Fuel Compensations

00.42

00:00 So far we have discussed how to approach tuning the main fuel table in the ECU.
00:05 Most modern ECUs will also provide the ability to compensate the fuel delivery as the engine's operating parameters change.
00:13 These compensations include air temperature, engine temperature, and perhaps road speed or gear.
00:20 We can make use of these compensation tables to make our tuning more consistent as the engine's operating conditions change, and we can also manipulate them to improve safety and engine reliability.
