Good day
I require some help (put in your own joke here)
I was tuning today and noticed my timing was not varying. The reason for this is the “expert†tuner I had taken my car to has messed up the timing curves.
The baseline curve seems fine – ramps up from 14°at idle to 30° at 4000 rpm and then stays flat.
However my MAP curve (which adds or subtracts timing from the base line) is all positive – and by a lot! At 20lbs boost I would have been running 38° total advance. I can’t believe that is correct.
What has saved me is upon building the new engine I had set the max advance to 26°.
Does anyone here have a curve that I could start with – timing vs. boost levels?
240ztt sent me one about 2 years ago – but I can’t find it and it is not posted.
