PWM Boost Control

I am having trouble getting the PWM boost control to work. I have used every array of settings I can think of, but the boost is only running off the wastegate (roughly 5.2). I have checked all the wiring and I am running the suppressive diode. The car is a 97 Accord with h22a4 running E-85, p28 ecu ordered through HA mototsports (they did all the chipping and components). I am using the genuine Hondata boost control solenoid.

Can I use a volt meter to check the output from A11, and if so what readings should I be getting when it shouldn't be activated vs when it should be activated?

Any other thoughts of what I should try?

Recent datalog and calibration attached.

Thank you

try using the gear based duty cycle and see if you can hit 9psi. also i would work your boost table af's currently there is alot od 12.6 and 12.5 under boost. try making it 12 or 11.5. everything looked like it was working correctly in your log.
