I don't know for a fact but I'm very sure all BMW's use the 0-1v type of lambda, if it's running rich then it's time to check the blue(?) engine temp sensor and then read the fault codes for the lambdas and check they are switching 0-1v under running conditions.

Im running a 1 wire e30 2.5 sensor so that a i get a temp display on dash i wonder if this is causing problems

Stock E30's have two sensors, one brown for the instrument cluster and one blue for the engine ECU which fails regularly.

i dont know if they are working correctly or not tho really, e36 sensors have differnet colours to m60b40 so maybe they aint matched up right
