondata Boost Control Solenoid.

  • Professional socketing for use with the S300
  • Hondata S300 unit is fully installed into ECU
  • Includes ECU case modifications for USB access
  • ECU board is thoroughly cleaned and inspected
  • ECU is tested for proper operation before shipping


NOTE: If your ECU has already been socketed for a standard 28 pin socket, we will need to remove the standard socket to install the S300 style pins. In doing so, the ECU board may be damaged. We HIGHLY suggest sending an ECU that has not been modified for our S300 installation service.

Replace Capacitors option: OBD1 Honda/Acura ECU's are now 20+ years old. Over time, the original capacitors may begin leaking and fail, causing damage to the ECU board and ECU failure. If you'd like to have all of your ECU's capacitors replaced while it's here (recommended), simply select this option and we will replace all of your ECU's capacitors with new capacitors!
