In the REV LIMITER / SETTINGS tabs, the Safety Run-Time uses a default setting of 12.5 seconds. I recommend leaving this setting during initial set-up. The Safety Rev Limiter has a default setting of 2,000 rpm. This value should be raised to 3,500 rpm. The reason for this is that the engine will be rpm limited to this value while shutting down and driving back from the end of the track. To disable this feature, enter an rpm value that is the same or greater than the ?Maximum Rev Limiter? setting. To Tune this feature to the best settings, reduce the Safety Run-Time by 0.5 seconds every run, until you see activity in the ?Rev Limit Active? channel in Data Acquisition during the run shutdown. When this activity is achieved in the display, return to the previous Safety Run-Time setting. DO NOT use a Safety Run-Time setting ?Less Than? your elapsed time plus 1.5 seconds. Example?. A 9.00 et car should not have a finished programmed setting of less than 10.5 seconds in this example. You want the ignition to fire every pulse unlimited during a ?normal? shut down.
