Hondata PMW issue

ECU - P06 Hondata v2 s300

My Hondata has been working fine for the past year running on a boost controller. Last night I decided to change it to boost by gear with PWM.

Once connecting my boost solenoid to A11 and to 12v. The Hondata program would freeze and crash. After re booting up the hondata would stop letting me upload and download and it won’t even recognize the Hondata.
The engine won’t start at all.

If I disconnect the boost solenoid 12v, Hondata runs flawless and starts again.

Any help would be awesome

Post pictures of the inside of the ECU and how you have it wired.

Has Q20 been installed?

Have you replaced the capacitors that appear to have leaked?
