I'm getting a lot of flutter when the wastegate opens up. I'm tuning with ECMLink.
The car has a bolt on FP HTA GT3076R, FP race manifold, Ingersoll Rand 3 port solenoid (recommended by ECMLink) TiAL 44mm v-band waste gate with vacuum lines ran to both ports per ECMLink instructions.
When the BCS reaches the target duty cycle, the wastegate flutters. The pulls aren't nearly as clean as they should be, the AFR is unstable, etc. Originally, I had one line ran to the bottom port, running both lines helped a lot.
I have not gotten any hits about this on the ECMLink page, so I figured I'd post it here. Some guys on EvoM have had the same issue with certain solenoids, but I seem to be the only one having this issue with this valve which is supposed to be one of the better ones.
Not my car, but here's a video of what it sounds like, posted by an EvoM member click
ECMLink users are having good luck with even small springs. I did not have any issues with the Perrin MBC. I'm hoping I can resolve this without having to buy $50+ in springs for a possible solution.
I'm posting here, hoping a member has experienced something similar, whether it was on the DSM platform or not.
