Is the only difference between the hks twin power for a rx7 and rx8 the harness or is the unit itself different as well?

thanks

 

anyone?

 

I believe they are different.

Functionally the FC3S and FD3S Twin Powers are 3 channel and have 2 CDI circuits because the trailing ignition fires so close to the leading ignition.

The RX-8 Twin power should be 4 channel because there are 2 separate leading coil packs rather than sharing a single wasted spark. I would guess its possible to get the RX-8 unit working with a real 4 channel ignition standalone and some wiring work.

 

Thank you. I believe you are correct. I did some more digging around and it looks like they are different.
