Catheating OFF disables coldstart completely, the other is still ON, but you pick the RPM target.
Thanks Halim, so would I be right in saying I could get the initial startup 'roar' by leaving cold start on but reducing the aftermath noise by setting the RPM limit to 750 (for example). Or, would this prevent the engine reving past 750 upon startup and thus preventing the roar?

I would test myself but currently doing other diagnostics
