Running a 3 port mac valve through ms3x. Use to run fine but now seems to vent boost as soon as it comes online. Have replaced the solenoid with another unit and it does exactly the same thing. Wondering if anyone else has had the same issue?
Settings and log file below. Controller is correctly hooked up to high current out 3
Really hard to say anything about that, you showed an image of a log at idle, where you don’t even get to atmospheric pressure (100kpa). All I see is your rpm dropping.

I can't drive the car with the boost control turned on, idle AFR's shoot down to low 9's when the coolant temp reaches 60C and the boost controller comes online. If I turn boost control off this doesn't happen
Couple strange questions, I know, but bare with me — what crank sensing method are you using? If trigger wheel at crank, check the gap and also the connection wires
Are any other parameters coolant temp controlled — rev limiter, anything?

Still using the CAS, don't have a trigger wheel. Spark mode is 4G63 running with LS coils. Here's a pic of pin usage

Rev limiter is coolant temp controlled and works fine
