Danno once mentioned there were one or more maps in the DME with spark advance and air temp as the parameters. So dont forget that Porsche is taking care of air temp too.

Easier, well, that depends on your background. Note to self - learn to program amtel microcontrollers...

NZ, jump in here, and give your 2 cents worth on its merits. Cheap insurance and costs way less than engine repairs.

As for the question, NZ runs 22psi on pump (98 RON) with around 15 degrees of advance. The timing is really something that works hand in hand with this question.

"Inlet air temp has a lot to do with knock sensitivity. In cold weather, you might be able to run 18psi on 85-87 (R+M/2) octane gas."
Same as running water injection. It is always 40 degrees out when WI is used.
