Application Specific - How I make RB26 timing maps

After one of our viewers asked the question "How do you make a timing map for an RB26" I thought I'd come back to the subject. The theory behind it will apply to any car, naturally aspirated/nitrous/turbo/supercharged. I have covered the subject in detail but a fresh perspective and applied lesson makes sense. next week is V8 and nitrous 😁
