He guys,

Currently i am in the process of assemblying S54 ITB's to my M52, which has the S54 TPS.

the S54 TPS goes from 0%-68,3%
My old M52 TPS goes from 13,3%-88,2%
A lot of TPS related maps in MS41 range from 0%.

My first question is:
Does the ECU do any calculation to make the 13,3% a 0% for the use in the TPS related maps?

Second question is:
If so, is this something I can change?

If the ECU just never get the input of 0% TPS, and the maps will always be in the 13,3% or above part, that would be good to know too.
