As I start collecting data one thing one has to rememeber is the condition of the car or truck your working on. The testing equipment in that test. I'm using two scanners a Auto X-Ray EZLink and a newer Actron CP9185 both do obd1-2. The newer scanner when hook up and scanning runs the Idle up an extra 100-200 rpm's I down load new updated software which helped so now it only idling 100rpm higher. All the data looks the same from both scanners at the same rpm's so I will keep using it to print my data out.
First up we did a idle test with the two scanners recording a run cycle about 20seconds long at normal operating temp of 195. A driving test 45 mph and a freeway test at 65 mph. With this data we know the truck is running normal show no codes. On to smog testing next!
