Exclamation z4 ecu

hi bud
still running rough.. changed ecu back to u8
ran better but not when i first had the car
changed sparks..checked coils no probs..
cel light keeps flashing continously...showing no fault codes what does the cel mean
no codes reported??
what do you think...checked maff..cuts out when upulgged...unpulgged lambda no diffence in running running v power...
seems to be running rich though? still lumpy?
seems to boost a bit ..but not has it should..

Are the black and green connectors disconnected because as far as i know they shouldn't be connected during everyday driving.
The CEL flashing means no faults have been found IIRC (which you've stated in your post)
