From what I seen the base timing table was still used with or without the code or error present. People think dtc's put the car in open loop but that's not the case with most codes the vehicle still runs closed loop, so the pcm is still receiving data from input sensors and making live changes. A lot of older pcm's didn't have this ability and would go open loop in the event of an error code.
If he has hptuners it would be very easy to see if I'm right just log ignition timing and compare it to your map like I did.
