WPeak wpeakjr Joined: Mar 2012 Posts: 52 KY, USA	We have been fighting the same issue for a while on this car. We have been thru several items as far as the following: Sent all boards (DSP, PMI; etc.) for testing and repair. Changed 5v power supply and set to 5.1 Checked for AC leakage into my DC power supply Changed the molex connectors on the DSP card Changed the governor encoder board. I get faults 109, 52, and 812. 109 = Encoder Cross Check Error 52 = Tach Fault Warning 812 Positive Torque Limit It is highly intermittent and will run at times for a week or more. Any help is appreciated.
