Hey guys, wondering if anyone can help, this is on a BAM engine. What i am trying to achieve is to have the cars fueling controlled by LAMFA the majority of the time, then if the EGT reaches a certain point, have it controlled by KFLBTS. This is what these tables look like stock:  and this is what i have changed them to: (LAMFA targets best spool and best power)  tables on the right havent been changed from stock Will it work like this or do i need to change any other tables? What is KFDLBTS and does it supersede KFLBTS? Thanks |

Both Dlbts maps to zero
Stabgm to zero
Tabgbts to 860c
Will use lamfa most of time, Will switch to bts map when around 5500-6000 on a 4th run dependant of your egts, then obviously stay there when driving hard through 5th/6th.

Factor should be 0. Use the Wiki for the calculation so you can understand.

thanks guys, how does this look:  I've enriched the last value in LAMFA as i was getting 5.3 timing pull on a couple of cylinders after 6000rpm 3rd gear, or could i use these maps instead to enrich when timing is pulled?  Just realised my KFLAMKR columns arent defined correctly, should be rpm |

i never will understand why people set 0 bts maps, it will be easy to calculate desired afr but bts factors help to protect engine for a disaster if something goes wrong, (if engine have very high egt on low rpm for example it is extrange but could happend)
On the other hand why used lamfa always as fuelling? as i have test car is faster with higher afrs... 0,95 like on stock file.
i like let lamfa stock and when temperature rising get fuelling via bts (with an afr of 0,85) and let Stabgm for component protection with reacher lambdas.

Just realised my KFLAMKR columns arent defined correctly, should be rpm I'd run lamfa around 0.8 at 6k onwards 0.82 from 4000 0.85 from 2000-3000 Smooth between 3000-4000 Use the 84% row of lamfa enrich it slightly etc. Run bts down about 2-3points lower than lamfa to around 0.78 top end. You'll gain power by getting your cf's to zero. Have you turned off the armd so timing is smoother? |

Read the headings of the tables and you'll see why that's bad.

If tabgbts....860c and Actual egt over 860c = switch from lamfa to klfbts if values in klfbts are lower than lamfa.
