Aaah, this one has given troubles as well... from your cold idle thread (read it 1,000 times) I changed these values to 94170015 values (I'm on 96533706). The 94170015 values seemed bigger, whereas Mrfreds description in the advanced fuel thread suggests smaller values.

While tuning for SD running rich, (idle at 10-11 AFR) made for fantastic driving manors when when cold.

Now that AFRs are in check, cold drive-abillity sucks, as in it goes 16-18 AFR lean and dies with any throttle before it warms up, then it's fine.... Thus my interest in this table, I would really like to understand what it does. I have fixed all the other EGR related stuff in the cold idle threads.

 

Never mind.

I looked into my 9653 and 9417 roms....yes the 9653 version is much lower.

Maybe something to consider is that e85 requires more fuel input so higher values may not be so bad.

 

To answer the OP's question, because this map is (presumably) to adjust fuel as the car warms up it would be unique to that function. Your main fuel maps should be tuned at running temp and your closed loop trims should be tight at 14.7 (at temp).

To get it to drive nicely cold on SD with big injectors and e85, I'm looking at this table to toss in more fuel to prevent the lean tip-in/ bog condition.


Do bigger numbers increase fuel, or reduce fuel? What are "units"? Can anyone confirm the definition is correct?

Thanks

 

Bump for the above questions. Thanks! (table pictured in post 16)
