While the way an engine responds to ignition timing is the same regardless what ECU you're tuning, optimising the ignition timing on a factory ECU does require a different approach compared to tuning an aftermarket ECU. In this webinar we will investigate how to optimise ignition timing in the GM E38 PCM. We will also see how to use the scanner to decide where to make changes to the table. 

For this webinar we will be using a 2013 HSV R8 Clubsport and the HP Tuners software. For more information about reflashing see the Practical Reflash Tuning course
