I hav just upgraded my 87 305 TPI to the ARAP.bin I'm still really new at this and I'm scared to blow up my motor. I attached the bin that I'm using. I'm using the 6Ev009.ecu Also I attached two cvs files. The GM072701.CSV is what I captured when I started it for the first time and let it warm up. It seemed to be running OK s I took it around a couple blocks and I stored that in the GM072702.CSV file. I know I have some rich and lean spots but I don't know where to start first. Do I try to adjust my fuel in the MAF tables? Or do I start with Spark? I didn't seem to get a lot of knocks so that is good. I doesn't seem as simple as it should be. I just don't know what affects what.
