    Default Grid Legacy Cable and 8147 Points Box

    Am I correct that plugging the Legacy Cable into the 8147 points box and setting the maximum rev limiter in the Grid, eliminates or replaces the need rev limiter chip in the points box.

    Does the Legacy Cable have to be plugged into the points box for all Rev Limiter settings to work? Problem encountered, car running (never over 4,000rpm) on jack stands, launch retard loaded in the Grid, press and release TB button, 9 seconds later safety rev limiter kicked in. How do you warm up the car, test and record your launch retard program without the safety programs taking over? Will setting the Safety Start RPM at or above the Maximum Rev Limiter RPM (10,500) eliminate this issue?

    max out the limit to 12.5 and the rpm @ 6000 rpm ( just for the test)
