After all these years. Stumbled across how to get one over 5,800 rpm. It works and works well now. Working with a 350 capable of doing 6,500+ this weekend. Set the last cell in the minimum dwell time table labeled 2,400 rpm from the factory 2.004 to 1.75 msec and 6,500 limiter now. The computer was commanding minimum dwell time at high rpm that exceeded the amount of time available between coil firings resulting in ignition misfire that felt like a rev-limiter. The Black Box can finally rev out over 5,800 rpm. Wish I had known this 15 years ago! The 0411 has shorter dwell as the rpm increases. 1.75 should allow for atleast 6,500. The feeling before altering the dwell time was exactly the same as the old TBIs when the injectors went static. It would lose power and misfire. What pisses me off is years ago I gave up on trying to get one over 5,800 and the problem was in plain sight.
