wait wait....which ecu are you using....you took his s5 motor and put it in ur s4....are you running your s4 ecu or the s5 ecu?

Im runnin the s4 ecu I used only the bare motor and changed the front cover.....I have the s5 ecu but it wasnt compatible with the rest of the plugs so I used all my stock parts n put it on the s5 13b.
