Welcome to SpitFireEFI.com’s guide to using EasyTherm to modify the temperature curves in the standard MSnS-e code. After completing these steps, you will be able to program your MegaSquirt to use virtually any Intake Air Temp and Coolant Temp sensors that you desire.
Please note, that this guides assumes you’re using the latest version of EasyTherm available in the SpitFireEFI.com Downloads Section. This guide also assumes that you have a basic understanding of how to program the MegaSquirt base code onto an existing ECU. We’re also assuming that you’ve installed and configured MegaTune to work with your ECU – if you have any questions on how to do that, check out our guide on Configuring MegaTune.
First, here's a quick overview of what's covered in this walkthrough:
- Running EasyTherm and generating the required .inc files and .s19 for your specific sensor set..
- Downloading the newly created files to your MegaSquirt ECU.
- Configuring MegaTune to properly display the new temperature values
You’ve now completed all of the steps to properly using EasyTherm to create and download custom temperature and resistance curves for your particular application.
