New OEM Genuine Honda ECM Engine Control Module in the box - never installed.

Fits: 1999-2000 Civic HX models (VTEC-E motor), auto transmission, with California emissions.  Number on the part will match 37820-P2M-L71

­Please note!

Honda and Acura ECM (Engine control Module), transmission shift control modules, Valve Body, Safety items, and ABS braking systems require i-HDS and J2534 software to program – this can not be done with just a scan tool.  It can be programmed with other software but it has to be programmed with VIN # input. ​​​​​​​

We do not accept returns on these modules or systems installed and not properly programmed.
