Please expand these rules to allow the addition of crank trigger wheels or the explanation that they and other engine sensors are legal to ADD or replace for the purposes of providing signals to the ECU allowed in 8. I believe this to be the intent, but there is no rule (at least none I can find) stating as much.
Allow the use of aftermarket ignition in place of the factory TYPE of ignition. (i.e. allow coil on plug, waste spark, etc.. on mechanical distributor ignition engines). This fits with the category structure of displacement to weight as it is a further limit on potential power for a given engine that is not consistant accross the years and makes listed. such systems are not prohibitively expenive, particularly when ECUs that may control them are already allowed.
