can someone help tell me if this is good or bad?

Range 1

2960 848.9 h

Number of ignitions

Range 2

304 848.9h

This is the DME data i have from PPI today. I am planning on buying the car tommorow.

Thanks

What year is the car and how much mileage?

You also need the value for the "operating hours counter".

The operating hours of the engine (which might be in your case 848.9 hours) have a correlation to the mileage on the car which might give you an indication of whether the odometer reading is considered "normal" or "suspect".

This should be compared to the mileage to see if the number makes sense. If you divide the odometer mileage by the operating hours you will have an average MPH.

A "normal" average MPH will be between 25 and 50 MPH, so it helps to know in what setting most of the driving was done (i.e., highway or city traffic).

This vehicle shows range 1 as "2960 848.9 h" which means the vehicle has used the rev-limiter for 2,960 ignitions, the last time being at 848.9 hours. So in other words, the engine was red-lined often and the last time was very recent if we assume the engine only has 848.9 hours.

It also shows Range 2 as "304 848.9h" which means the vehicle exceeded the redline 304 times. Not a good sign IMHO.

v996tt:

The number is the number of ignitions in each of the two ranges.

The hour refers to the last operating hour that the respective range occured in.

V996tt, there are a ton of 996TTs for sale. Don't feel pressured to buy "this one" if that is what you decide to do. Be patient. And ask all of the right questions, just like you have done. Good job.

You will find the right car. The hunting is the most fun part.

Here is a link for your info Type1-2 over rev. Look at Wross996TT links. Very good info but people don't agree on type 2 definition...Just to give you an idea I purchase my car without interrogating the ECU and look what I have found after purchasing the Durametric software:

Ouch : type 1 65535/1248 h (65535 which is the highest number the ECU will register. It stop at this number)

type 2 67 / 1197h

I touch wood, the car is running strong and the oil consumption is normal....

Thanks everyone. I had to pass on that car for other reasons as well. I am looking at other car next week so hopefully will work out.
