# AiM Dashes and SmartyCams The best content [is on the forums](https://rush.sr/) for the AiM dash, data downloads, and using your SmartyCam. These fantastic products work together as one unit. If ordered with your car, no customization is necessary for good results. However, if you want to start adding more data overlays or learning from your data, you might benefit from the following: * [How-To: Configure Your Smartycam - Throttle, Brake, Overlays and More!](https://rush.sr/threads/how-to-configure-your-smartycam-throttle-brake-overlays-and-more.12/) * [How-To: Create Custom AiM Dash Layouts](https://rush.sr/threads/how-to-create-custom-aim-dash-layouts.51/) * [How-To: Export a lap video from RaceStudio 3](https://rush.sr/threads/how-to-exporting-a-lap-video-from-racestudio-3.189/) * [How-To: Render Video Without a SmartyCam](https://rush.sr/threads/how-to-render-video-without-a-smartycam-nasa-december-17-18-2022-sebring-fl.3/) See also the section on [Dash Alarms](/at-the-track/aim-dashes-and-smartycams/dash-alarms.md), which are managed in RaceStudio 3. ## AiM Config Downloads Rush Auto Works publishes [versioned config releases on GitHub](https://github.com/Rush-Auto-Works/aim-config-releases/releases). Download the `.zconf2` file that matches your dash and car type, then import it in RaceStudio 3 under **Configurations → Import**. ## Custom Sensors If your car has aftermarket sensors (fuel level sender, brake pressure transducers, etc.), you'll need to install the matching sensor definition in RS3 before it can read the channel correctly. Sensor files (`.snsr`) are available in the [latest release](https://github.com/Rush-Auto-Works/aim-config-releases/releases/latest) alongside the config files. ### Installing a Fuel Level Sender Rush SRs with the optional fuel level sender use a custom calibration curve. {% hint style="success" %} **Already have a 6-gallon tank?** The default Rush configs from the [releases page](https://github.com/Rush-Auto-Works/aim-config-releases/releases/latest) come with the 6-gallon fuel sender already configured on Ch04. If you have your own custom config, use the [AiM Config Merge Tool](https://rushautoworks.com/aim-config-merge/) to pull in the sensor definitions without losing your personal settings. {% endhint %} If you need to set up a fuel sender manually (e.g., switching to the 12-gallon endurance tank, or starting from a non-Rush config): 1. Download the appropriate sensor file from the [releases page](https://github.com/Rush-Auto-Works/aim-config-releases/releases/latest): * **6gal fuel level sender.snsr** — for the standard 6-gallon Rush SR tank * **12gal fuel level sender.snsr** — for the 12-gallon endurance tank 2. In RaceStudio 3, click the **Custom Sensors** button in the toolbar (the fluid temperature icon shown below), then click **Import** and select the `.snsr` file.

The Custom Sensors button in the RS3 toolbar.

3\. Open your configuration and go to the \*\*Channels\*\* tab. Click on \*\*Ch04\*\* (Fuel Level).

Channels tab showing sensor assignments. Ch04 is the fuel level channel.

4. In the Channel Settings dialog, set **Function** to "Fuel Level" and click the **Sensor** dropdown. Select **Custom**, then choose the Rush fuel sender you imported (e.g., "RAW 6gal Fuel Sender").

Selecting the custom fuel sender sensor under Custom sensors.

5. Click **Save**, then **Transmit** the configuration to your dash. ### Adding Fuel Level to Your Dash Display Once the fuel sender is configured, you can add it to any dash page: 1. Go to the **Display** tab and click on the dash page you want to edit. 2. Click on a display location where you want the fuel level to appear. 3. In the channel selector, choose **A/D Channels → Fuel Level 6galT**. 4. Click **Save**, then **Transmit**.

Adding Fuel Level to a dash page. Select the location, then pick Fuel Level 6galT under A/D Channels.

## Upgrading MXm to MXS The MXm and every version of the MXS (1.x and 2) are drop-in interchangeable on the Rush SR. To swap: 1. Disconnect the motorsport connector from the back of the existing dash logger. 2. Unbolt the dash from the panel. 3. Bolt on the new dash logger. 4. Reconnect the motorsport connector. {% hint style="warning" %} The MXS 1.x and MXS 2 use different RaceStudio configurations — make sure you flash the matching `.zconf2` from the [AiM Config Downloads](#aim-config-downloads) section before driving. Files for both generations are published on the [aim-config-releases](https://github.com/Rush-Auto-Works/aim-config-releases/releases/latest) GitHub releases page. {% endhint %} {% hint style="info" %} The connector labels on the MXm and MXS harnesses differ slightly (for example, the SmartyCam input is labeled **CAN EXT** on the MXS harness and **CAN EXT 2** on the MXm harness). Every AiM logger ships with its own harness, so if you're upgrading you'll have a spare — it's worth swapping to the matching harness so future troubleshooting matches what's printed on the connectors. If you bought a replacement MXS without a harness, you don't need to swap. {% endhint %} {% hint style="warning" %} The square 4-pin connector on the back of the MXm is **not** cross-compatible with the MXS. The Rush SR stock setup doesn't use this connector, so it's only a concern if you've wired something custom into it. {% endhint %} ## SmartyCam Compatibility Both the SmartyCam single (HD) and SmartyCam dual work with either the MXm or any version of the MXS. The SmartyCam box connects to the dash logger harness with a CAN cable plugged into the **CAN EXT** connector (labeled **CAN EXT 2** on MXm harnesses). The **dual** SmartyCam additionally needs 12V and ground. Rush's factory install uses a short pigtail that taps 12V from the back of the dash switches and grounds via a ring terminal on one of the bodywork pin plates. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
