If you put carbs on then you will be deriving the ECU of sensor information from the MAP/MAF and the TPS. Without these informations the ECU cannot lookup the correct ignition advance reference on the ignition 3d map so you will be running with a set ignition timing i suspect.

It would be easy to test with a timing light and by revving the engine, just check if the advance stays the same.

This is very poor for engine performance, i would fix it.

To use the OE ecu you will need to hook up a vacuum manifold and run the MAP sensor off it, along with the brake servo (i hope your car is MAP not MAF).

You will also need to adapt the TPS sensor to the carb spindle and then reset the values to stock for idle and WOT.
