What are open loop fuel tables and what can they do?

They determine the Open Loop Air Fuel Ratio commanded before going into closed loop. Exception is Power Enrichment fuel: If PE fuel is richer it is used, if OLAFR is richer, it will be used.

is there any open loop timing tables? Im doing some Open loop fuel tuning and im seeing really odd timing amounts(very low)

ECT (coolant) Spark Base sounds like what you are looking for.

I've got that table zeroed out so that isn't it.

I think Bill said once that open loop will put you onto the Low Octane table. So if you are tuning open loop, copy the High Octane table to the Low Octane table. (so they are both the values of the HIgh Octane table.

thank you for that clear answer!!!! i searched for 2 hours for that answer..which one would take the lead over the other.



ALSO, CAN WE MAKE THIS TOPIC A STICKY????? (VERY HELPFULL!)

If my cranking Commanded AFR Hi Rez is ~8.6 how much would I need to adjust this table to fix that? I don't want to shoot back and forth with this.
