OK, great work. Here's the map pack with the most recent torque maps, dynamic KR fueling, and nls/als + misc code-words discussed in recent months. [obviously an assembly modified bin is required to have the nls/als] [old news]

lamfawkr_w = 1-(1 - (KFLAMKRL + DLAMTANS) * KFLAMKR)
Ok, thats retarded. Using my basic algebra I skills, 1-(1-x) = x So isn't this equivalent to (KFLAMKRL+DLAMTANS) * KFLAMKR? [edited to fix stupid algebra error  ] |

Using my basic algebra I skills,
1-(1-x) = 1 + x
So isn't this equivalent to
1 + (KFLAMKRL+DLAMTANS) * KFLAMKR
There's obviously a sign missing some place, because aren't both KFLAMKRL and KFLAMKR positive?
Given ... KFLAMKRL = 11.7 DLAMTANS = 0 KFLAMKR = 1 1 - (1- ((11.7 + 0) * 1)) 1 - (1 - 11.7) 1 - (-10.7) 11.7 |

that makes no sense  KFLAMKRL is in delta lambda not delta AFR |

LAMFAWKR, did anyone else find this variable funny?

Inevitable happened today. After getting a tank of 93 octane fuel I proceed to floor it on the highway and all of the sudden I dip to 10.3:1 AFR during all out WOT... that's with meth squirting...
On a normal car it wouldn't be anything alarming unless of course this would be a result of bad misfires, but on my car it is indicative of severe KR fueling intervention. I quickly logged the car and I clock -8.5 corrections which is what I would normally get if I run out of meth on 93, but meth is squirting as verified by running pump on manual and the fact that the level dropped during next run.
This only means that either I dozed off and pumped 87 octane or something, not likely, or the assholes at gas station are cheating badly on fuel.
Conclusion is that if I had fixed BTS fueling I would had much heavier corrections at a target AFR with possibility of maxxing them out altogether and pinging he engine..

Can you clarify the above statement? I don't understand what you mean by "fixed" BTS. Scary shit though... |

KR enrichens more and more the higher correction factors are used.
BTS is effectively fixed in that respect. You'll run the same AFR regardless of knock.

Personally, I don't enrich via KFLAMKRL beyond my zero row until ~-8 because of DZWWL's influence. On a typical pull, DZWWL will offset dzlamfaw by -1.5 to -3. BTS is effectively fixed in that respect. You'll run the same AFR regardless of knock.
Only true if you have disabled LAMBTSZW via DLBTS and KFFDLBTS. |

I thought dzwwl typically offets dzlamfaw the OTHER direction (hence setting CWLAMFAW bit 0 to 0) |

Any suggestions for wording describing that for the s4wiki?
