Add Boost Pressure Actual, TIP Desired, TIP Actual, WGDC Actual, WG Canister Pressure, and WGDC Y-COP Relative to your logging profile. These are the primary components to properly tune the wastegate PID system in this configuration. If needed remove other unused monitors from your logging profile to make room.
The first thing you'll need to do is collect a datalog of your vehicle with these monitors included. We recommend tuning the car in 4th gear for best overall results. Our recommended recording window is from 2000-6500rpm.* This will provide an ample sweep of the TIP Desired and TIP Actual to begin coarse modification to the WG Canister Pressure Desired (FF) 5-Way table.
Once the data is collected, review the log for problem areas in need of adjustment. Find the cell that matches, and highlight adjacent cells as well if needed (the ECU will "blend" several cells to get final values). Make small incremental changes to the base table then re-flash and re-log. The goal is to find a happy medium of the WGDC Base values and WG Canister Pressure Desired (FF) 5-Way values such that the desired boost pressures are achieved in all conditions!
Additionally, there are upper and lower ceilings for the final calculation of the PID I-Term which can be used to loosen or tighten the reigns of the system if necessary. These are found in the Integral folder and are labeled PID I-Term Max. and PID I-Term Min..
