Boost Controller Not Working

[matthew0786]

i have a Greddy profec b spec 2, i took it to Unique AutoSports today for a Dyno tune, and they said the unit is faulty, it turns on and can view all functions

but doesnt send any signal to the solenoid valve unit so i opened the unit up, and next to the noticed that one of the diodes has been burnt out or something at the legs. I circled it in the picture in red and if anyone could give me their expert advice.

(ignore the red and blue light, its from my camera)

does it look burnt out or something because it looks like that theres black stuff that smudged the solder bit.

Any help would be appreciated, otherwise im going to send the unit to Automotive solutions to get it fixed hopefully

Usually when you fry those components they leave a strange smell. It does look to be burnt on the solder but with the rapid development of these units you can't be sure it wasn't just some dodgy workmanship. I would send it away anyway....better to be safe than sorry....especially with boost control.
