Sami pointed out that if you use a 1.1.23 Megatune with 1.1.24 and up firmware your PW will not show the right value. The value was 8bits in 1.1.23 and it's 16 bits in 1.1.24.
I have also seen that you use 16X14 tables, that is not recommended. It's only used in Finland and getting help outside finland will be hard. 12X12 is more then enough with the type of fuelcalculation we use. It's different with more primitive fuel calculations that is used by many other systems, or when you use Alpha-N which is always equally primitive.
