But there seems to be some timedelay on KFLBTS also?
There is also a factor flbts_w which influences enrichment. It has initial value 0 and then raises to 1 with delay TVLBTS and a speed constant ZLBTS. See LAMBTSENABLE section in FR. It's similar to how LAMFA is delayed by TLAFA and raised by ZKLAMFAW. Additionally, if you have KFFDLBTS enabled i would also look at dlambts_w and its speed constant ZDLBTS (section LAMBTSZW). |

The delay is FBSTABGM. It disables KFLBTS until 850C (or thereabouts, I am not looking at your file)
Hello, This seems to have solved the issue, I put all 1 in the FBSTABGM and now I get quite close to requested labda also in "fast" transients. Should be more safe for the engine now and maybe it will even stay in one piece. t was disabled up to 850 deg, reading the FR better would in hindsight have been well spent minutes. BR. Kenneth |

Anyone have the address for LAMFA in C box thought i had it but all the numbers are completly wrong, want to try with LAMFA and see how it compares to BTS

Anyone have the address for LAMFA in C box SW:350093 1B8D0 Rescale %PED axis if you want LAMFA to be active. |

Why are you using C box? |

Beacuse i have C box on my S4 and want to use that, i have a D box that i was going to flash a M box .bin to but having issues with that but id rather put the effort in and use the C box,

If you can't find maps yourself, you are better off using M-box... You're not saving any time/effort staying on C box. |

Great thread.. Been reading 2 times now to understand. What about E85? This seems to only implies for pump gas ( i.e. 91 -93) and not E85 since it doesnt knock the same way. As i understand it fueling via BTS is the simplest way to go i running BT + E85 setup. There will be no engine protection though.. but thats life when you running a very modifyed car isnt it?   |

How doer KR fueling handle that? E85 Doesnt knock as Gas? |

Are you asking if the KR mechanism detects E85 knock correctly? |

Well nyet if its possible to detect knock on E85 and there is a mechanism for that it would be greate to learn more about.  I am between two options then.. On one hand it seems more simpler to go with BTS fueling for my project. On the other hand it seems more "Correct and optimal" to go with the factory type of tuning for fuel.. Concerning being more safe with BTS as a "safety net" I have my own built external kind of safety system. Im running an arduino based boost controller with WBO, EGT, IAT that would cut boost and warn me if temps go up. What path would you go nyet?.. |

The first column in KFLAMKRL will be used when wkrma <= the axis value ( absence of KR). Six load datapoints coupled with 6x6 KFLAMKR is effective.
Assuming I understand what you're saying...

As i understand it KFLAMKRL (fuel@knock) = Enrichment during ignition angle retardation. Retardation occurs when knock.. E85 (not the same knock caracteristics as pump gas) = U dont get enrichment = Problem |
