Boost aim

[Jimes]

Hi all bit of a newb here. M400 running on vw 2.0tfsi race car. N75 valve on aux 1 output and as far as I can see everything set for open loop boost control. But no matter what I do, adjusting boost aim table makes no difference to duty cycle? Any pointers for me to check? Thanks

Has this previously been working, and now it has stopped, or is this a new installation and setup?

If it's new, you should upload your M400 Configuration so we can see what you've done. How is the auxilary output wired? Is the other side of the valve getting power?

It’s a 2nd hand unit so maybe setup wrong somewhere. It activates valve when testing aux 1.
