Sorry, now I remember, it was in Jan 08, NHRA accidentally had a sentence that outlawed all driveshaft logging, that was quickly rescinded as it was found to be a typo. The problem with the rule as it is, is enforcement. Driveshaft RPM logging is legal and crucial (at least to me) to figuring out track conditions. But expecting a tech person to determine if that line is then being used to control the ignition, is a complex wiring issue. It's probably best if they do what they do for many other rules: respond to complaints from competitors, and examine cars that appear to be violating the rule.
