Jdm Ecu

I recently bought an ECU for my prelude off Ebay and I dont think its the right one. Someone said it might be a JDM ECU. No one seems to know what car its for and I dont think its for my prelude. The number above the barcode is 37820-PCF-901. Im almost postive 37820 is for a honda but the PCF-901 no one seems to know. For my prelude it should be a P14. Does anyone know what this ECU is for? Someone said possibly a JDM HOnda Accord 2.3L auto. IF anyone has any input please let me know.. THanks

I did a google search of "honda ECU PCF" and all of the hits came up as "JDM HONDA PRELUDE 2.3 VTEC ECU AUTOMATIC" So it looks to be for an automatic. Do you have a vtec engine or non-vtec? If it's a non-vtec then you should get the P14, if you've got a vtec engine then you want the P13.
