Ignition tuning is often misunderstood by those new to tuning, and it can have serious consequences when we get it wrong in a high load/high boost area of our tuning table/calibration map. Using a low-load area of the map and a Haltech ECU-equipped Mitsubishi EVO 9 with a turbocharged 4g63, let's examine what advancing or reducing our ignition timing angle does via a torque optimisation test on a Mainline dyno. We'll examine why we want to have our ignition angle spot on and where that place is in our compression stroke, as well as what happens when we stray too far on either side. We'll also consider some things that might prevent us from finding our MBT value, including knock/pinging/detonation/pinking, which is not to be mistaken for the commonly incorrectly used term pre-ignition.
