The VE (volumetric efficiency) table represents the main fuel map for the engine and is where you will be doing most of your tuning. Once tuning of the light load area of the map is complete, it can be set back to 30% to enable closed loop correction. For your initial tuning, this number should be set to zero (0) to disable closed loop. The 'Controller Authority' tells the ECU how much it can change the mixture to achieve the A/F ratio set in 'EGO Switch Point'. These settings control how the oxygen sensor is used to adjust the mixture under closed loop. This is correct, because even though we have 4, the secondaries are staged and not always operating. Note that the number of injectors is set to two. These settings are the basic characteristics of the engine. We start with the most basic characteristics of the engine. The settings are presented below in a list with the title of each item representing the menu choices needed to open up those settings. With each screen I will give you the basic idea of what the settings do but if you want to know more, it is up to you to look it up. To do so would be a monumental task and simply repeat information in the Megasquirt manuals. I am not going to explain in detail every setting on this page. Otherwise the changes are made to the map in TunerStudio but not sent to the ECU.

If you are programming the ECU live, make sure to press 'Burn To ECU' before closing each window. You can then load that MSQ into the ECU when you are in the car. You can work on this MSQ offline if you find it more convenient than sitting in the car typing in settings. But do not start with a blank map! Open up TunerStudio and connect to your ECU to download all the settings. Keep in mind that you don't have to be connected to the ECU to make these settings. Any settings that are not mentioned can just be left default. Each settings page will be shown with a chart of the settings, and a screenshot of what they look like. These settings vary greatly between MSI and MSII so this section is divided up to cover each ECU separately. Set LAMBDA_SENSOR to 'AEM_LINEAR - AEM Gauge AEM-30-42xx' and IDLE_CONTROLLER to 'PWM_GAUGE - PWM Idle Valve (e.g., Ford or Bosch)'.Ĭonfigure The ECU To Run The Rotary Engineīasic parameters need to be set up in the ECU to tell it the displacement of the engine, how many injectors it has, the trigger and ignition setup and what to do with it's outputs. Note that when you are configuring TunerStudio, you need to select the appropriate Lambda Sensor and Idle Controller. DIYAutoTune has some great generic TunerStudio setup instructions. The first time you run TunerStudio you will need to create a project for your ECU. Power up your Megasquirt and make sure that it is responding to inputs.

The free version will suffice for now however you may want to upgrade to the paid version when you start tuning as only the paid version can autotune the VE table.

We'll do that later.Īt this point, if you have not already downloaded TunerStudio MS, do so now and install it.

For MS1, see the MSnS-Extra Software Manual for instructions on low to load the latest version of MSI/Extra.ĭon't bother following the instructions on the above websites to configure the Megasquirt to your engine. It is therefore necessary to load the Megasquirt and Spark Extra (MSnSE) firmware.ĭisconnect the ignition coils from the harness before proceeding! Failure to do this will burn out the coils! The stock Bowling & Grippo firmware loaded onto Megasquirt CPUs from the factory will run the rotary, but it will run fuel only and without a lot of the features we depend on (such as staged injection). For convenience I've reproduced those instructions here. If you have not already done so using a Stimulator during the build/modding section the first step is to flash the appropriate firmware into the Megasquirt. Make sure you are reading the correct page for your ECU version. Because there is such a difference between the setup of the various MegaSquirt versions, each ECU has it's own configuration page. This section covers programming the MS1 ECU to run the 13B rotary.
