Durametric Ignitions R1 and R2 Counters

[blundgren77]

I have an '01 Boxster I bought about 4 weeks ago. After buying and getting my durametric fired up, I noticed the Range 1 and Range 2 ignitions counters. My car has 1750 hours on it, with around 13000 R1 ignitions (last one over 100 hours ago, before I got it) and it has 2 ignitions in the R2 range, that were counted only 100 hours after the car was new.

My question is, how many is too many? If I understand it right, The R1's are the number of ignitions where the rev-limiter fired at red-line. The R2's are ignitions are over red-line. The R2's are obviously bad, but what about R1's? If the rev limited did it's job, is that number anything to be worried about?

And out of curiosity, how does one get over red line in the first place, when the engine has a rev limiter to prevent it? Bad downshift?

Thanks!

Neither are anything to worry about.

I am not sure how accurate the R 1's are as my car has some 57,000 R-1's and no r-2 and I always shift closer to 7,000 rather than 7,200. The revlimiter may be set wrong
