Metallicar Posted September 12, 2007 Share Posted September 12, 2007 I want to do the Z31 ECU swap. I now only need the ECU to make it happen. I have everything else. I picked up a 85 ECU but it is in sad condition. The P.O. claims the car was running fine with it in the car (the car was wrecked). Here are some pictures of the boards. Can I clean these up safely? With what? I remember seeing boards cleaned with Refrigerant 11. Is this a good option? I still have access to some R11, R12, and others. Thanks for your help!

TONY C Posted September 12, 2007 Share Posted September 12, 2007 when I built my MSII the directions said to lightly scrub with a tooth brush and 99% isopropyl alcohol not the 70% version or acetone. I would use the isopropyl alcohol. I don't think it will melt anything like the acetone might Quote Link to comment Share on other sites More sharing options...
