Not all that glitters is gold. Although I was able to dial in and create a perfect boost curve with ECMLink, you could audibly hear the wastegate "chop" from the solenoid opening and closing through the open dump. I've seen this before and the cars pulled good. However, my experience was that the car did not seem to pull clean. I've talked to others who experienced the same. I tried different ways of trying to dampen the change in flow (or the pulse) in the vacuum lines, but I had no luck. I went back to my inline perrin unit. The perrin spikes less and holds better than my hallman, unexpectedly. The MBC doesn't give the curve I want, but the system works better.
The solenoid functions just fine on a stock wastegate actuator, which leads me to believe the issue is with your wastegate, not ECMlink or the solenoid. I'm not sure how you had your system setup, but if you have it setup with the .25 restrictor pill like normal, you probably aren't getting the pressure required to give you proper control of your wastegate. Keep in mind, the stock wastegate doesn't have a spring to work against like your 44mm WG does. Ask anyone here running ECMlink boost control, and they'll probably tell you it performs flawlessly.
Why don't you give us some more details about how you had yours set up? Were you running a restrictor? How and where did you have the lines connected?
I had it set up exactly how ECMLink suggests with the recommended IR 3 port. No restrictor. I've heard this same chop in Hondas before. I've talked a good amount to Lucas and Aaron at English about it too. After they experienced the same thing, they also went back to a MBC. I posted on the ECMLink boards and got no response. Im willing to give it another try at higher boost levels, we'll see how it does, it just pains me having to rip on the car at high power levels for the sake of trying to dial in a method in still leery about. I wonder how many people experience this chop but don't notice it (maybe from recirculating the wastegate) or really aren't aware altogether.
