So as you all have read, I pulled the trigger on a 996 GT3 with 9,000 miles 2 owner car. When the owner did a DME readout on the car, which was done at a Porsche Dealership, it read:
overspeed range 1: 0
overspeed range 2: 0
overspeed range 3: 0

That looks suspicious to me. I can of course cancel the deal, as I still have not mailed the check, but I thought the 996 GT3 is suppose to have range 1 and 2, not 3?

Yea, that's not right. Ask for a screenshot of the PIWIS readout so you know it's legit.

Yup, only 2 ranges to choose from. As stated prior, ask them to text you a pic of the DME on the PIWIS. You will know it's your car as the VIN shows on the screen simultaneously. I had that done when I bought mine. Easy...

If it turns out the car actually has NIL over revs in any range, it really is a virgin as 996 GT3s register range 1s like nobody's business.

I got it all straightened out. It has number of

ignitions range 1 --
ignitions range 2 717 99.9h

operating hours count 251.1 hrs

The first DME i got was from a different car, the dealer made that mistake.

How does it have Range 2 without Range 1? That seems sketchy...

Range 2 is bad, bad, bad

It seems this DME records the reverse, which is a known issue.

I've read that this "reversal" can happen with certain cars. You are likely right as there are no Type 1's, which would be odd if there are type 2's. Hopefully someone with precise knowledge can chime in. Regardless, even if Type 2, 150 hours have passed since these over revs were reported. I'll bet they are type 1's though.

just wondering if you sorted this out. i am not an expert but never heard of the reversal. as a test you could accelerate to the rev limiter for a second and see if the numbers change and where they change, range 1 or 2.

i know your post is a few months old but you may want to look at the number of program operations performed to the dme. you will need durametric, pst2 or piwiz to see this. if you see 1 or more program operations you know that someone updated the flash and perhaps altered these values. i don't how anyone could do this with durametric or a pst2 but i am not familiar with piwiz.
