Will me having a h22a p13 obd1 4w (4ws) as an ecu make my car throw a code and send it into limp mode? I have a 4w p13 ecu now and its throwing codes and its redlines at 6800. Its also a 4 plug ecu. different people keep telling me that its automatic cuz of the 4 plugs and so people tell me that its for the atts. Now which one is it?
