  1. We have actually supplied a few ECUs for Biturbos over the years. The G4 range is not geared to accept a signal from coil negative as it is always best to control ignition as well. I would suggest that fitting a trigger to the crank or cam and then taking full control as the best option. An ECU that can do both functions is no more expensive. As far as a base map goes start with our default and configure and tune to suit.

  2. It would likely be easier to sell of the subaru ECU and then pick up a G4 Storm or even G4 Atom. However it could actually be done. Set up wise it will be very similar to configuring a wirein unit.

  3. The ecu will start to calculate RPM from the crank sensor when the sync pulse arrives this then tells the ECU where in the cycle the engine is and how far to a firing event. Couple of things to look for. Low voltage on crank. Too much or not enough crank enrichment. Noise from the starter getting on to the trigger wires.

  4. A really long shot but make sure your power and signal grounds are in good shape. The way the memory works does not require power to be maintained once a store has been performed. No reason for it to be any different in the car than on the bench as far as the memory goes. The settings change even with out running the engine?

  5. You will require the cam sync as with 12 evenly spaced teeth there is no way of knowing where TDC is with out one. Once it has a sync then it is not required till the next start. Sync setting must be set to cam to allow full sequential and to avoid trigger errors. For the offset it is whatever is required to time up correctly.
