if you insist on going mafless just set your maf hertz to 2 and 1 and your high rpm enable to 8100 and disable to 8000 and set all maf dtc to no error reported. since you dont have a cam it should run fine. im sure someone will say no but this is what i would do. IAT sensor is also in the maf sensor so it will not pull timing when you are driving in hell
