I would bet you that the 7468 is some sort of default value inside the module. Even the .39 sec at REV limit is probably a default value. As another poster stated, you would need to spend 25-30 seconds at any RPM level for it to register, so how can it tell you that you spent less than a half second at the REV limit?

That's what I was thinking also, but I have been informed by DTT that 7468 is the highest value recorded for maximum engine revs. There explanation was that we have probably messed a downshift and over revved the engine, possibly even higher the 7468! I'm going to ask them for a password to clear the Statistic data and keep a closer eye on it.

You have to spend 30 seconds or more at any given rev for it to be logged. The time at rev limit is measured in seconds for more accuracy

When you get the password, would you mind sharing it? I don't understand why they keep it "under lock and key".

Hmmm, they will only release this information to corporate clients after they sign a non-disclosure agreement.

In the mean time here's another chart to ponder over,


You would think that I spend most of my time in the 2-4000rpm range after looking at this. So I'll also included a sample of what I would describe as an "average ride" for me.


I like my N4 cams

Does this mean they wouldn't give it to you?

The N4 was on top above 4250 or so rpm and the N2 was on top below that engine speed. http://www.sportster.org/wp-content/...10/N2vsN41.jpg
I was thinking it sure would be nice to get variable valve timing to get both N2 low rpm power and N4 upper rpm torque.
I guess it all depends upon where your engine spends most of it's useful life.

Yep, Though I selected the N4 because its 'usefull life' is spent saving my life.
The N4 for me gives me a handfull of horses at Euro highway speeds, and allows me to get out 'o' the way of trucks in merging lanes at 80+
Oh - and its great for low gear twisties when shes wound right out..

Nzhasher,
Did you increase the compression also?
What to? Anything else changed?
It is easy to forget there are so many more outcomes when multiple variables are changed.

I understand this is dependent on the parts used but, how much power is gained by increasing the compression ratio on a 1200cc 2007 to 10.5?
