I thought that too until the SCCA allowed aftermarket diffs in STR. I was one of the many that voted no but it happened anyway. I think you make a valid point.

Well done! After reading through it in the details section you did not mention rev limit increase that is easy for flashpro users and difficult with piggybacks. There is a solution specific to 04-05 S2000 using the AP1 ECU but AP1's and other cars in ST may not have this capability with their respective car models and piggybacks. This is part of the jumping through hoops to be equal. Not sure if it is also worth noting the difficulty in finding piggyback tuners, most avoid and focus on standalones.

The rules equalize what can be done to any car in a given category, not an individual car's ability to exploit them.

If you want to talk about making things truly "equal" with rule changes, you should also look into getting 500+ lbs pounds out of every S2k to make it "equal" with an NB and then letting the NC and NB have turbos to get 230 whp like a tuned AP2v2. Then it's on to track width, wheelbase, etc.

This kind of argument is a slippery slope.

Yeah, I don't think the equalization argument is the way to go here. The argument is simply, standalones do not allow anything that isn't already doable now (with enough money, knowledge and perseverance).

I think you misunderstood the equalization argument. My intent was not extreme to go down that road to equalize accross makes an models. Maybe my focus was too specific without consideration or understanding of the impact that would have on other makes/models. The current rule does not provide the same capability within the same make/model in a cost effective manner if that was the intent of the rule. It should not favor certain model years or technology advancement and capability as the model evolves over the years. Having recently gone through this and still working on it, it really sucks to get a piggyback to be tuned to have all the capability a flashpro user has. In the end it would have cost more than a standalone would have, and you are right i had enough money and perserverence to get it done. It looks like from an ease, safety, and cost perspective it is easy to find a tuner and tune 06+ cars using flashpro which is equivalent to standalone in 00-05 MY. If you think this equalization argument is weak then don't include it, it was just a suggestion to support the points you already made. Other makes/models may be experiencing similar frustration and may support it.

Thanks Tony. I don't think the argument is weak but it does tend to cause people to go down the path of other equalizing things under the rules. The proposed banning of the R1R for instance is one such thing where I feel the NA miatas could really use the help of that tire which is currently legal under the rules of treadwear and keeping things as is would be a good equalizer where as eliminating the tire would in fact almost make the NA miatas non-competitive in STR.

But I digress. I want to keep the argument as simple as possible to minimize frivolous opposition. As it stands, on the sccaforums thread I have already gotten some negative responses (as expected) yet none of them have been able to provide a single example where a standalone can do something that is not already legal and doable under the current rule set using either a reprogrammed ECU or a piggy back. People are very adverse to rule changes and rightly so in most cases but in this case, I think the writing is so clear only someone who hasn't been keeping up with ECU and tuning technology would blindly oppose it.

For the 04-05 AP2 guys that want to raise rev limit. I just swapped over to an AP1 ECU and had it programmed today to work with my keys and immobilizer. I brought all spare keys just in case, and i am glad i did as it was done for each key.

I searched previously and could not find the answer if i would need to program again to go back to AP2 ECU. Even they guy doing the programming did not know the answer. I have now confirmed you can switch back and forth between ECU's with no additional programming and I can go back to stock whenever i want.

I have not hooked up my EMU yet to know if i will have the AP1 harness issues.

Any idea what the price would be for the average person to get the keys programmed?
