i just want to know if theres any difference betwheen an ECU model number: 77960-S6M-A912-M3 and any of this 77960-S6M-A921-M3 or 77960-S6M-A931-M3 or 77960-S6M-A920-M3 and such.. is there any difference or any of those would fit my acura rsx type s 2002? mine had the A912 but i cant find the same anywhere.. they all say a different number like A921, A920 or A931 and such but they all say fit acura rsx type s 2002, im a proud owner of an rsx 2002 type s.
