i'm seeing 9-10:1 a/f ratio at idle. car worked great when the turbo on, now its really rich naturally aspirated. i reset the ecu etc. anyone have any ideas? i sent it to a honda specialist and he has no idea whats causing it

Better that than real lean... Do you have a different cam? Is the timing retarded a lot to keep from detonation with the turbo? Cuz that is one high a/f ratio.. Try advancing the cam see if that could lean out the mixture a little... The whole turbo to NA throws me though... Turbo's can do a lot of things to engines...
