Tuning for maximum performance can be done with either a carburetor or an ECU. A couple of advantages the ECU has over the carburetor are data collection and prevention. Algorithm’s can be developed to give specific data like 0 to 60 MPH, time to get to 1320 feet, etc. Preventing heavy engine and vehicle damage my include fuel shut off for loss of oil pressure, miss shifts, driveline breakage, misfire detection, etc. You might not prevent a spun rod bearing but you might be able to prevent the connecting rod going through the engine block. The use of tools with specifically designed algorithms is the key to real performance advantage.

It sounds like a significant challenge! I wonder if (given the limited number of runs per engine) anyone can be sure that they are getting the most out of the engine? Could there be a way to test drive the engine/racer at slower speeds to calibrate the settings prior to high rpm operation? These motor controllers clearly seem to work but I wonder how much better they could be if a different approach was used say modifying a test stand for use with the dragsters (maybe not optimal but would it get better results sooner)? Just wondering what has been tried in the past.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
