Ive been using my Greddy profec b spec II for a year now, no issues, love the controller. I went on a vacation back in december and the car sat for 4 days. when i came back i found that my controller had basically flashed itself and all settings were set back to factory and set back to KPa readings.

so i set it all back.

well so far its done it twice since the first time. WTF??? Why is the flash memory FLASHING ITSELF. ive never seen this.

 

mine does this sometimes too. all the settings get reset, its kind of a pain in the ***. i really dont have an answer for you but just wanted to let you know that i had experienced the same thing with the same controller. maybe call greddy and ask them whats up?

usually i dont notice it until i start boosting and the turbo feels so laggy. for EBC's

 

it didnt do it over the summer, maybe the cold ***** with it??
