Hey I am looking to buy a 98' JDM Type R ecu and need to know the difference in codes within the 96-98 JDM Type R ecu's, i thought that they were 37820-p73-003 and all the same but my friend has a right hand drive 98 JDM Type R straight from Japan and I pulled his ecu out and the code is 37820-p73-013 so now I am confused and I know that the 98' USDM ecu code is 37820-p73-A03, I figure that USDM has p73-A.... and that JDM has p73-O.... and that is how to tell them apart, but know I cant figure out what the p73-003 ecu is out of, I'm thinking 96-97 JDM Type R's but not sure, please help if you know anything, thanks!!!

 

Can anyone help????
