My car has an ecu part number 284b2-1nc0b, software 0610 so I'm trying to buy an old/new bcm but all the ones that I came across with are 284b1-1nc0b is this compatible or I need to get the actual part number? Thanks in advance!

284B2-1NC0B doesn't show up as a good part number, so I have no idea what's in your car. BCM part numbers can be supersessions, but they need to be correct for the car's VIN, period. "Close enough" can render your car completely inoperable. Also, be aware that you probably can't program your existing keys to a used BCM. In general, to employ a used BCM you need new keys, to employ used keys you need a new BCM.

Quick question VStar650CL this is my mec109-072 A1 0621 I found a mec109-036 A1 is it compatible? It shows it will fit but I want an expert opinion before I buy.

I don't know what "it" is, but Hitachi never published lists of which ECU part numbers can fit what. The A1 and 0621 are date and firmware codes and don't mean anything (you can always reprogram), but the 036 means it's a different hardware part. It may have fit the same model as the 072 but with different options, but it's till a hardware mismatch and you'll risk blowing something up. To be certain of a fit, the MEC109-072 must be an exact match.

Ok, cool thanks you explained better than what I could ask.

I found one that's basically the same as the one I have except the date, I believe is what you said about those number on your prev message, do you think I'm going to need to do a reprogram or plug and play given that everything matches?

You'll still need to have a dealer or smithy program the keys (I-key or fathead), and for the ECM it will need CTPL and IAVL procedures and your VIN written into memory. With the same Hitachi p/n it will generally start and run, but you probably want to have the firmware p/n checked and changed/updated as needed. Pretty much the only plug-and-play part in the starting system is the IPDM. The ECM, BCM and IMMU (doghouse) all require reprogramming of one sort or another.

Thanks bro, I ordered the computer will be looking for a smithy shortly.
