Love it. very good.

Joe hit on some of the points I was trying to make. He did a much better job putting them into words. I think that modifying the factory ecu would make sense in Improved touring.
 
Going back to the original premise of the thread - don't we already have a tool at our disposal to help achieve parity? Wasn't that the whole point of approving PCAs? Something tells me that once we get to the point where well-prepared RX-7s, 240Zs, 944s, etc, can compete with the Bimmers (we're still working on that, right ITAC?) the whole issue of aftermarket engine management systems will become mute. After all, what would I care if the guy I just beat spent 3X as much on his car?

JMHO.

OK Earl I'll buy into that...,Then why slow the E-36 down why not give the 240 a little compression and a little camshaft. Allow the RX7 a little street port(something new to police)....Again once you change the outlook of the class it has to change a bunch to get to parity. I am all for one or the other but lets not be half pregnant here. If Motecs or AEM's can be stuffed into the stock box then lets just get it on and allow the whole deal cause if even one person takes advantage of the full rule then the bar is raised to that level for everyone.

I guess it all boils down to where you want the class benchmark to be - if it's the BMW, then you will have to adjust a few dozen cars to bring them up to the standard. If it's the RX7 or 240, then you only have to adjust one car to bring it back to the group. I think that horse has been beaten about as much as we can though, hasn't it :bash_1_: ?

Agree 100%. I never did understand the whole "stuff-a-motec-in-a-box" train of thought. Either just allow aftermarket systems and restrict the inputs to stock, or keep the factory ECU and allow mods to it. If we were taking a vote I would say keep the factory ECU. As you and Jim have argued I feel like that's more in line with the IT philosophy.

Geo, I don't think your nuts, I think you are biased in your oppinions and you would stand outside in a speedo in a snow storm saying the sun is shining to be right. I don't have a problem with that at least your consistent. You often ignore the other questions brought up on this subject. How do you handle the traction control issue.( I have used it real world) How do you equalize the ability to create an optimum map with traction control for every track in your division? I again am up for discussion but I have to agree with Bill D. here and I said it when the BMW got classed. We pushed the class intent right out the window when we started classing and adjusting things well beyond improved. Open ECUs are not improving anything they are replacing. Thats the problem with the current rule. It should limit to improvement. Other wise we may as well change the name to Replacment touring and get on with it.    :023:

Just a few things in response. Since you have said (paraphrasing) that it's your opinion I'm biased, I can accept it's your opinion. However, I don't see how I'm biased (sincerely).

I personally don't like MoTeCs in IT. However, the issue with ECUs as I see it is that a ) they are impossible to police, and b ) a royal PITA. :) On the PITA part, if we assume that we are going to allow modications (because we cannot police them anyway), then if we are going to be fair to others with ECUs (carb guys are getting a bum deal, no question), then the current rule seems to be the lowest common denominator (considering ALL of the ECU equipped cars in IT and not this brand of that). I HATE where we are at with ECUs, but honestly don't see another workable solution.

As for traction control, doesn't the MoTeC use some sort of algorithm to limit how quickly the revs may ramp up? If not I don't see how it could be done legall unless somehow some car has the wheel sensors wired to the factory ECU. I don't know the answer to my question here, but just guessing. I know you are intimately familiar with the MoTeC so I'm sincerely seeking your knowledge on the matter.

In the end, I'm all for requiring stock ECUs if we could police them. We just cannot.

Well the AEM system does not require a wheelspeed sensor to use the traction control and I am sure the Motec is the same way(I have not tried traction control on a motec application.) but since both systems also data log the wheel speed sensor becomes legal because data aquisition is considered a gauge.


I know we have beat this to death so as I said I don't care as much as just sharing information here.

That's my interest as well Joe. Here is what I have a problem with above: You may data log the wheel speed sensor, but how do you get that info to the ECU? If the factory wiring harness does not feed that info to the ECU, how are you going to get it there? I have no problem with that info going to an instrumentation package. I just don't see how it can get to the ECU legally.

Back to my last question about how the two systems do traction control, it seems to me the only real way they can do it w/o wheel sensors is to limit how quickly the revs may climb. I could see this being more of a hinderance in road racing.

I'm not trying to argue with you, but trying to explore this some more.
 
My only question for those would would vote for the factory ECU is:

How would you propose it be policed?

Again, I'm not looking to argue, but that is a valid question that absolutely MUST be addressed if anyone wants this to be seriously considered.

