Timing

[Magard]

I wouldn’t think retarded injection timing would hurt. Egt will be high. Turbo boost from my playing around seems to go down with slightly retarded timing. Advanced timing creates water and oil temperature. Cooler egt. Slightly advanced timing seems to run really smooth but creates slightly higher water and oil temperature. Advanced timing gets smooth under slight power but violent feeling under power and pulling power seems to go down. When right the 2250 seems clunky or chuggy sounding but smooth in the gearshift. In a 2250 this can go one way or the other in a degree or less. Meaning you start really splitting hairs to get it right. 871 isn’t this sensitive but should still have similar characteristics. I would think a degree in soi one way or the other should be noticeable if it’s close to right.
