How does the power enrich spark adder work?
Say my 100kpa timing is like this:
2000 21
2200 22
2400 24
2800 25
3200 26
3600 27
4000 28
4400 29
4800 30
And my PE spark adder looks like this:
400 0
1200 0
2000 1
3200 4
4800 4
So at WOT what would my new timing be?
2000 21 +1=22
2200 22 +1=23
2400 24 +1=25
2800 25 +1=26
3200 26 +4=30
3600 27 +4=31
4000 28 +4=32
4400 29 +4=33
4800 30 +4=34
????????????
2000 21

I think It will be more like this, a smooth transaction between 1-4 deg PE adder
2000 21+1 22
2200 22+1,5 23,5
2400 24+2 26
2800 25+3 28
3200 26+4 30
3600 27+4 31
4000 28+4 32
4400 29+4 33
4800 30+4 34
A note:
I never use the adder function, I always have full timing in Main SA table...
2000 21+1 22
2200 22+1,5 23,5
2400 24+2 26
2800 25+3 28
3200 26+4 30
3600 27+4 31
4000 28+4 32
4400 29+4 33
4800 30+4 34
