Operating Hours Counter and Ignitions (Range 1)

:welcome:

Please do not support the China knock off cables - you support of them will put Durametric out of business and ruin a good product that is one of a kind.

If you do a search here you will see ignition ranges have been discussed many many time.

You will also see that range 1 is - rev limiter controlled over revs and that they mean very little.

On the 9x7 series cars you really only need to be concerned with number in ranges 3 and above.

Thanks for the answer. What I am worried about is that the I get a lower value for the operating hours then for the Ignitions (Range 1). It differs more then a 1000 hours. As I see it some one has changed the operating hours to a lower value, and offcourse the odometer.

I read that one could check the airbag operating hours as well, I´ll try that later on today.

If the engine has been replaced by a dealer then the operating hours were likely reset at that time.

I don´t think that the engine has been replaced. Is possible that the operating hours has been tampered with? Is it even possible? The odometer says 78000 km and the operation hours 1896. Can you see more info with the real PIWIS? If so, then I should have a Porsche Center to check the car.

I read that if the ignition key is left in the ignition lock then the airbag hours will continue to go. Is this correct? Is it the same with the hours that are listed after Ignitions Range, does it continue to as well? If so, then this could be the reason for the difference in hours.

That is correct the airbag circuit is activated whenever the key is in the ignition.

The airbag circuit counter and the DME engine counter are separate counters - but in real life they should show very similar hours.

The range errors are reported using the DME counter.

Hi,

I just bought a Boxster S from 2005 and I checked the ECU info and saw that the operating hours are 1869 but when I look at the Ignitions (Range 1) it says 65535 / 2965h. Can that really be correct? I used a china piwis cable and a old Durametic, ver 3.015 I think.

Hope to get some helpful answers.

2^16=65536 and yours says 65535 with the last one 2965h ago.

I believe DME memory is 16-bit.... so your DME in that memory address has "1111111111111111" (16 "1"s). Quite possibly the result of you using fake/junk equipment or old software. You might have saved a few dollars now but it's likely going to cost you in the long-run with garbage readings like this.

Hi, I understand that. I honestly didn´t know that the China cable would be a copy since it came with an outdated version of the program. I thought that It just was an old, but fully working, version of a outdated product. Durametric doesn´t even have that version of the cable or program anymore. Since I didn´t need all the functions that a new cable, read original cable, includes I bought this one. For me the cable was just a dumb cable not an electronic devise that had build in intelligence. Was I naive, ohh ya!!
