Mapping is like two faces: one side very simple thing – you only need to control air, fuel and ignition. One side is very complex adjustments which no many people understand. In this album I will simply show you the “BASIC” information of mapping set up by Megasquirt system (Tuner Studio MS).

There is a lot of information from above website for mapping information – but I have to tell you…..most people just simply lost inside ton of ton’s information.
MegaSquirt is a powerful and inexpensive mappable ECU that can be programmed or configured to work with any vehicles. The method to install the MegaSquirt is to link from the MS ECU to the engine stock sensors or upgrade sensors to control / alter fuel and spark.
The most common sensors for Megasquirt system to control fuel and spark are: throttle position sensor, coolant & air intake temperature sensors, O2 sensor, idle air control sensor, injector, crankshaft position sensor and MAP/ MAF sensor. More other sensors can be added on to control nitrous, water injection, boost control and knock control, etc
Set a number of correct parameters that will determine how MS TunerStudio performs. These basic set up include engine constants, required fuel, ignition setting, injector characteristics, and trigger wheel setting etc. These constants are either calculated, or based on the configuration of the engine. Setting pictures were screen shot from the MS TunerStudio.
The engine specification is based from a Global GT Light 1000c 4 cylinders engine race car. All the setting recommendations are from www.extraefi.co.uk.
