M103 - What happens when the ignition timing advance increases at 3,200 RMP?

[Michael K]

The M103 in our 300 SL REALLY, REALLY comes alive at about 3,500 RPM. It’s like a power switch goes on, you’re pushed into the seat, and bam it’s at the maximum engine speed in seconds. Below 3,500 RMP power is adequate but subdued. Over 3,500 she’s a raucous beast. I found the table shown below and noticed, in the ignition system section, the 3,200 RPM number. This got me thinking about several questions.


1 - What happens when the ignition timing advance increases at 3,200 RMP?
2 – Is it normal for the power to increase so dramatically?
2 – What is the EZL ignition system (see picture) on the European version M103?
4 – Is my EZL set correctly to run on the premium fuel she drinks?
