Need help: Donor ECU

Im having some serious freaking issues with my car. I need to borrow an ECU from someone that is tuned for 550cc injectors and a Z32 MAF for an sr20det. But the important part is that i need the little screw on the back off the ECU to be in good working order to check an ECU code. If anyone has one i can borrow i can offer some beer, or maybe some cash. PLEASE HELP!!!
