What you can take away from this is how inconsistent the factory timing control is on these cars.
Nothing has changed mechanically on the car yet the factory ecu runs a different timing curve almost every time I pull the car.
For those NA guys this might not be a big deal because it's not going to blow up your motor, but on forced induction guys that extra 2 degrees of timing the ecu *might* add could be a problem.
With the EcuTek's RaceRom ignition control we are able to bypass the OEM timing logic which is in calculated burn time with real ignition maps that do what we want all while keeping Knock Control
