Overview

The Honda 37820-PRB-A15 is an ECU (Engine Control Unit) designed as an OEM replacement for select Acura RSX models.

Show original supplier description
The 37820-PRB-A15 ECU with Programming is a direct replacement engine control unit for the 2005 and 2006 Acura RSX. To achieve a plug-and-play installation, the process involves purchasing this replacement ECU and then sending in your original unit. Module Mechanics will transfer the data from your old ECU to the replacement, including your VIN and security data. This ensures that the replacement unit will start your vehicle with your existing keys. The entire service, from purchasing to receiving the programmed replacement ECU, typically takes 5 to 7 business days, accounting for shipping transit times. Once you receive the replacement, simply re-install it, and your vehicle will be ready to go without any further calibration or programming. The replacement units are tested OEM pre-owned parts and include a 2-year warranty, with an option to extend to 5 years. While the part number may vary slightly, compatibility is guaranteed. The seller notes that in most cases, data can be extracted from damaged or flood-damaged units, provided they were functional at some point.
