What cars as time goes on?

I do not think that the SCCA needs new classes. I do think that we need to allow the current classes to evolve with products that the auto industry makes available to us. That may mean that my 20 year old ITB car will not be competitive in 5-10 years (of course I will do my damndest to keep it competitive), and I am OK with that if it maintains the health of the club racing program. If the time comes that I need a different car and/or class to be competitve, I will take that step.
 
Swah-you can connect or disconnect the front sensor-it only conrols mixture at part load when you don't much care about tuning, and the part load maps are fine without it as well. I'd recommend removing it and putting a wide range sensor and display in it's place for tuning/peace of mind reasons Phil

And that would be legal why?

EDIT: Oh, I see what you're saying, just for a display, not to hook up to the ECU.
But this brings up another question: why is it legal to remove an O2 sensor at all? Is it?
 
I/m not advocating any new classes-just a limited prep aproach to ne B&C cars in the area of engine prep.
Shouldn't be hard to move backwards in that area, make newly classed cars equal to existing ones, and gain in economy (cost) and reliability. No more need or grey right to deck and overbore blocks. Phil
 
You are right, upon re-reading ITCS 1-d, it is very specific about the EGR portion of the emission control system, and does not address the overall emission control system.
 
Re: limp mode
I don't know of any European management system that goes into limp mode when rear oxygen or vehicle speed sensors are disabled Phil

I will endeavor to prove or disprove this weekend. I hope you're right, but the experts tell me otherwise.

If it does cause a problem, my letter will ask for an exception on the spec line allowing alternate ways to disable these systems as opposed to a wholesale change to the IT rules, because I think that's a more realistic request. My goal is to get this car on the track without a custom ECU.

Well, I didn't feel like waiting until the weekend. Sure enough, disabling all four wheel speed sensors throws a code, lights the check-engine light, and causes the car to set a 5300rpm rev limit.

I did a bit of research, and found out that the right-rear wheel speed sensor is also used for freeze-frame data for the OBDII system. Even though the speedometer works off of the differential, the OBDII system reads the vehicle speed from that right rear sensor.

Leaving that single sensor connected disables ABS and TC as required, (as it cannot compare the right rear wheel speed to anything), but keeps the ECU happy.

Letter already sent.
