Can you datalog with the key on engine off? If you can and then it stops once you start the engine then the problem is electrical noise. Check the master ground near the thermostat housing and check that you have stock plug wires with resistor type spark plugs.

Can you test the car with the stock ignition system?

The problem is most likely the MSD...first try moving it away form the ecu, and if that does not work try the stock ignition system. We have seen aftermarket ignition systems generate a lot of electrical noise which interferes with datalogging.

We made 700+ with stock ignition and 650+ serveral times. If you want a GOOD system because you think you need it, look at M&W.
