After tuning with success my new alpha/n table, it seems that I have a light increase of AFRs when the temperature drops. So i need to adjust IAT correction.
I found 5 tables that I think are IAT related (descriptor D0).

- The first table in 8x5 is also related with C9 descriptor but I dont know what it is. The correction is certainly for fueling, the values seems logical for an IAT correction, as the table enrichs when the temperature drops. The enrichment decreases when the value of the descriptor "C9".
-For the other tables the values stay unchanged or rises with IAT, except for the 4x1 table but this one is never traced by the Ostrich. Maybe there is one for ignition timing, like "adding retard" or something like this?
So I think the 8x5 table is the good one to tune but I will have to extedn the IAT scale like for the alpha n table because I can see changes in AFR with less than 30°C variation.
If someone has some advice about that, he's welcome!
