Hi,
I cannot get my car to rev above 4000 rpm when in PARK with my A6 transmission, is this by design to keep you from blowing up your motor under no load? When driving yes I can get to 6,500 rpm and the car doe go bat out of hell. I had several people ask to rev my motor and that is when I noticed it sitting still it just maxes out at 4,000 RPM?

A rev. limiter in park is so cool! If this is actually the case, then they really did code in a bunch of very interesting features.

How high do you want it to go? Or is this a reason I don't buy used cars.

Slip it into neutral, place left foot on brake (or engage the parking brake) and rev to redline.

It may also be dependent on driving mode. Try Track Mode.

Nothing beyond redline?
Good point, Boomer. That pesky rev limiter should be disabled first, then rev the engine to 8500 RPM a couple of times.

The flames shooting out the tailpipes (and the little pieces of exhaust valves rattling on the ground) are sure to impress the ladies.

First of all according to your info you only have 146 miles on your car. The Stingray has an break in period (up to 500 miles) red line at around 4000 rpm. Second, if you have more than 500 miles, the temperature of the engine will determine the initial red line below the full engine redline. If the car is cold, you will see the red line is again around 4000 rpm and as the engine temperature rises it moves from 4000 rpm to eventually max when the engine is at operating proper temperature. Hence c. 4000 at park, and full red line when out on the road. Here is a pre 500 miles shot and post 500 miles of the red line

I am enthralled with the 20,500 rpm on the Z06 supercharger.

:eek:Agree! With comments from some recommending "drive it like you stole it" for break-in; I thought the procedure recommend for our new SUV was very interesting. "Do not exceed 4500 rpm for the first 1200 miles!" The engine has a 7000 rpm red line! It’s a BMW 5X sDrive 35i, all-wheel drive SUV. The 3 liter (182 cid) twin turbo inline 6 has double overhead cams with individual intake and exhaust continuously variable valve timing for the 4 valves per cylinder. It has 300 hp and in a C&D test achieved a 0 to 60 time of 6.0 seconds, not bad for a 4800 lb car!
I think the Stingray's colored warning rings during break-in and after until the engine is warm is a great feature. It doesn't force you to follow but it's a good idea!

The PCM will not allow full WOT until the water temps are normal and the PCM goes into closed loop

Park or neutral is tuned within the PCM to cut off at 4,000 RPMs for multi reasons
but one is if the crank position sensor needs to be relearned/sync'd to PCM the trigger needs to be lower so 4,000 RPMs is used as you would not want to do that relearn at 6,600 RPMs while parked.

Great info. Nice to know the Control Module is smart enough to keep some out of trouble! :eek:

It's good to see we can still go at 6600 RPM in reverse - what a relief. :rolleyes:

So, you put in "R" for race eh? A bit of road rage Mobius? Carefull around those kinds of trucks, they can really smell and if you break it there, then you get the odor of the month prize. OH, by the by, GM monitors this site for reasons not to honour warrantees. Just kidding. I think.

STUNG:rolleyes:

Thanks for like, Mobius. I was just having fun at your expense. Hope all works out for you and you did not do any damage to the engine. That can really piss you off if you weren't already.

STUNG........:cool:
