timing advance?

How do you know how much you are advancing timing (total) when you stack and nobody wants to tell you how much their module/programmer advances? And how much timing advances is safe?

Who knows?

Surely somebody knows the answer.

As I understand it, the Gen 3's have 3 injection events and I have never seen a good technical description of what the events are or when they happen. It may be that nobody really knows if that part of the code is locked up.

I've also never really seen any numbers on gen 2 timing advance and again maybe because the code is locked.

Not much help other than to confirm I have never seen numbers either.

For reference, the test they use to measure the cetane rating of fuel uses 13 degrees before TDC.

That's a start DAD. only reason I ask is everybody says don't stack a module and programmer that both advance timing, and Bully Dog advances too much etc etc. I'm wondering how they know if the info isnt available.

Thanks again.

If you have too much timing, the engine will let you know. Most of the Gen3 guys call it "timing rattle." You can also artificially increase timing by adding too much Cetane additives.

It would be interesting to know for sure. Too much timing is definitely not good long term.

Thanks, thats good to know. Also interesting because scary crazy larry supposedly increases timing past the safe point (according to their competition) but I never got any added rattle, just a whole bunch of extra power from 2800 to 3800 rpm.

Thanks for the info, Youre the man.
