iv a uk prelude2.2vtec 1998,iv just swaped the ecu for a jdm prelude 2.2vtec 1999,the car runs great,but get a cel when i drive it hard the cel is "11",thats one long beep followed by on short beep,think this may be "camshaft timming to far advanced".the original ecu was a P5M-G63 and the jdm one is a P5M-N51.
if you didnt see the cel light you wouldnt know anything was wrong.
any help on this guys?
