Ok. First off IF the dizzy was not put in properly it may not fire at all.
Assuming the engine builder put the timing chain kit in properly and you installed the dizzy properly this engine should run

Then as it goes from open to closed loop mode over time the brain learns from the inputs from the sensors and averages out the amounts.
