Hey guys, I have an issue I can not figure out. I have a rb25det in my 1990 z32, I just got my z32 ecu modified to run a rb25det and Nistune type 2 board installed on it. I can not connect to my ecu on my laptop, every time I try to connect to say Consult not connected COM6:spare, or what ever port on my computer I am plugged into. I have checked and double checked my wiring and test ohms from the consult plug to the ecu plug and everything is good. I have good power and ground. I have checked the diagnostics to make sure my ecu isnt in limp mode. comes up with code 55 ( no current diagnostics) and started my car and it runs and revs over 2500rpms. My computer ports seem to be working fine, they see the consult interface and knows its by Nistune. I don't know what else to do or check?? Any ideas??
