(Answer, it sucks, but hitting the net or ebay and scoring a washer bottle sucks, but is better than going to the dentist...)
Simply, does the risk/reward ratio work?
Each category has it's strengths and weaknesses....nobody will love EVERY aspect of every category....that's life, LOL.
It's fine to say, "If it doesn't work, just repeal it".....but that is very tricky in real life. One of the things that has TOTALLY (and rightfully so) pissed off members is the post rule change reversal. Reservior shocks comes to mind, as do others. It has happened in classing too....mistakes made classing certain cars have rendered entire classes as backmarkers.
Funny thing about the ECU...errr PFM,....errr...PFMS or whatever you call it...situation....
When the rule first came out, it was an attempt to level the field, but manage the ramifications. It was a knee jerk reaction based on the inability to detect and enforce the rule. The result was some tricky and enterprising folk spending lots of money stuffing things into (certain) ECU boxes that nobody thought could fit....and thereby raising the game for EVERYONE..AND upsetting the competitive balance. A DOUBLE whammy! (Cars that have no ECU can not tune the spark and fuel delivery maps equally, thereby the comptetive balnce was altered, as the change came POST classification of certain cars, and if you had a car that benefited form such mods, you now HAD to go do them if you wanted to run at the front. And lets presume that, as racers, running at the front might be desirable...)
A valant but flawed attempt would be a charitble summation.
And it is a huge Genie that fights cunningly to stay out of the bottle.
But...this might resolve itself, to some degree at least, and the irony is the same advancements that made it suck, might make it better. The march of progress on the data memory and mangement front is bringing the computing power to more and more racers So, a little rebalancing might happen.
Even still, if somebody has any way to jamb that guy back where he came from, I would be all ears.
