New OEM Genuine Honda ECM Engine Control Module never installed. 

Fits: 1998 only Civic HX model only, manual transmisison only, with California emissions

OEM # 37820-P2N-L31 must also match on the part.

­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.
