Im going to fire up the car friday and run diagnostics using Nissan DataScan. Are there set parameters for the 300zx. What i mean is, when i open up the data display and view all the numbers being fed back, how do i know what it should or should not be. My air flow is reading this, but it should be that. Is there a set of parameters your basing this off of, or does is datascan given the parameters straight from the ecu. Ive been reading the instruction manual on how to use the tool but wont be working in it untill friday.
