Apexi Power FC question
 

Hey guys,

I have a 1995 FD (JDM model/RHD) and i'm wondering if the various versions of the apexi power fc available will make a difference. On occasion in the used parts section I see either FD3S4 or FD3S5 for sale. What's the difference between the two?

Thanks in advance

From what I think I remember,

FD3S4 ECU is 8bit for 91-early 95
FD3S5 ECU is 16bit for 95-98
FD3S6 ECU is 16bit for 99-2002
