There is not yet an answer as to the failure modes involved in the DI failures. Nobody has identified any "electronics" in the units and even if there is, that might not be the cause of the failures. After monitoring this thread for a week or so, I'm beginning to wonder if the DI is a case of suboptimization. The distributor, HV coil, and sparkplug wires have been eliminated, but these were relatively inexpensive items and rarely failed. These were replaced by multiple expensive items which are just as prone to failure if not more so.
