00:00 One of the most important tasks when tuning any engine is to set the base ignition timing.
00:04 This means calibrating the ECU so that the ignition advance number that the ECU is displaying on the laptop screen, is the same as the ignition advance the engine is seeing, if you put a timing light on it.
00:16 Without doing this, the actual ignition timing could be anywhere, and if that happens to be over advanced, this could result in serious engine damage.
00:25 While it isn't quite as critical as the base ignition timing, base fuel pressure has a big impact on the amount your fuel injectors can flow, and this will also affect the injected dead time, or injector characterization numbers.
00:37 It's important to get this right, too.
