Name: Desired Torque

Description:

The desired tourque table in it's simplest form is your boost controller. The tourque measurement is in Newton/Meters. One Nm equals .737561 foot pounds of torque. The desired torque is converted to a pressure ratio using the pressure ratio table in the speed density section of the code. It then calculates the error between actual flow and desired flow. Once the PCM has the error, it uses the wastegate duty cycle table to adjust for the correct airflow.

Use:

The y axis of the table is throttle voltage. the largest voltage is set at 2.8 volts which the pcm sees as full throttle. So this makes the last row of the table "WOT boost". The lesser rows are for "part throttle boost". The idea is to change the last row up or down by a cetain percentage until you get the peak boost you are looking for. You then adjust the rest of the values in the last row to even out the boost. The wastegate adaptave high and low limits will help smooth the boost curve if set to a larger amount(15.0 or higher) Thanks go to OJCool, Mana4real, and Moreause for figuring this out.
