Been going trough parameters on calterm I see Chi tables ,alpha tables and fuel tables since there are multiple chi tables does anybody know what each of them are for if you have any info I'll gladly appreciate it tia

Each Chi mode are for different engine operating modes I.E SCR warm-up, Parked regen, Egr on mode, Egr off mode etc.

Theres 5 mains vector tables which decides what engine operating mode it will be in. Ill attach a screen file with those tables.

Alpha0 - Warmup/Oil temp Prot
Alpha1 - Steady state
Chi-2 High altitude (engine protection)
Chi-3 EGR derate/other derate
Chi-4 Non EGR mode Prot
Chi-5 Cold ambient mode
Chi-6 SCR Eng Prot 
Chi-7 EGR Prot
