My friend's running an s5 w/ s4 longblock stuff and s4 ECU.... Is that bad? LOL

Aight well i tested to the coils today and got spark from both leading and trailing so i dont know what to do now. I tried goin to the factoy service manual online to look for help like rotoryordeath suggested but it wont open for me, it just keeps freezign my computer so. Im going to try and figure out what to do about the timeing so i'll keep yah updated.

I didnt know you could run a S5 engine with a S4 ECU. Learn something new everyday I guess
