OK Im kinda lost, I have a good deal of paperwork printed out describing what all the functions do, but I really dont know where to begin with my tuning, If I install the tuning adapter without a chip piggybacking it, I will not have any tune correct? ok I found a .Bin file from a factory 92 5.7 a4 factory replacement memcal, opened it up in tunercat and set the manual trans, and adjusted the timing chart down a bit in the upper rpms, knowing the vortec chambers wont need that much timing, it was pretty high. Also is there a way to read the tune off my current chip? My car has always had the primary fan come on , eve if the temp switch is disconnected and I wondered if that was a cop tune thing to keep the engine cool as possible .
