Well I've had trouble with ecu even before I received it in the mail but I'd rather not get into that at the moment. Anyhow, the ECU has a UNI 630cc BT file on it, however, there are 4 EPC codes that are stuck in the ECU and not able to be cleared. Does anyone have any idea if these can be fixed or is the ECU now worthless. The car will not stay running with the epc codes stuck in the ecu. Any help would be great, thanks.
