ok ive debating on this for a bit...
ive been lookin at this thing from yashio factory in jpn....
and since i rewired my ignition on my ka24de previously with awesome result..ie spitz fire....
i call it an ignition harness current upgrade....
i ve done it on my car with no issues ...
first link is yashio factorys...harness
http://www.yashiofactory.co.jp/cam_p...main_p_bnn.gif
and this my prototype which is running on my car
all done with soldering and heat shrink with 8g wire and regular 40a relays

and how it looks in the engine bay

i kno ive got the coils hot..cause if i play with engine revin up or driving hard as hell..she blows fire ..sumtimes blue...and sumtimes orange....
lmk wat u think

 

can please tell me how to do this? is seems simple enough and I know enough about wiring to be able to understand all the YF harness is is a relay and larger gauged wire... i just don't know how to setup the relays/which ones to get...

Thanks man!

Would love to try this to help with misfiring issue, even though it may just be the coils, this would help either way.
