adjust the "TIM" is very convenient!
but the setting on the old "ENT" I now do not understand. (Z32_FOR_RB25DET_41P03_MT_v3)
I changed the MAF on the z32, now it turns 80TP = 5 volts MAF?
To use the the entire width of the fuel card I just need to turn down the TP?


this figure boost of 0.5 bar (MAF z32), and is used only half of the map, in the past was a different logic.
in the past after conversion Mafa load TP has remained unchanged for the stock boost

or have just a glitch in the program?

You will need to increase K constant to move TP further
(TP = MAF lookup / RPM x K)

Once increasing K constant, it will add more fuel, so reduce TIM to get fueling back to normal.

This is covered in our software tuning guides and documentation :D

tuning the firmware with the "TIM" I understand)))
in my firmware is not Tim.
I have an old firmware Z32_FOR_RB25DET_41P03_MT_v3
the transition to MAF z32 I remove the check mark "half" and "GTR ECU"

Yes remove this. That tickbox is a bug which I need to fix from last verison, but does not actually half (even though tickbox is displayed)

Okay if you have no TIM, you need to change your TP scaling for fuel and timing maps so last column about value of 60 so it uses whole map
