TCS and flight judging

[Steve P.]

In looking at the 68-72 performance judging sheets, page one indicates in the cold engine start section,TCS System(if equipped) . My question is, that my TCS system on my 71 has been removed from the car years ago by a previous owner and if the system is gone, then it would preclude the car from passing the performance test, as one failure terminates the test.. With the performance test fail, it would exclude the car from being able to receive any classification in the flight class. So not just a deduction, but an automatic fail if the system is not there? There is also a deduction of 25 points in the operations section checklist number 18?sorry guys but I'm confused? Again!!! Thanks Steve

It could fail a PV but you still could get any Flight Award. Don H.

Re: TCS and flight judging

Don is correct - no way to pass PV without the system; but certainly possible to attain a flight award, and more than likely a Top Flight

It will receive a 25 point deduct during Flight Judging 'OPs check'. No failure during that part of the process precludes moving on to the rest of the judging. Expect further deductions during the Mechanical section for the absence of components.

It's only during a Performance Verification (PV) where a single fail will cause the test to stop. A PV is not part of Flight Judging.

Thanks Guys! That does clear things up, as the way I read it was that one was dependent on the other! A few things to sort out yet but it's getting close! Cheers and thanks again, Steve

Hi Steve,

1971 Corvettes were equipped with the "CEC System" Combined Emission Control. The deductions could vary with each operation judging, ease of start, cold starting, non operating CEC, etc areas where points could all be taken. As MW states, mechanical judging would result in, additional deductions.

Hi Steve,
Although you say the parts to your 71's system are gone…. it's called CEC (Combined Emissions Control) in 71 only… my bet is that at least a couple of the parts are still there.
The system consisted of the CEC solenoid mounted on the left front of the carburetor, a delay relay and reversing relay mounted to a small bracket on the firewall, a temperature sensor mounted in the right side head between the 2 rear spark plugs, and a gear sensor on the transmission.
I'd think the temperature sensor and transmission sensor are likely still there because they take too much effort to casually remove.
If the 2 relays and the solenoid are missing all is still not lost since those parts, while not being reproduced, appear on the bay quite regularly.
If the necessary wiring for these parts has been cut out of the engine harness you'd need a new harness; but often the wiring is just left 'hanging'.
So, you might consider seeing what parts you might have and then work towards getting the system operating.
A functioning CEC system is pretty cool to see in operation.

Alan
