I'm having a few problems resetting my prova ecu. The ecu is showing fault codes 45 and 31 and have tried to reset and clear without success. I have a std ecu which runs fine but would like to run the prova again. Both ecu's were sent off to be checked due to a problem I was having and both ecu's were sent back to me giving the all clear. I am also overboosting on the prova ecu @ around 4500rpm. Both ecu's are 2c on a 93 wrx wagon with a td05, induction kit and magnex rear box. Anyone have any ideas to why the prova wont reset?
