Thread: Standalone post-start enrichment

To the standalone users: What settings are you using for post-start enrichment?

Here are mine, the EMS I'm using (Link G4) expresses it as a percentage of the main fuel table. When it's stone cold (30deg-) it's fine, when it's hot (70deg+) it's fine, but in between the post-start mixtures seem to be a bit off.



The symptom is that once the engine fires (and I never, ever have to crank it for more than 3sec to do so), the revs will reluctantly pick up and hold at about 500-600rpm until 6-10sec afterward, when the post-start enrichment has decayed sufficiently.

Honestly the easiest thing to do is going to be taking away a good chuck of fuel around that temperature and see what happens. Then add a good chuck of fuel and compare.
After 50 or 60 degrees C you might be able to do with around 1 second decay time instead of 12-10 seconds. It's worth a shot.

That's exactly what I ended up doing:



Post-start enrichment is now 30-50% of what it was previously, warm-up enrichment is now 50% of what it was, and crank enrichment is 50-75% of what it was. The engine's much happier when it's cold, and my day-to-day gas mileage has improved by ~20%

Excellent.
It really is that easy folks. =]
