This will be boring to some, but interesting to the information-junkies, I've posted a TXT file that contains data collected from a GM computer in a 1/4 mile dragstrip run. It was a high 12 second run with 20PSI of boost. Things to look at and compare are; RPM Throttle position and OXYGN-VOLTS. This is from a turbocharged 4.3 V6 GMC Truck, so the O2 redings are a little on the high side under load to keep from melting the cast pistons. Anyway, it was gathered at approx 4 frames per second, so you can get an idea of how quickly the O2 sensor reacts to mixture changes. Four frames per second isn't fast enough to cover *everything* the O2 sensor is doing, but it definitely gives you an idea of what's happening. O2(OXGN) volts ( is in the 11th or 12th collumn.
