Help with Holley EFI Boost - Log and video Last Saturday was my 3rd day at the track with LS turbo build and first day using the Holley boost control. It is a dual solenoid setup using compressor source. 6 psi springs in the wastegates and I was commanding 2psi on the gate. I was using base Holley PID settings of P=10, I=30, D=0. 4,000 rpm launch and gates were holding at 5.5 psi and went to 9 psi in less than a second after releasing the trans brake.It holds 9 psi for just under 1 second then rises to 10.4 then back to 9, then 9.5 ish... So overall it isn't terrible, but I'm looking for advice on how to dial it in a little closer. Dome pressure in the logs shows quite active lol... Thinking needing to add some "D" but how much? 5 ? 10? Also I was pretty happy at the time it took to reach the rev limiter and launch boost psi. But when I went full throttle on the trans brake, it built up then hung for a split second, then came up to 4,000. I'm curious if and how I could tune that out. In looking at the log overlays in spark and fuel it was clear, but then I thought perhaps it just came up on boost which allowed it to power through the converter. Any advice in general on the log would be great. Have learned a lot but have a long way to go.
