This weekend, my car seemed to hesitate/surge a bit on the freeway (on a really hot day) so I took the car into the dealership. Unfortunately, they couldn't find anything wrong with the vehicle, and I'm chalking it up to bad fuel (the car's been running fine since).

In any case, as a result of this misadventure, I got a DME printout from the dealership. This printout included a list entitled "Number of Ignitions" and included Ranges 1 through 6. Now, my understanding was that range 1 usually meant the number of times the rev-limiter had been hit, and range 2 meant the number of ignitions where the rev-limiter had been exceeded, but have no clue what ranges 3-6 are. Perhaps the 997 printout is different from those of previous 911s? Any insight into this would be very welcome.

With the 997 there are now 6 ranges. The 996 had 2.

So which of the six ranges are equivalent to the old "range 1" and "range 2"?

Don't know because I never seen published data on the limits for the old range 1 and 2, just a lot of internet speculation. I use to say 1 was high and 2 was very high.

But there is a Porsche memo on the new range 1-6.

Thanks for the response -- I had an opportunity to speak with someone at my dealership who explained that ranges 1-4 were fine, whereas ranges 5-6 were a problem. That's as much detail as I can seem to get on this issue!

Someone on Rennlist got this Porsche memo. If you enlarge it you can see the Range 1-6 rpm numbers.

Range 1 is 7,300 rpm to 7,500 rpm.

Skipping Range 2-5.

Range 6 is is 9,501 rpm to 11,00 rpm "at which time I reckon she'll pretty much blow up." :rolleyes:

Fuel shut off is the rev limiter which comes on at 7,300 rpm. So if someone got an engine into Range 6 they did something bad, like miss a down shift.

how does the x51 powerkit affect the ranges?

fuel cut-off is not until after 7500 rpm.
