14 is ignition circuit, if I remember you used to get that through boost cut. What MAP sensor are you using?

21 is O2 sensor

31 is MAP sensor

47 is TPS related

 

They may be due to a failing stock ECU, you haven't said what the spec of the car is. Honestly, best advice is to get rid of that emanage, its so old now and spend money on decent management, Link stuff is cheap and well supported now.
