MAT Temp Corrections, an example
While still a Work In Progress, here's something to look at.
This is from the 58 code, and what I've been working on.
I first got the main VE table real close at a MAT of 140-160dF
then worked upwards, with elevated MATs, and made changes here to maintain a BL of about 129.
Then dropped the C/L enable to get a BL correction as early as possible. And worked on the lower temps.. The slide the whole table over to get things somewhat smoother.
; Base Pulse Inverse Air Temp vs MAT
FCB 16
FCB 175 ;148 ; Hot
FCB 165 ;149 ; 136
FCB 155 ;151 ; 107
FCB 149 ;143 ; 91
FCB 147 ;144 ; 80
FCB 147 ; 71
FCB 149 ; 63
FCB 153 ; 56
FCB 165 ;161 ; 49
FCB 169 ; 43
FCB 175 ;170 ; 37
FCB 177 ;172 ; 30
FCB 179 ;175 ; 23
FCB 185 ;177 ; 15
FCB 192 ;179 ; 6
FCB 192 ;182 ; -8
FCB 192 ; Cold
What I couldn't gather on the car, I connected the dots with the ecm bench.
Needless to say I've broken even on all 4 of the benches I have ages ago.
