Hi folks,
I've just fitted a performance chip to my M52'd E34. I'm running all the M50 ecu and sensors and had no problems before. The car is pulling like a train when it is started but it takes a lot of cranking to get it going. The guy that supplied the chip suggested the ecu might be to learn the new fueling and to live with it a while but I'm worried I might burn out the starter motor. Any similar experiences this and is there anything I can do before I put the original chip back in?
