    Default Issue with Commander 950.

    A friend of mine bought a used system that we installed on a SBC with TPI. Loaded closest base map, and engine fired right up, and drove quite good. After a few miles, engine stumbled and stalled. Started right up again, ran for 300 m and died. When connecting laptop to ECU, it seem to get online. But when I open fuel map screen all values are 0, even all sensors are 0. Ignition off, load new base map on laptop. Ignition on, send to ECU. It is sending data, but it's like nothing is being stored in ECU. Checked all fuses, fuel pump is priming when turning on ignition. Checked for 5V to sensors = 5.01VDC. Any suggestions where to move on?

    In order to make changes, your key must be in the on position. Are all your Engine Parameters and Trigger set correctly set for your type of ignition?
