logalini, for clarification, your 10:1 equivalent pressure grid is essentially saying is "the following pressures under the following compression ratios, are the equivalent of running x psig in a 10:1 engine"?

If im understanding you right then yes.


If you look at the 10:1 equivalent pressure map.

Under 8.5:1 compression ratio the last number is 14.3 psi.

Now look at the psig column. 19.432 psi in a 8.5:1 engine is the equivalent chamber pressure of running 14.3128 psi on a renesis.

Or a 19.432 psi on a 9:1 rew is equivalent to 16.0192 psi on a renesis.

There is no direct conversion.
Load does not equal PSI
Depending on the setup a different PSI may reach a calculated load of 200% .
This can also be fudged depending on how the tables are setup

For tuning purposes you can roughly correlate 14-15psi to 200% . In a good system that's going to be close to actual in a bad system it isn't but still better to scale for that as it helps keep the tune safe.

This is what I run on 100RON/E10 blend, up to 185-190% load @ 12 psi.
