I've been battling oscillations for a while. Really the only thing I found that helped a little was to take the D factor multiplier values from stage 0 and utilize those but it only helps a little. I'm at loss as to how to modify the other PID tables.
Please note my car is hyper sensitive to timing drops when actual load gets close to or exceeds requested load so I made the load very high and use the boost limit multiplier to control boost which helps for this phenomenon. My map is based off 4.02 stage 1+ linear throttle. Details of my car are in signature. I can upload the map if anyone wants to see it but aside from D factor multiplier all the PID related tables are the same as stage 1+ OTS. Any suggestions on what to modify to control oscillations?
