Resumen

00:00 - Ed Cronado has asked, in a turbo car, are there other values to take into consideration compared to naturally aspirated? Not really, I think when it comes to turbocharged cars, again there's a misconception out there that these are really really special and completely different to tune than a naturally aspirated engine.
00:18 The reality is is that they are really exactly the same.
00:21 What we need to understand is that with a turbocharged or supercharged engine, we're forcing more air and fuel into the cylinder when we move into positive boost pressure.
00:30 So the two trends that we have for our fuel and ignition tables still are the same.
00:36 Remember with our ignition table as we increase the airflow into the engine or the load into the engine, we're going to retard the timing.
00:42 So as we move past that atmospheric pressure out into the positive boost areas of our ignition map, we're going to need to retard the timing compared to what we had at atmospheric pressure or 100 kPa.
00:54 With our fuelling what we do is exactly the same, remember we're using a portion of our fuel to help control our combustion chamber temperature.
01:02 Because we're burning more fuel and air with a forced induction engine, we're producing more heat so we need to run a richer air/fuel ratio in a turbocharged engine compared to what we'd run on a naturally aspirated engine.
01:14 In terms of other values, of course we may want to take into account boost control in our tuning strategy to adjust our boost pressure.
01:24 So really very very similar.
