Asking for help from those good with the ecu circuitry. First off let me say that the I have never gotten the pwm components to work in this ecu although they are installed correctly. What I want to know is if my ecu is missing additional components that is preventing the pwm components from working. I know that it's not an external wiring problem because I've tried another obd 1 tuning solution and it has worked flawlessly. All I did was unplug that ecu and put in a p28 with the s300 and nothing for pwm. Perhaps in a later software release, hondata could put a test feature for pwm to make sure the solenoid is ticking. I have never seen the pwm datalog button indicate "on" nor ever hear any ticking from the solenoid. Now for information:-
1. the ecu is a p28 with s300 installed.
2. the board is IPT and the number is 02D011F0-1500
3. In the smanager software in the show ecu info, everything is green ticked.
4. firmware version is 1.04
5. here are some pics of the ecu with the pwm components installed. They were bought from Xenocron and the install directions for components were followed.IMG_1835

The only thing I have done is to cut r136 and r138 to get the plx wideband to read better. I have noticed that j12 looks like it might have had something removed from there. Other than that I am open to suggestions about what could be missinf from the a11 circuit. Thanks all!!
