I'd like to put in my $0.02 on this one...
#1 I'm not exactly sure that you're right on the fact that the original 'intent' of the rule was to allow only rechipping and/or remapping using largely the same computer that came stock. I'm not actually sure at this point that the folks that made the rule all agreed on the intent, and it was certainly never stated in the rule.
I actually believe, having spoken with some CRB members, that the ACTUAL intent of the rule was to make it easy to enforce the rule - with so much gray area around what a legal modification was, it got to the point where it was basically impossible to enforce any rule outside of the rule that's currently in place without tracing every single circuit inside the box.
#2. This whole thing about allowing alternate ECU's is mostly irrelevant. Both the MoTeC system and the stock system work very similarly, and either one can be reprogrammed, although reprogramming the stock system takes a fair amount more work (and yes, possibly expense, to do it right) because the documentation of the maps and their locations is not nicely documented as it is with the MoTeC system. At the end of the day, the engine is an air pump. Unless you make it pump a larger mass of air, or compress the air more, or somehow else make the engine have more volumetric efficiency, all the FI system can do (and does) is to optimize the fuel delivery and ignition timing for each set of parameter values (e.g., each combination of air flow, throttle position, engine RPM, and various other parameters, most of which are simply 'correction factors').
Contrary to popular belief, there are very few hp to be gained through the use of a MoTeC system over the stock system, assuming that you can learn about and change every single mapping value in the stock system, which I admit is a pretty big 'IF', but is certainly doable with enough time and money. All that the MoTeC system does is to make it easier.
#3. I am in complete agreement with Darin that it isn't right to negate some competitors current investments in parts and systems for their cars. A good example of this one already happened with respect to the shock rules - we were going to make it 'cheaper' by limiting the number of adjustments and by taking away the remote reservoir shocks that were previously legal.
Now while that may have saved SOME competitors SOME money by ensuring that they did not spend big bucks on shocks, it turns out that you can spend nearly as much money on double-adjustable non-remote-reservoir shocks, and all that we really did is make it so that those folks that spent $1000 each on some nice shocks went ahead and replaced them with some other nice shocks that cost $800 each, and therefore the rule cost those competitors $3,200 each.
Likewise, if we limit the rule to the stock FI box guts with 'chip changes' (whatever that means), you will not be able to prevent a well-heeled competitor from spending money to have custom made 'chips' that effectively imitate the MoTeC box in its entirety. Since I'm not a lawyer, but a software engineer, I know that's very possible to do - it's just more expensive.
OK, I guess I got a little more than two cent's worth...

I just realized that I basically completely agreed with a post by Kirk way back at the beginning of this topic. I don't know what I think about that
