Hi, I own an Acura RDX here in Mexico and I want to get the reflash from hondata either by sending my ecu or buying the complete ecu they sell. My question is, how do I know it will or will not work on my RDX?

So far hondata has just tell me that they dont sell the product for my ECU number which ends with RWC - X56, instead of the US version A56 or 57.

Does someone here know if there is an important change in the ECU's in a way that one can't replace the other? or can someone give me a contact from Acura to ask this questions? All I hear is ask your dealer, but dealers here in Mexico have not helped me at all so far.

Thanks.
