so yest please :)

best regards
1b15 trans temp 0.75*x-40

1bd oil temp 0.8*x-40

fan1
change
86ae-[01bd->1b15]

tune
2657 x*25 rpm threshold for fan1
2658 timer for rpm threshold
2655 threshold on lower rpm 9c 40 on
2654 threshold on higher rpm 9c 40 off
2656 hysteresis

fan2
change
8779-[01bd->1b15]

tune
265a fan2 threshold if rpm lower
2659 fan2 threshold if rpm higher
2656 hysteresis

some initial findings.

Some tuning of oil thresholds will be needed. You can check some vette bins for data comparison.