Again, I'm all for it, but I just don't know how to make it work.

If we are going to this much trouble to stuff the box you think I can't wire the factory data port to serial feed my lap top? Geo there are 16 year old rice rocket kids that can do this stuff these days. I believe that's why it is so hard to get our arms around. We learned on a toilet system with jets. B)

No physical modifications allowed. If a tech inspector opens up the box and it's been modified, buh-bye.

Sure, there'll be some cars that can program without physical mods; there will be others, like me, that cannot. C'est la vie. You can't account for cheaters that may modify their boxes on the sly, but what it will absolutely do is limit any mods to those that can be done via the OBD port and such. The ITAC and CRB can keep this in mind as later cars are classified. - GA

Greg I would almost agree here except the CRB has finally come to the acceptance that they can't police any of the classes. I think that's the trend toward touring from SS.

I don't know enough about all the ECUs out there to know if this is 100% accurate, but I find myself debating if this is a legitimate argument against implementing this rule (any rule for that matter). How many other rules do we have already that are so difficult to police as to make it virtually impossible? How about the engine coatings rule? Or the rule about lightening cranks & flywheels only to the point of balancing? I'm sure there are many examples, the point is we rely so much on the honesty of the competitors already why would this be any different. I tend to believe that the guys out there who play by the rules will do so, whether they believe the rule is enforceable or not; and the guys who skirt the rules will do so regardless. JMHO.

I tend to go along with Greg's approach to the policing question, with one exception - you have to find a way to allow the elimination of the speed limiter in cars so equipped. I don't know if you can accomplish that on every car out there without some physical modification to the ECU, but that's the only problem I have with the "totally stock" ECU rule.
 
I just can't take it anymore. How in the hell does scca justify $3k ecu's in a class were I can't remove my windshield fluid bottle because "that is rules creep". It's just silly. You have ITS cars (ok Chet) running within 2 seconds of E prod national times. Some where we lost the handle on what IT is supposed to be. If we feel that we have to allow motec and similar systems, then they should come with a wieght penalty. Say 200lb for alt. ecu, 100lb for traction control, or 50lb for ABS. That is the only way to let the rich have ther toys without making the non-rich uncompetative. Scan the other chat rooms; prod, gt, sm. There are a lot of ticked of people in this club. We have some real venom circulating. I hope whoever steers the ship next looks into the real issues driving members away from the club.

Step back from the ledge..... :happy204:

Rick I have to tell you that right now at this moment in time you have the best group of AD-Hoc guys probably ever. I believe they are working hard and have worked hard to fix a few of the deep rooted issues in IT I believe for the most part they have theor eye on the ball as far as possible corrections to thing that were wrong the past.
I also feel that at this moment in time we have guys on the CRB that are listening to the plan and executing the best they possibly can. I don't know what the future is but there are a few people in place that I have big respect for. So remember we didn't get here over night and it won't be corrected over night but it looks like the tide is turning a little.

:lol: That's a good one Joe.

I understand what you're saying. Don't forget that while I'm building a 944 I'm a pretty serious Nissan guy too.

However.... we still have not addressed how to get wheel sensor info to the ECU legally. Unless the wheel sensor was originally feeding the ECU, I don't see a legal solution.

We also haven't addressed how the AEM and MoTeC actually control traction w/o a wheel sensor. The only way I have been able to dream up is an algorithm that limits the climb rate of the rpms. I also am doubtful of the use of that in road racing.

Again, not trying to argue, but these issues have been put out there so I'm exploring them. If there is any information that you have that relates to this that you don't wish to share publicly, I understand that as well. You have a business to run and you have invested considerable time into these areas.

You know, I've been running IT for 12 years now. So I've had this discussion with more than one person. But the hardest thing to explain to non scca or new scca people is what our rules are, and why we have soooo many classes. After a while we become numb to it. But you can always spot the new guy at annual tech, or registration, or impound. He's the ticked of guy who just keeps saying "you've got to be ^$&*%#$ kidding me." At some point we need to become more user friendly. I'm not a fan of nasa's every car gets it's own class, or nascar's our way or the highway, but somewhere there must be a happy medium where the rules a straightfoward and the emphasis is on doing your prep work and driving the car. Don't say spec miat because that is a joke in it's self. I don't have the answers, but with today's "take my ball and go home mentality" we need to have stability and simplicity enter the equation somewhere.

Um, so your vote would be to require race cars to have speed limiters, as long as we could police it?
