Hi!,

Can anyone help me with this, i cant work out why my base WGDC is spiking like crazy under partial throttle and making PID go crazy as well. You can hear it in the car:


Base table looks smooth but i dont understand how the base WGDC can change so much if the base table is not requesting it, what other factors could be adjusting the base WGDC? I know other tables are involved in the calculation but dont see how they could be responsible:


Thanks

Sorted, it was my spool WGDC table was too high. I logged fuel mode and seen it was at 20 when it was happening (spool mode). Im tuning the car with the WGDC floor at 35% (normally at 12.7%) to stop wastegate rattle from new 19t's. Works perfectly but makes the car very spooly so i had to reduce my base a bunch, remove most of the adder's and i forgot to remove a bunch off the spool table so i just took 5% off it which was the average between the spikes and it smooth now. Dont notice a difference in spool
