I did download Forscan and waiting for cable to hook it up. In LiveLink, the label says “SPARK ADDER KNK SENSOR ARRAY” That sounds like it is all the cylinders. The graph line goes up in a stair shape and goes flat for .5 to 1 seconds and falls erratically. The highest value is +7.5. Other datalogs the highest is +5. I’m tied up for next two days, so Wednesday is the earliest I can work on car.
