Well, considering I once spoke to a programmer who had Bob Long ask, in a roundabout way, if he could reprogram a board with a self-ramping dwell, and the fact that WAS boards have both an adjustable (to near-zero) triggerswitch debounce and shot-queuing (storing) I think it can be said without fear of contradiction that yes, people are indeed using "cheater" boards.
Depending, of course, on your definition of a 'cheater'.
The All-A's used a "cheater" board in '98 with the first Shocker Turbos. The rules didn't specifically say they couldn't use "switch noise" and didn't specify precisely what constituted a 'trigger pull", so they got away with it.
Do you think the idea has been abandoned over the past five years?
Doc.
