After reading that last night I immediately pulled timing from the higher load part of the table.

This came from a thread on the Innovate Motorsports forums. This is moderated by Klaus who is very well versed in engine tuning via the WBO2s.

There is plenty of info there too.

And good tech articles here too.

Very good article, now if I stop seeing posts that spark plugs cause detonation I will be happy. he even describes a crude ionization preignition detector, brilliant!!

you would be surprised at how many otherwise very smart people are totally ignorance of this topic in certain auto manufacturing companies, and they blame cetain spark plug manufacturing companies for piston scuff amid 1000's of other det. related issues.

the few non-essential statements he made that contradict things I have observed in real engines are so few they are not worth mentioning. I definitely will pass this on!

Here's another link that has loads of info concerning timing and the newer designed pentroof 4 valve motors.
