E2567 Equivalence Ratio Limit - Explanation?

[2006Cummins]

Can someone please explain the E2567 Equivalence Ratio Limit for me? I see the description states" that "0" is "clean" and "3" is "smokey. But, I don't see exactly how this table interacts with the other tables. Thanks.

It's a little bit of a mystery table for sure. It's just a calculated value the ECM keeps track of to ensure the commanded fuel won't cause smoke. We haven't had much feedback on it's overall functionality on the end injection results.

Every time I adjusted the value higher than 2 in my AW calibration file the truck felt bogged down. I'll have to see what happens now that I've gone back to my AV file.

EDIT: Also the truck seemed to smoke less with the number above 2.

I haven't had any luck controlling smoke with this table at all. I am running ~200hp sticks, and an S466 so thats a challenge either way, but I have dialed it in now to where smoke is almost non existent. Loving the tuning capabilities.

Thanks for the feedback. So, I should probably just leave it alone for now? I'm curious to see if anyone has spent much time playing with it.

On my street tune, I do use VERY low numbers, which theoretically should limit smoke if the ECM was calculating correctly. But, the ECM does not know about the injectors being so much bigger. Id say you would have more luck with this table if you had stock(ish) injectors.

I set the entire graph to two, then set the entire graph to 0.1. I saw no difference with smoke at all.
