Big Stuff 3 - Distributor based 1st Gear Spark Retard & Spark Retard (SR2) Upgrade

This upgrade is the new 1st Gear Spark Retard with Spark Retard Traction Control System (SR2) and uses two independent timing retard systems to control driveshaft speed. Both systems are triggered and function simultaneously. The 1st Gear system uses timing retard as a function of RPM to control the tire in first gear. The system also has user configurable "Time-Out" and "Blend" features to eliminate "sticking" the tire, and ramps the retard timing back to zero. The second timing retard system works in conjuction with the first gear retard system and can intervene at any time. The second timing retard system controls drive shaft speed for an eight (8) second time period using a drive shaft error table to apply user defined timing retard values to control drive shaft speed.

This upgrade is for distributor based BS3 systems
