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

Fits: 1997 Prelude auto trans, with California emissions only

OEM # to match: 37820-P5M-L52, 37820-P5M-L51

­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.
