CO2 boost control Holley EFI Hey guys just got into a CO2 boost control setup and I've got a couple questions about the Holley software setup. I'll have to change my plumbing up slightly but in the software is it just as easy as changing my dome control setup from compressor to fixed and setting a fixed value?? I was using Boost vs RPM with the compressor as the pressure source, can I still use that curve and PID settings or should I be going slightly more aggressive?? Since the solenoids will have a pressure source I assume I can test things out key on engine off?? Thanks guys

Anybody have an idea as to where would be a good start point for PID settings?? Seems like I get overshoot no matter where I go up or down. I haven't tried going really far down tho only P: 8, I: 20, D: 0. If I go beyond 11.5 for P term it's out of control. I have 80 psi on the regulator

I tried turning off TPS modulation but it didn't seem to want to do anything, if I turn it on then the solenoids pulse as needed. This is a bit of different ball game with co2 vs using the compressor
