I'm working on an s4 usdm turbo to s5 jdm turbo swap. I'm swapping, engine, trans, wires, and ecu. I'm only running into one problem that I've never seen the answer too, and that is...
Do my s4 coil packs work with an s5 ecu? (with any necessary wiring)

Please spare me the "you should only swap the block and use old sensors" and all that, I don't have anything that was bolted to my series four block at all.
Thanks in advance.

 

they will work.

 

Simple enough. Thank you oh so much. *crosses fingers on the rest*
