I am getting ready to take my car (C5) in for inspection. Because I have been working on it and have disconnected the battery numerous times the readiness tests need to run. I am doing some dyno tuning on Monday and could run it then. I am thinking the TCS will trip because the rear wheels will be spinning while the front wheels will be stationary. Will the test run with TCS turned off? Any ideas?

Can you do a typcial drive cycle on the dyno in a timely fashion...?

Cold Start, coolant temperature less than 50°C (122°F).
Idle 2.5 minutes in Drive (Auto) Neutral (Man), A/C and rear defogger ON.
A/C off, accelerate to 90 km/h (55 mph), 1/2 throttle.
3 minutes of Steady State - Cruise at 90 km/h (55 mph).
Clutch engaged (Man), no braking, decelerate to 32 km/h (20 mph).
Accelerate to 90-97 km/h (55-60 mph), 3/4 throttle.
5 minutes of Steady State Cruise at 90-97 km/h (55-60 mph).
Decelerate, no braking.

Yes, the only issue may be coolant less than 122 degrees F. I can run the car according to the test requirements. I was curious about TCS tripping if left on, or if the test can run with TCS turned off.

The instructions don't say turn Traction Control System on, or to not turn it off, so it must be okay.

It may be easier to just do several drive cycles on the street from a cold start.

Yeah. Here in NJ it's so crowded I had to go out 4 times just to get to 55 for 2 mins, then back to 20mph and back to 55. BTW, try doing 20 to 55mph with 75% throttle with 4:10's and 460rwhp. It's hard, at least for me. :)
