I have been noticing that my load tables on the High Octane table start at 10 and move in sections of 10 like this:
10 20 30 40 50 60 70 80 90 100 110 120 130 140 150 160 170 180 190 200 210 220 240 260 280 300

A couple of maps I have been looking at from other peoples tables are like this
10 20 30 40 50 65 85 100 120 140 160 180 200 220 240 260 280 315

I have looked and looked but I can’t find any info on why. Can anyone enlighten me please?

 

Most likely explanation is that these people have rescaled their load ranges to suit the loads their cars are hitting.

and the VIII has a different map configuration than the IX

 

Exactly. When you start to modify your car, expecially with flow modfications, your loads get higher and higher.

For example, stock on my car was hitting in the 240-260 range. With my new injectors, I could run more boost, and would see loads sometimes at 315. Rescaling your loads on the maps allow your ecu to correctly use timing/fuel values (assuming your tune is OK) when it hits loads that high.
