Setting target AFR for Startup

[auspeed]

Is there a set way to control the relationship between what is shown on startup for AFRATIO_DMA & what value i enter into E38.INVLVTMP_DMA in B0143?
car is e38 LS3 auto

I have gotten to the point that I can predict when the car will start fine based on when the AFRATIO_DMA is between 8.8 & 9.45 with key on. any higher afr value and it stumbles. I have also noticed logging the pid E38.INVLVTMP_DMA that it goes from 147 to 225 in 1 sec as soon as the engine is running, I dont recall that being normal behaviour?

If i let the car site for 1-2 mins the E38.INVLVTMP_DMA lowers enough to bring AFRATIO_DMA to within range.

for example Can i set a target of 9.2 afr for 85 degree coolant for the entire row to remove the variance of E38.INVLVTMP_DMA values ?

I'm looking thru a few E38 files to see if I can figure this out (or more accurately, if something jumps out at me)...

Setting B0143 to target an afr value still doesn't lock the target AFR. I'm finding manipulating the below tables still doesn't give the desired result.
The full equation is - B0143 + (B0144 - B0143 x B0145) x B0146 x B0148 = Final Commanded Fuel Ratio


Is it normal for E38.INVLVTMP_DMA to read 135 on crank then jump straight to 226 1.5 secs later and just stay there???
