  1. Thanks for your insight CJ! I changed boost rpm activation to 9000 rpm and zeroed boost target values. The car drove without hesitation after. I drove prior to making the change. As soon as boost table was activated, the hesitation started. The pedal input is rpm dependent. The hesitation made it really bad. I can add more aggressive throttle response now that its sorted. I will investigate the trigger signal next. I appreciate you good work. Thank you.
  2. Hello All, I am at my wit's end. I also fully recognize that I am not a tuning expert. Part throttle when cruising the engine runs richer below AFR target. This shaking can be exaggerated if I was to accelerate at low rpm. It makes strange surging sounds. It is a 2L 4cyl engine with a K04 turbo iwg, and a 80mm DBW throttle. It will do this with accel enrichment off + CLL off. Looks like the injector Effective PW oscilates. I am still on waste gate pressure 6psi. This log does not show my fuel pressure, I did start logging that after. It looks smooth (3 bar fpr). I am using a somewhat obsolete LC-1 Wideband controller. It was free air configured. I plan to switch to an LSU-ADV O2 Bosch sensor with Spartan 3 Controller soon. P.S. does the engine speed signal appear noisy? Any insight is much appreciated. Log 2019-08-6 9;05;39 pm.llg
